Returning to Play for High School Athletes: Part 1

Ever watch your star player go down with a knee injury, see a shoulder pop out during a tackle, or witness an ankle roll on the court? These moments are gut-wrenching for athletes, parents, and coaches alike. But here's the good news: most high school athletes can successfully return to their sport after these common injuries — if they follow the right roadmap for physical recovery.

Let's break down what it takes to get physically cleared for return to play after an ACL tear, shoulder dislocation, or ankle sprain.

 

The ACL Injury: A Marathon, Not a Sprint

An ACL tear is one of the most feared injuries in youth sports, and for good reason. Nearly a quarter of a million ACL injuries occur annually in the US and Canada, with rates in high school athletes reaching 5.5 per 100,000 athlete exposures. But here's what many don't realize: getting back on the field isn't just about healing — it's about meeting specific physical benchmarks.

The minimum timeline is 9 months from surgery, and that's not arbitrary. Your body needs time for the graft to incorporate biologically, and rushing back increases reinjury risk dramatically. In fact, athletes who returned before 9 months had significantly higher rates of reinjury compared to those who waited.

But time alone isn't enough. Athletes must achieve at least 90% limb symmetry index (LSI) for both quadriceps strength and hop testing before getting cleared for competition. This means the injured leg needs to perform at 90% or better compared to the uninjured leg. Athletes who met these criteria had a reinjury rate of just 4.5% within 2 years, compared to 33% in those who didn't meet the criteria.

The recovery follows a structured, mulit-phase approach:

  • Early phase (weeks 0-6): Focus on reducing swelling, restoring range of motion to 0-115 degrees, and achieving 60% quadriceps strength symmetry

  • Intermediate phase (weeks 7-9): Progress to 70% strength symmetry with full, symmetrical range of motion

  • Late phase (weeks 10-16): Reach 75-80% strength symmetry and begin running when you hit 80% and can demonstrate single leg squats, step downs and hops with good mechanics

  • Transitional phase (months 4-6): Introduce jumping, sprinting, and agility drills at 85% strength symmetry

  • Return-to-sport phase (months 6-12): Sport-specific training with final clearance requiring 90% symmetry, no pain or swelling, and adequate confidence levels

Here's the reality check: only 40-55% of athletes return to their pre-injury activity level after ACL reconstruction. Even among highly motivated European professional soccer players with excellent resources, only 65% returned to their previous level. This isn't meant to discourage — it's meant to emphasize the importance of working with a sports physical therapist and following a comprehensive plan.

 

Shoulder Dislocations: High Risk, But Quick Recovery Possible

The shoulder is the most commonly dislocated joint in the body, and it usually dislocates anteriorly (toward the front). For high school athletes, especially those in contact and collision sports, this injury comes with a sobering statistic: recurrence rates can reach up to 90% in active patients younger than 25 years.

But here's where shoulder dislocations differ from ACL injuries: return to play can happen as early as 2-3 weeks after injury for athletes who are pain-free, have symmetrical shoulder range of motion, and can perform sport-specific motions. Some athletes with recurrent dislocations who experience easy relocation, minimal pain, full range of motion, and protective strength may even return the same day.

The treatment approach depends on several factors:

Immediate management:

  • Attempted relocation on the field before muscle spasm develops

  • Neurovascular assessment before and after reduction

  • Immobilization and pain management after successful reduction

  • Post-reduction radiographs after first-time dislocation

Recovery protocol:

  • Sling use for 2-4 weeks for comfort (though current evidence doesn't mandate a specific duration)

  • Graduated rehabilitation focusing on passive and active range of motion

  • Physical therapy addressing joint range of motion, scapular control, rotator cuff strength, and sport-specific conditioning

Surgical considerations: Surgery should be considered for first-time dislocations in active patients under 25 due to the extremely high recurrence rate, or when there are complications like large bony defects.

Interestingly, research on high school athletes shows that 85% of those treated nonoperatively successfully returned to their sport and completed at least one full season without additional injury. Athletes with subluxations (partial dislocations) fared even better, with an 89% success rate compared to 26% for complete dislocations.

 

Ankle Sprains: The Most Common Culprit

Ankle sprains are the most common foot-ankle and sports-related injury for which people seek medical care. Four in every 10 first-time ankle sprains occur during sports participation. The good news? Most athletes bounce back quickly.!

High school athletes have a 75% chance of returning to sport within 3 days after a first-time , Grade I ankle sprain, and a 95% chance within 10 days. In college athletics, 44.4% of athletes returned to play in less than 24 hours. However, more severe Grade II and III sprains involving multiple ligaments can sideline athletes for more than 3 weeks.

The key to successful return involves addressing five critical domains — the PAASS framework:

  • Pain: Both during sport participation and over the last 24 hours

  • Ankle impairments: Range of motion, muscle strength, endurance, and power

  • Athlete perception: Confidence, reassurance, stability, and psychological readiness

  • Sensorimotor control: Proprioception and dynamic postural control/balance

  • Sport/functional performance: Hopping, jumping, agility, sport-specific drills, and ability to complete a full training session

Supervised exercise programs addressing strength, coordination, proprioception, and functional deficits lead to faster return to sports. Evidence also supports the use of compression stockings and anteroposterior ankle joint mobilization for quicker recovery.

General return-to-work and sport guidelines suggest:

  • Return to sedentary work: 2-6 weeks following injury

  • Return to physical occupations and sports: 6-8 weeks

These timelines should be adjusted based on injury severity, rehabilitation response, and specific task requirements. Working with a sports medicine clinician will be key for determining optimal readiness.

 

TOOLS FOR BUILDING CONFIDENCE

Resistance bands, balance pads and boards, and BFR cuffs are a few of the essential tools in rehabilitation. Resistance bands safely build strength, balance pads enhance coordination and stability, and BFR cuffs accelerate recovery through low-load training.

The Bottom Line

Physical clearance for return to play isn't one-size-fits-all. ACL injuries require the longest recovery with the most stringent criteria — minimum 9 months and 90% strength symmetry. Shoulder dislocations can allow quicker return (2-3 weeks) but carry high recurrence risk in young athletes. Ankle sprains typically resolve fastest, with most athletes back within days to weeks.

The common thread? Meeting objective physical criteria matters more than arbitrary timelines. Pain-free movement, symmetrical strength, full range of motion, and sport-specific performance capabilities aren't just checkboxes — they're your best insurance against reinjury.

In Part 2, we'll explore the mental side of return to play — because as we've learned, physical readiness is only half the battle.

Choosing A Clinician: A Guide for Athletes and Active Individuals

Whether you’re a seasoned athlete or simply someone who enjoys staying active, finding the right sports physical therapist can make all the difference in your recovery and performance. Sports physical therapists specialize in treating injuries and optimizing movement for individuals with active lifestyles. They work closely with athletes and fitness enthusiasts to help them get back to their peak condition safely and effectively. But with so many options out there, how do you choose the best one for you? Here’s what to look for when selecting a great sports physical therapist, including key qualities of both the clinician and the practice setting.

The Clinician:

1. Expertise in Sports-Related Injuries and Conditions

A good sports physical therapist has extensive knowledge and experience in managing sports-related injuries. Look for a therapist who:

  • Has experience treating injuries specific to your sport or activity. For instance, if you’re a runner, a therapist with experience in managing lower extremity injuries, such as shin splints or knee issues, will be invaluable.

  • Is certified or has a background in sports physical therapy. Certifications like the SCS (Sports Certified Specialist) indicate a strong foundation in sports injury management and rehabilitation.

  • Understands biomechanics and movement patterns specific to athletic activities. This knowledge is crucial for evaluating how you move and pinpointing any issues that may be causing or exacerbating your injury.

2. A Patient-Centered Approach and Strong Communication Skills

One of the most important qualities of a good sports physical therapist is the ability to listen to and understand your goals, needs, and concerns. Look for a therapist who:

  • Takes the time to listen to your story and understand how your injury affects your life and sport.

  • Communicates clearly about your diagnosis, treatment plan, and expected outcomes. They should be able to explain complex concepts in a way that you understand and feel comfortable with.

  • Values your goals and collaborates with you to create a recovery plan that supports both your short-term and long-term aspirations, whether that’s getting back to training or just enjoying a pain-free workout.

3. Customized, Sport-Specific Treatment Plans

No two injuries are alike, and athletes require specialized care tailored to their sport’s unique demands. A good sports physical therapist will:

  • Create a customized treatment plan that’s specifically designed to address your injury, taking into account your sport, position, and level of play.

  • Incorporate sport-specific exercises and progressions. For instance, if you’re a soccer player, your therapist should include drills that mimic the movement patterns used in soccer, like pivoting and kicking.

  • Focus not only on healing the injury but also on injury prevention. A great therapist will identify areas of weakness or instability that may lead to future issues and work with you to build strength and resilience in those areas.

4. Emphasis on Functional and Return-to-Sport Testing

A skilled sports physical therapist knows that recovery isn’t just about feeling better; it’s about getting back to performing at your best. Look for someone who:

  • Uses functional testing and return-to-sport assessments to objectively measure your readiness to return to your sport. These assessments help determine if you’re truly ready for the demands of your activity and reduce the risk of re-injury.

  • Tracks and evaluates progress over time to ensure you’re moving forward with your recovery.

  • Is willing to adapt the plan based on your progress and any challenges you face along the way.

The Practice Setting:

Alongside the characteristics of the therapist, the practice setting itself plays a crucial role in supporting effective treatment. Here’s what to look for in an ideal sports physical therapy setting:

1. Well-Equipped Facility with Sports-Specific Equipment

A good sports physical therapy clinic will have specialized equipment and spaces that allow for sport-specific rehabilitation. Look for a facility that includes:

  • Strength and conditioning equipment (like squat racks, resistance bands, free weights) to facilitate sport-specific strengthening and conditioning exercises.

  • Open space for dynamic exercises such as running, jumping, or agility drills. This allows for a full range of motion activities and sports-specific drills.

  • Advanced equipment for functional assessments and movement analysis, such as motion capture or force plates, which can provide valuable data on your biomechanics and movement patterns.

2. Collaborative, Interdisciplinary Team

In the best sports physical therapy clinics, therapists often work alongside other health and fitness professionals. This type of collaborative environment can be extremely beneficial if you need additional support, such as:

  • Sports medicine physicians and orthopedic specialists who can provide input on complex cases or guide the treatment plan based on specific medical needs.

  • Athletic trainers and strength coaches who can help transition you from rehabilitation to performance training.

  • Massage therapists who help treat soft tissue injuries and optimize recovery.

  • Nutritionists and mental health professionals who understand the unique demands placed on athletes and can support holistic recovery and wellness.

3. Emphasis on Education and Injury Prevention

An ideal sports physical therapy practice not only treats injuries but also focuses on educating athletes to prevent future issues. The clinic should provide:

  • Resources on injury prevention techniques, warm-up and cool-down strategies, and sport-specific conditioning tips.

  • Access to self-management tools (such as foam rollers, resistance bands, and instructional videos) to help you maintain your progress outside of the clinic.

  • Follow-up care or programs to support continued improvement after your primary treatment has ended.

Final Thoughts: Finding the Right Fit

Ultimately, finding a good sports physical therapist is about finding someone who understands your sport, values your goals, and has the expertise and resources to support your recovery journey. Take the time to ask questions, explore different clinics, and find a therapist and setting that feels right for you. The right therapist will not only help you recover from injury but also empower you to return stronger, more resilient, and better prepared to reach your full athletic potential.

Therapeutic Applications of Heat vs Cold

If you've ever had an injury—whether it's a sprained ankle from running or joint stiffness after a long day—you've probably wondered: Should I grab an ice pack or reach for a heating pad? The truth is, both cold and heat therapies have their place in both recovery and injury rehabilitation. But knowing when to use each can make all the difference in your healing process.

Cold Therapy

Cold therapy, also known as cryotherapy, is the go-to for acute injuries. Think sudden sprains, strains, or any type of trauma where swelling is your body's immediate response. Ice helps to reduce swelling, numb the pain, and limit damage to the tissues.

How It Works:
When you apply cold, it causes blood vessels to constrict (Knight & Draper, 2013). This reduces blood flow, which means less swelling. It also numbs the area, providing almost instant pain relief—especially useful during the first 48 hours after injury. Research indicates that cryotherapy is particularly effective at reducing swelling and pain during the initial phase after an injury or surgery (Hubbard & Denegar, 2004). Some common methods include:

  • Ice packs or gel packs: Quick and easy for small areas like a sprained wrist or ankle.

  • Ice baths: Athletes swear by these for post-exercise recovery, especially after intense training.

  • Cryotherapy chambers: More intense, these are becoming popular for whole-body cold therapy.

When to Use It:
Cold therapy is most effective within 48 hours of injury and should be applied for no more than 20 minutes at a time. It’s is perfect for:

  • Acute injuries (sprains, strains, or fractures)

  • Reducing post-workout soreness

  • Controlling post-surgical swelling

What to Watch Out For:

  • Do not apply ice directly to your skin—it can cause frostbite. Always wrap it in a towel or cloth to protect yourself.

  • Cold therapy should also be avoided if you have poor circulation or conditions like Raynaud’s disease. 

Additionally, it's important to note that while ice can reduce pain and swelling in the short term, the long-term benefits of cryotherapy, particularly on tissue repair and recovery, remain unclear (Hubbard & Denegar, 2004).

Heat Therapy

Where cold therapy excels at calming inflammation, heat therapy is ideal for those days when your muscles are tight and your joints feel stiff. Heat is a great way to increase blood flow and relax the muscles. It’s perfect for anyone dealing with chronic pain or conditions like arthritis.

How It Works:
Applying heat causes blood vessels to dilate, allowing more oxygen and nutrients to reach sore areas. This helps relax tight muscles, soothe joint pain, and improve flexibility (Knight & Draper, 2013). There are two main types of heat therapy:

  • Dry heat: Heating pads or an infrared sauna.

  • Moist heat: Warm baths or steamed towels, which penetrate deeper into the muscles.

When to Use It:
Heat therapy can be beneficial before activities that require significant flexibility or range of motion. It’s recommended to apply heat for 20-30 minutes, and works best for:

  • Chronic neck or back pain

  • Joint stiffness from arthritis

  • Muscle tightness or spasms

What to Watch Out For:

  • Be careful not to use heat on new injuries or swollen areas. It can actually make swelling worse. 

  • Make sure the heat is comfortable, not too hot, to avoid burns.

Can You Combine Cold and Heat?

If you’re wondering whether you can use both, the answer is yes. This is known as contrast therapy, where you alternate between cold and heat. Cold reduces the swelling, and heat increases blood flow and mobility.

Contrast therapy is especially useful for:

  • Soft tissue injuries

  • Post-surgical recovery

  • Reducing muscle tension after exercise

Listen to Your Body

At the end of the day, both cold and heat therapies are powerful tools, but they aren’t one-size-fits-all. The right treatment depends on your specific condition and how your body responds. Always consult with a healthcare professional if you are unsure, especially if your symptoms persist or worsen.

Cold and heat therapies are simple but effective ways to manage pain, reduce inflammation, and promote recovery. Whether you’re dealing with a new injury or chronic stiffness, using these therapies correctly can help you get back to doing what you love—without unnecessary setbacks.

What is an Athletic Trainer

While both are casually referred to as “trainers”, personal trainer and athletic trainers are two very different roles. Personal trainers generally work in gyms and health clubs, helping the general public improve their level of fitness; Athletic trainers are most often found at colleges, hospitals, clinics and with professional sporting or performance organizations, helping patients or athletes recuperate from injuries and safely continue to participate in sports and physically demanding professions. Below, we’ll dive into the two professions in greater detail:

Personal Trainers

Personal trainers evaluate a person’s fitness level and then design with an exercise program to improve the individual’s health, cardiovascular endurance and body composition. They teach clients how to perform exercises properly, while creating an atmosphere of accountability. Personal trainers with additional credentialing can also education clients on how to live a healthier lifestyle, coaching them on nutrition basics and recovery strategies.

While there is no governing body for personal training, it’s highly recommended to select a personal trainer who has completed a certification program; there are several institutions that offer certifications in personal training, including the American Council on Exercise (ACE) and the National Academy of Sports Medicine (NASM). However, some people may prefer to work with a coach who has learned personal experience in fitness such as a former athlete, rather than someone who has completed a certification program. In any arrangement, it is important to start smart-

  1. Check with your doctor before beginning a new fitness program

  2. Opt for simple movement patterns at low to moderate weights while you are still learning to limit your risk of injury

  3. Stay hydrated and take rest breaks as needed

  4. Stop exercising if you feel dizzy, lightheaded, nauseated, experience chest pain, or have an unexpectedly difficult time breathing

  5. Don’t do anything you’re not comfortable with

Athletic Trainers

Athletic trainers are clinicians who provide injury preventative services, emergency care, clinical diagnosis of injuries, therapeutic intervention and rehabilitation of both injuries and medical conditions. Athletic training is recognized by the American Medical Association (AMA), Health Resources Services Administration (HRSA) and the Department of Health and Human Services (HHS) as an allied health care profession. As a part of the healthcare system, athletic trainers work under the direction of a physician, and work collaboratively with physical therapists, massage therapists, and chiropractors. As part of an athletic department, they partner with the coaching and strength and conditioning staff, as well as nutrition and sport psychology teams to promote the overall health of the athlete.

Athletic trainers undergo rigorous academic and clinical training, supervised by the Commission on Accreditation of Athletic Training Education (CAATE). The current minimum entry point into the profession of athletic training is at the master’s level. Upon completion of a CAATE-accredited athletic training education program, students become eligible for national certification by successfully completing the Board of Certification, Inc. (BOC) examination. Once certified, athletic trainers are required to complete several hours of continuing education every year in an effort to ensure all professions remain current on the latest recommendations within sports medicine.

Comprehensive Care

There’s not a lot of crossover between the two occupations. This isn’t to say the roles can’t go hand in hand. After working with an athletic trainer to rehabilitate a sprained ankle, for example, an athlete may choose to enlist the help of a personal trainer to return his strength and endurance to the levels they were before the injury.

Physical TheraPT is a multi-faceted clinic, centered on patient success. By placing the individual at the hub of the system, instead of siloing by speciality, we’re able to streamline a truly comprehensive recovery. Our athletes are able to seamlessly work with the professionals they need- physical therapists, athletic trainers, massage therapists, and strength coaches- all in one place. Our athletic trainer offers:

  • Urgent Injury Assessment: Streamline your recovery by seeing an athletic trainer first. With extensive orthopedic education, athletic trainers are able to quickly determine the severity of an injury, determine next-steps and make referrals to local physicians, and provide you with home care instructions

  • Rehab: Apply the same proven approaches used with elite athletes to your unique situation and goals. Our expertise includes post-operative rehab, as well as rehab for both chronic and acute injuries and conditions.

  • Return-to-Play Training: We offer evidence-based programs, utilizing technology like force plates, dynamometer testing, blood flow restriction training (BFR), biofeedback and motion analysis to formulate your plan. Following a comprehensive evaluation, we can problem-solve with you to optimize your movement potential.

  • Injury Prevention: By using similar tools as detailed above, we are able to assess athletes and individuals before an injury occurs. Underlying movement compensations and imbalances are often evident even in healthy athletes. By prescribing corrective exercise strategies, and customized strength and conditioning programming, these vulernabilities can be targeted.

How intense does massage really need to be?

When it comes to massage therapy, many people wonder how intense the pressure needs to be to achieve the best results. There is a common misconception that the deeper and harder the pressure, the more effective the massage. However, the relationship between pressure and therapeutic outcome is more nuanced. Let’s explore the difference between deep pressure and deep tissue massage, why excessive pressure can be counterproductive, and how to find the optimal level of pressure for your needs.

Too Much Pressure?

One key aspect of effective massage therapy is understanding that getting muscles to release isn't about forcing them into submission. When a massage therapist applies pressure, sensory receptors in the skin and muscles send signals to the brain. These signals can help the brain to recognize tension, slowly convincing it to relax the muscles.

While other physiological effects also contribute to reduced tension in the body, putting the brain into a parasympathetic state is key to maximizing the benefits of massage. This means that excessive pressure is actually counterproductive, causing the body to go into a protective mode and tightening up the muscles even more in response to pain or perceived threat. Even worse, too much pressure can cause bruising, inflammation, or further injury.

Finding the Optimal Pressure

The goal of massage therapy is to promote relaxation and facilitate muscle release, not to cause pain. While a certain level of discomfort might be expected, particularly when working on tight or knotted areas, the sensation should be more of a "hurts so good" feeling rather than outright pain.

The optimal pressure during a massage varies from person to person and even from one area of the body to another. What feels good for one person might be too intense or too light for another. The "hurts so good" sensation is often an indicator that the right amount of pressure is being applied. This feeling suggests that the pressure is sufficient to address the muscle tension without causing excessive pain.

Take Control of Your Experience

To get the most out of your massage therapy session, there are several things you can do to help facilitate muscle release:

1. Stay in Communication

Always communicate with your massage therapist about the pressure being applied. No massage therapist, no matter how experienced, can know exactly what you are feeling. Your feedback is essential to ensure the pressure is just right.

2. Avoid Tensing Up

Try to keep your own muscles from tensing during the massage. Tension in the muscles can counteract the effects of the massage and make it harder for the therapist to work effectively.

3. Breathe Deeply

Make sure not to hold your breath. Deep, steady breathing can help to relax your muscles and enhance the therapeutic effects of the massage. When an especially tender or tight area is being worked on, focus on taking deep breaths to help the muscles release.

4. Relax Your Mind

Mental relaxation is just as important as physical relaxation. Try to let go of any stress or anxiety you may be holding onto. A calm mind can help facilitate muscle relaxation.


Effective muscle release involves communicating with the brain through slow and deliberate touch. The right amount of pressure to accomplish this is different from person to person and won’t even be consistent throughout your entire massage. Let go of any preconceived notions about how light or deep a massage needs to be. By finding a balance that promotes relaxation and healing without causing unnecessary pain, and by communicating with your massage therapist, you’ll be surprised at how much more benefit you can get out of each massage!
