What Tests Should I Pass Before Returning to Sport After ACL Surgery?
Updated: Sep 5
Return-to-sport testing helps identify whether important physical and psychological deficits remain. This article explains what may be contributing, what to monitor and how rehabilitation can address it without relying on a one-size-fits-all timeline.
A useful assessment considers strength, hop and jump performance, movement quality, running mechanics, symptoms and psychological readiness. The exact priorities depend on graft choice, whether there were additional procedures such as meniscal repair, the surgeon’s restrictions, the stage of rehabilitation and the activities you want to return to.
It is also important to look at the knee’s response over the following 24 hours. A session that looks fine at the time may still have been too much if swelling, pain, stiffness or movement quality are clearly worse later that day or the next morning.
Rehabilitation usually combines progressive strength work with restoration of knee movement, gait and single-leg control. As capacity improves, exercises can become heavier, faster and more specific to running, jumping, landing, deceleration and sport. Progression should be earned through good response and objective improvement rather than rushed to meet an arbitrary week.
Return to sport should be criteria-based. Strength, jumping and running performance, movement quality, symptoms, sport-specific exposure and psychological readiness all matter. A calendar date on its own cannot show that the knee is ready for unrestricted sport.
Consistency matters more than trying to complete a huge amount in one session. Follow the programme you have been given, record swelling and pain responses, and note whether walking, stairs or training feel easier over time. If an exercise repeatedly causes a marked increase in swelling or loss of movement, the dose or exercise selection may need adjusting.
When should you get the knee reviewed?
Seek clinical review if you develop a new episode of giving way, a locked knee, rapidly increasing swelling, worsening loss of movement, significant calf pain or swelling, wound concerns, fever, or a substantial deterioration that does not settle. Sudden chest pain or shortness of breath requires urgent medical assessment.
