Rehabilitation and Return to Play
Core concepts
Understand phased rehabilitation, criteria-based progression, strength and power testing, proprioception, neuromuscular control, workload management, and sport-specific return-to-play testing. Rehabilitation should progress from pain control and protected motion to strength, plyometrics, and sport-specific skills. Return decisions combine tissue healing, clinical examination, functional testing, and psychological readiness. In ACL reconstruction, quadriceps and hamstring strength symmetry, hop tests, and movement quality matter. Concussion return follows a graduated symptom-limited protocol. Tendinopathy management emphasizes progressive loading rather than complete rest.
Traps
Time since surgery alone is not a return-to-play criterion. Do not clear an athlete with persistent swelling, instability, or less than 90% limb symmetry on strength or functional tests. In children, growth and physeal status alter rehabilitation and return timelines. Overreliance on passive modalities delays active recovery. Returning too soon after concussion or ACL reconstruction increases re-injury risk.
Worked example
A 20-year-old soccer player is 10 months after ACL reconstruction with full motion and no effusion. Rule of thumb: return-to-sport testing should include quadriceps and hamstring limb symmetry above 90%, hop-test symmetry, and sport-specific cutting and deceleration without pain or apprehension. Passing strength alone is not enough; the athlete must also demonstrate confident, controlled movement under fatigue.
