What to expect from tendon repair surgery for quadriceps tendon rupture

The quadriceps tendon helps straighten the knee. During repair, the surgeon exposes the tear, prepares the tendon and secures it to the upper kneecap with sutures or fixation devices. The knee may be placed in a brace that limits bending while the repair heals. Early discomfort, swelling and weakness are expected, and the operated leg may need crutches.

Progress depends on the tear, tissue quality, your general health and the surgeon’s protocol. Physiotherapy usually begins with safe muscle activation and gradually introduces knee movement, walking control and strengthening. Returning to demanding sport or work takes longer than becoming comfortable with daily activities.

Before surgery, arrange transport, help at home and a clear route through your home. Follow instructions about fasting and medicines, including whether any blood-thinning medicine should be paused. Afterward, keep the brace and wound dressing exactly as instructed, use crutches as taught, elevate the leg for swelling and complete only the exercises approved by your physiotherapist. Do not force knee bending or test the repair by lifting heavily.

Attend wound checks and physiotherapy appointments. Tell the team if pain prevents sleep or exercises, because the plan may need adjustment rather than extra effort.

Contact your surgical team promptly for increasing redness, warmth, drainage, wound opening, fever, or pain that is worsening instead of settling. Seek urgent help for sudden chest pain, trouble breathing, faintness, or a new swollen and painful calf. A sudden loss of the ability to straighten the knee or a fall that sharply increases pain also needs prompt assessment.

Ask which tendon fixation was used, how much weight and knee bending are allowed, when the brace may be adjusted, and what signs suggest the repair is under strain. Clarify when driving, work, stairs and sport may be resumed, and who to contact outside clinic hours.
