What Is the First Treatment for a PCL Injury?

The posterior cruciate ligament helps limit backward movement of the shin relative to the thigh. Treatment depends on whether the injury is partial or complete and whether other knee structures were affected. A brace can support the knee while swelling and pain settle and can limit positions that strain the healing ligament.

Physiotherapy usually progresses from comfortable movement and swelling control to quadriceps strengthening, balance, and functional tasks. The clinician may adjust the plan according to stability, walking pattern, work demands, and sport.

Follow the brace and weight-bearing instructions given after examination. Avoid pivoting, kneeling, sudden deceleration, and contact activity until cleared. Ice wrapped in cloth and elevation may help a swollen knee, while repeated deep bending can aggravate symptoms in the early phase.

Keep follow-up appointments so the team can check stability and progress exercises safely. Some isolated injuries respond well to non-surgical care; persistent instability, combined ligament damage, or high functional demands may require a different discussion.

Seek urgent assessment if the knee is visibly deformed, rapidly swelling, locked, or impossible to bear weight on. New numbness, a cold foot, severe pain, or a worsening sense that the leg is giving way also needs prompt review.

Is the PCL injury isolated? How should I use the brace and load the leg? Which exercises are safe now, and what signs show that rehabilitation is progressing?
