What's the outcome of knee cap tendon rupture?

Surgery: A rupture of either the quadriceps tendon (above kneecap) or of the patella tendon (below kneecap) are both treated surgical especially if it is a complete tear. These two tendons are critical for proper knee function. They are responsible for straightening the knee.

Surgery required: Complete rupture of the patellar tendon (tendon that connects the knee cap or patella to the tibia) results in loss of ability to extend the knee. This requires surgical intervention by an orthopedic specialist. Recovery can take as long as 6 to 12 months and most patients return to their baseline activities but may experience some residual stiffness.

Mostly good: Most knee cap tendon ruptures heal with return of good range of motion and strength. However, the healing process takes several months. Furthermore, there may be subtle deficits such as a little less bending, slightly less strength, and maybe a little less return of muscle bulk. But what is crystal clear is that the surgical outcomes are significantly better than non-operative care in most patient.
