Do all ACL tears need surgery?
No — and a surgeon who says otherwise is not being straight with you. The decision depends on your knee and your life:
- Physiotherapy alone can work for low-demand patients with stable knees
- Reconstruction is recommended for athletes, active patients, and anyone whose knee gives way repeatedly
- Delaying surgery in an unstable knee risks meniscus and cartilage damage — the real long-term cost
How the surgery works
ACL reconstruction is done arthroscopically — through keyhole incisions with a camera. The torn ligament is replaced with a graft (commonly hamstring or peroneus tendon; graft choice is matched to your sport and anatomy). Meniscus tears found during surgery are repaired in the same sitting. Most patients walk the same or next day and go home within 24 hours.
Return to sport: the honest timeline
- Week 0–2: walking with support, gentle range-of-motion exercises
- Week 2–6: full weight-bearing, stationary cycling, strengthening
- Month 3: straight-line jogging
- Month 6: sport-specific drills after strength testing
- Month 8–12: full competitive return once hop and strength tests pass — rushing this is the main cause of re-tears
