How effective is post-operative rehabilitation for patellar tendon rupture?

The patellar tendon connects the kneecap to the shin and helps the quadriceps straighten the knee. After repair, the knee is commonly protected while the tendon heals. Rehabilitation then uses carefully selected movement, swelling management, thigh-muscle activation, gait practice and later strengthening to rebuild that chain of control.

Progress is not simply about bending the knee as far as possible. The therapist also watches whether the leg can support the body, whether the kneecap and knee move in a controlled way, and whether daily tasks can be completed without a compensating limp.

Keep the brace position, walking instructions and exercise limits set by the surgeon. Use crutches or another aid until the care team confirms that the quadriceps can control the knee safely. Practise the prescribed muscle-setting and movement exercises without forcing the knee, and use the recommended approach for swelling.

Avoid deep squats, sudden lunges, jumping and unapproved resistance while the repair is vulnerable. Tell the therapist about buckling, a persistent limp, difficulty lifting the leg, or pain that changes the way you move so the programme can be adjusted.

Get prompt advice for increasing wound redness, drainage, fever, rapidly worsening swelling, or pain that is not settling. An urgent assessment is needed after a fall, a sudden pop, a new gap around the kneecap, inability to straighten the knee or lift the leg, or a sudden loss of walking control. Chest pain or breathing difficulty needs emergency help.

Ask when the brace angle may change, how much weight-bearing is allowed, which exercises activate the quadriceps safely, and what signs indicate readiness for less support. Ask when stairs, cycling, running or work duties can be considered.
