ACL Reconstruction Recovery: Complete Timeline and Rehabilitation Guide

A comprehensive guide to ACL reconstruction recovery, covering each phase of rehabilitation from surgery to return to sport. Expert advice from Actilife Physiotherapy.

Understanding ACL Reconstruction

ACL reconstruction is a surgical procedure where the torn anterior cruciate ligament is replaced with a graft, typically from the patellar tendon, hamstring tendon, or quadriceps tendon. The surgery is performed arthroscopically and is followed by a structured rehabilitation program that typically spans 9-12 months.

Phase 1: Prehabilitation (Before Surgery)

Prehabilitation involves strengthening the muscles around the knee before surgery. Patients who complete prehabilitation typically achieve better outcomes and faster recovery. Focus on quadriceps strengthening, hamstring flexibility, and pain-free range of motion exercises.

Phase 2: Immediate Post-Operative (0-2 Weeks)

This phase focuses on pain and swelling management, regaining full knee extension, and activating the quadriceps muscle. Patients will use crutches and a brace during this period. Goals include achieving 0 degrees of extension and 90 degrees of flexion.

Phase 3: Recovery (2-6 Weeks)

As swelling decreases and range of motion improves, patients transition to closed-chain exercises. Goals include weaning off crutches, normalizing gait, and maintaining full range of motion. Stationary cycling and gentle strengthening begin.

Phase 4: Strengthening (6 Weeks - 4 Months)

Progressive strengthening exercises begin in earnest. This includes squats, lunges, step-ups, and hamstring curls. Balance and proprioception training are introduced. Goals include symmetrical strength and normal neuromuscular control.

Phase 5: Advanced Training (4-6 Months)

Running is typically introduced around 4-5 months. Agility drills, plyometrics, and sport-specific training begin under careful supervision. Goals include achieving 90% strength symmetry and passing functional tests.

Phase 6: Return to Sport (6-12 Months)

The final phase focuses on return-to-sport testing, including hop tests, strength testing, and sport-specific assessments. Most athletes return to competitive sports between 9-12 months post-surgery.
