Knee Brace After Ligament Surgery: ROM Brace, Immobiliser or Functional Support?
Short answer: After ligament surgery such as ACL reconstruction, surgeons usually prescribe a hinged ROM (range-of-motion) knee brace or a knee immobiliser for the first weeks. Later in rehab they move to a functional hinged knee support for return to activity. The right brace, how long to wear it and the angle it is locked at are set by your surgeon or physiotherapist. Use this guide to understand the options, not to replace their instructions.
Braces by recovery stage
| Stage | Typical brace | Purpose |
|---|---|---|
| Immediately after surgery | Knee immobiliser (long, 19–22") or ROM brace locked in extension | Protect the graft and hold the knee straight |
| Early rehab | ROM brace with the flexion angle increased step by step | Allow controlled bending while protecting the repair |
| Return to activity | Functional hinged knee support | Side-to-side stability during sport and daily activity |
| Mild swelling or confidence | Elastic or neoprene knee sleeve | Compression and warmth; not for protecting a graft |

Getting the size right
- Measure thigh and calf circumference at the points shown on the product size chart, with the leg relaxed.
- Swelling changes after surgery; recheck the fit and strap tension after the first 1–2 weeks.
- A brace that slips down usually means it is too loose or is placed with the hinge off-centre. Align the hinges with the knee joint line.
When to call your doctor
Contact your surgeon promptly for increasing calf pain or swelling, numbness or colour change in the foot, fever, or a wound that is red or discharging. Do not unlock or change the brace angle without advice.
FAQ
How long do you wear a brace after ACL surgery? It varies by surgeon and technique, often a few weeks. Some protocols use no brace at all. Follow your surgeon's plan.
Immobiliser or ROM brace? An immobiliser keeps the knee straight. A ROM brace can be locked straight and later set to allow a chosen bending range, so it serves more of the recovery.
