Effectiveness of a Digital Prehabilitation Programme Compared With Usual Care in Patients Awaiting Anterior Cruciate Ligament Reconstruction: A Randomised Controlled Superiority Trial

Background Prehabilitation prior to anterior cruciate ligament reconstruction (ACLR) has been shown to improve preoperative knee function, enhance quadriceps strength, and optimize postoperative recovery. However, access to supervised prehabilitation programmes remains limited. Digital health interventions may improve accessibility, adherence, and continuity of care.

Objective To determine whether a structured digital prehabilitation programme is more effective than usual care in improving quadriceps strength and functional outcomes after ACL reconstruction.

Methods/design This study is a single-centre, parallel-group, assessor-blinded randomised controlled trial. Adult participants scheduled for primary ACL reconstruction will be randomly allocated to either a usual care group or a digital prehabilitation group. The intervention group will complete a 4-week structured digital prehabilitation programme prior to surgery. Outcomes will be assessed preoperatively and up to 12 weeks postoperatively.

Expected Results The digital prehabilitation programme is expected to improve preoperative knee status and enhance postoperative quadriceps strength and functional recovery compared to usual care.
