PHYSICAL THERAPY & REHABILITATION

01 / Understand

What is it?

Rehabilitation is a planned process of restoring strength, movement, confidence and activity capacity. A physical therapist can adapt the plan to the diagnosis, symptoms, goals and any surgical restrictions.

02 / Understand

How is it supposed to work?

Progressive loading, motor control and practice can improve the capacity to perform tasks. Those adaptations are distinct from proof that a torn ligament has structurally healed.

03 / Understand

What does the human evidence show?

The KANON randomized trial compared structured rehabilitation plus early ACL reconstruction with structured rehabilitation and optional delayed reconstruction in young active adults.

At two years, patient-reported KOOS4 improvement was similar between strategies. In the optional-surgery group, 23 of 59 participants later underwent reconstruction. This is evidence for a care strategy in a selected population, not a guarantee that rehabilitation alone works for every ACL injury.

04 / Understand

What outcomes matter?

Pain, function, structural healing, mechanical stability, return to sport, reinjury and long-term outcomes are different measures. Feeling better does not necessarily mean a ligament has reattached or that a knee is ready for cutting and pivoting.

Ask how each relevant outcome will be measured, how long follow-up lasts, and what would count as a meaningful improvement for your activity goals.

Safety, limitations & professional oversight

Progression should reflect individual tolerance and clinical findings. Ongoing giving-way episodes, new swelling or a setback warrant reassessment rather than simply pushing harder.

Rehabilitation is important in both surgical and nonsurgical care. Follow a qualified clinician's restrictions and return-to-sport assessment, not a generic online protocol. Professional licensing varies by location.

Evidence, in context.

These assessments apply only to the named condition and outcome. Evidence strength is not a treatment safety score.

Questions to ask your clinician.

1. What are the progression criteria, and how will strength and instability be assessed?
2. What would trigger a surgical opinion or change in the plan?
3. What is my diagnosis, and which outcome are we trying to improve?
4. What alternatives—including rehabilitation or no procedure—are reasonable for me?
5. What complications should I understand, and how will we monitor progress?
6. What criteria would guide a return to sport, and who will assess them?
