ACL Surgery Pain: Can Supervised Rehabilitation Help?

Can supervised rehabilitation help persistent pain after ACL surgery?

The trial, published in Annals of Internal Medicine, compared supervised rehabilitation with a single education session and resources for independent exercise. At four months, the supervised group reported better knee outcomes and showed greater thigh muscle strength. By 12 months, the advantage had narrowed, according to the [American College of Physicians trial summary](https://www.eurekalert.org/news-releases/1144945).

The SUPER-Knee study addressed a specific recovery gap: participants still had symptoms nine to 36 months after reconstruction. Its findings concern people whose recovery remains incomplete well beyond the initial postoperative period. The trial's main questionnaire combined pain, other symptoms, sports function and knee-related quality of life, providing a broader assessment than pain alone. The eligibility criteria and outcome measures appear in the [published study protocol](https://pmc.ncbi.nlm.nih.gov/articles/PMC9853250/).

What does supervised ACL rehabilitation involve?

The protocol specified an initial four-month program with two supervised sessions each week, supplemented by independent exercise. Therapists tailored exercise selection and progression to participants' goals and abilities. Education addressed exercise habits, expectations, pain and fear of movement. The later phase emphasized independent training with occasional follow-up sessions. These details describe the planned intervention, rather than how many sessions every participant actually completed. [SUPER-Knee protocol](https://pmc.ncbi.nlm.nih.gov/articles/PMC9853250/)

This was a comparison of treatment packages, so the findings cannot isolate the contribution of supervision from exercise progression, education or additional professional contact. Participants also knew which treatment they received, creating potential for expectations to influence questionnaire responses. That limitation, acknowledged in the protocol, matters when interpreting reported improvements, even in a randomized trial.

Should everyone with pain after ACL reconstruction restart physiotherapy?

The Aspetar rehabilitation guideline identifies exercise as the foundation of recovery and recommends combining strength work with training that improves movement control. It also recognizes independently performed rehabilitation as an option when programs are individually prescribed and monitored. Earlier comparisons did not consistently favor supervision, and evidence for many rehabilitation decisions remains uncertain. The new trial therefore adds evidence for a particular group with persistent symptoms. [Aspetar clinical practice guideline](https://bjsm.bmj.com/content/57/9/500)

The trial found no between-group difference in cartilage thickness. That does not establish that rehabilitation prevents osteoarthritis or rebuilds cartilage; symptom improvement and structural joint changes are separate outcomes. Its clearest implication is that further rehabilitation may improve recovery even after symptoms have persisted for months. The smaller difference at one year also leaves questions about maintaining an early advantage. [ACP report on the trial](https://www.eurekalert.org/news-releases/1144945)
