How long does post-operative rehabilitation take to work for patellar tendon rupture?

The repaired tendon needs protection while it reconnects securely to the kneecap. Early care may focus on keeping the knee within a permitted range, controlling swelling, and walking with the support advised by your team. Later stages can add gentle movement, progressive muscle work, balance practice, and tasks that resemble your daily activities.

Progress is not measured only by pain. Your clinician may also check knee bending, the ability to straighten the knee, quadriceps control, walking pattern, and whether the repair remains stable. Stiffness or weakness can remain after pain has settled, so increasing activity should follow the prescribed milestones.

Follow the brace, weight-bearing, and exercise instructions exactly, because doing more than the repair can tolerate may set progress back. Keep scheduled physiotherapy appointments and report exercises that cause sharp pain, new swelling, or a loss of control. Use the agreed method for stairs and transfers, and prepare your home so that essential items are easy to reach.

Ask when driving, work duties, cycling, kneeling, and sport-specific training can be reconsidered. The answer depends on examination findings rather than a calendar date.

Contact your surgical team urgently for a sudden inability to straighten the knee, a new giving-way feeling, a snap followed by worsening pain, rapidly increasing swelling, wound drainage, fever, or redness spreading around the incision. Seek emergency help for chest pain, severe breathlessness, or a newly swollen painful calf.

Ask which knee movements and weight-bearing limits apply now, what improvement should be visible at the next review, and which symptoms mean the repair needs checking. You can also ask how the rehabilitation plan will change if stiffness or quadriceps weakness persists.
