What to expect from knee bracing for a PCL injury

The posterior cruciate ligament helps stop the shinbone from moving too far backward beneath the thighbone. A specialised brace is designed to apply support in the opposite direction and may be used when standing or walking. The appropriate design and wearing schedule depend on whether other knee structures are injured, how stable the knee is, and what your examination shows.

Have the brace fitted and learn how to check its position after sitting, standing, and walking. Keep straps snug but watch for numbness, skin irritation, or increasing pain. Follow the prescribed loading and exercise plan. Early rehabilitation may emphasise safe motion and quadriceps control, while later work builds strength, balance, and confidence for daily tasks.

Contact your care team if the knee becomes more unstable, swelling escalates, or you lose the ability to bear weight. Seek urgent help for a cold or discoloured foot, new weakness or numbness, severe calf pain or swelling, chest pain, or sudden breathlessness. Do not continue using a painful or damaged brace without advice.

Ask what movements the brace is intended to limit, whether it should be worn at night, and how to manage stairs. Clarify weight-bearing limits, exercise progression, driving guidance, and the signs that indicate the brace needs refitting.
