What are the treatment options for quadriceps tendon rupture?

The quadriceps tendon connects the thigh muscles to the kneecap and helps straighten the knee. A complete rupture can make straight-leg lifting or active knee extension difficult. Examination and imaging help clarify whether the tendon is fully or partly torn, where it is injured and how much function remains. A partial tear with preserved extension may sometimes be managed with bracing, activity restriction and close review.

A complete tear or a partial tear with major functional loss may need tendon repair surgery to restore continuity. After repair, the knee is protected while the tendon heals, then movement and strength are advanced in stages. The exact brace settings, weight-bearing instructions and exercise timing must come from the treating surgeon and rehabilitation team.

Until assessed, avoid forceful bending, jumping and pushing through a weak knee. Use the support and walking method prescribed, and do not drive or return to sport until your clinician confirms that control is adequate. After surgery, attend post-operative rehabilitation and report increasing wound drainage, calf swelling, new numbness or pain that is difficult to control. Progress is guided by healing and knee control rather than by a fixed timetable.

Seek prompt assessment after a sudden pop followed by loss of knee extension, a deep knee deformity or inability to walk safely. After surgery, urgent help is needed for chest pain, breathlessness, a very swollen painful calf, fever, spreading redness or wound discharge. Do not wait for a routine appointment when these symptoms appear.

Is my tear partial or complete, and how is that confirmed? Can my current knee extension be restored without surgery? If repair is advised, what protection and rehabilitation will I need? When can I safely walk, work or drive?
