ACL Injury: The Road Back to Sport, Stage by Stage
Whether you have surgery or not, the rehab you do decides how well your knee works. Here's what each stage involves.
An anterior cruciate ligament (ACL) injury usually happens when you twist, land awkwardly or change direction suddenly. Many people hear a pop, then the knee swells within hours. The good news: with a structured programme, most people get back to an active life, and many to their sport.
Stage 1: Calm the knee (weeks 0–2)
Control the swelling, get the knee fully straight, and wake up the thigh muscle. Walking with support is usually allowed early. If you are having surgery, this stage happens both before and after the operation.
Stage 2: Build strength (weeks 2–12)
Gradually loaded strength work for the quadriceps, hamstrings, hips and calf, plus balance training. Cycling and controlled squats come in as the knee allows.
Stage 3: Running and agility (around months 3–6)
Once strength and control are good, we start straight-line running, then hopping, cutting and landing drills. This stage is about trusting the knee again.
Stage 4: Return to sport (around months 6–9+)
Sport-specific training and objective tests of strength and hopping compared with the other leg. Returning too early is the biggest risk for re-injury, so we test before we clear you, not just count weeks.
Do I need surgery?
Not always. It depends on your age, your sport, any meniscus damage and how stable the knee feels. We work with your orthopaedic surgeon and help you make an informed decision.
