Return-to-sport criteria
Quick answer
Return-to-sport criteria are a set of tests and milestones, covering strength, hopping, movement quality, knee stability and confidence, that show when a knee is ready for training and competition again. Doha knee surgeon Dr. Pablo Gelber at Aman Hospital uses them alongside time since surgery, rather than the calendar alone.
What they are
There is no single test. A typical return-to-sport assessment after ACL reconstruction may include:
- Quadriceps and hamstring strength compared with the other leg, often aiming for at least about 90 percent
- Single-leg hop tests for distance and control
- Agility, cutting and landing assessed for technique
- No swelling, full movement and a stable knee on examination
- A psychological readiness questionnaire
Why they matter for patients
Research shows that athletes who return to pivoting sport early, or before meeting objective criteria, have a higher risk of re-injury. Waiting until at least around nine months after ACL reconstruction and passing testing are both linked with lower risk.
Criteria also help after meniscus repair, cartilage surgery and kneecap stabilisation, though the specific targets differ.
How testing works
Testing is usually done by a physiotherapist, sometimes with strength-measuring equipment. Return is staged: training without contact, then full training, then matches. Footballers, padel players and basketball players in Doha follow sport-specific drills. Failing a test is not a setback; it shows what to work on next.
Frequently asked questions
My knee feels fine. Why can I not play yet?
A knee can feel normal long before the graft and muscles are ready for cutting and landing. Objective tests often reveal strength gaps that feeling alone does not.
Do I need a brace when I go back to sport?
Most athletes do not need one after a successful reconstruction and good rehabilitation. Some prefer it for confidence, which can be discussed individually.
