If the tendon rupture is a partial tear (without the two parts of the tendon being separated), then non-surgical methods of treatment may suffice. The future of non-surgical care for partial patella tendon ruptures is likely bioengineering. Ligament reconstruction is possible using mesenchymal stem cells and a silk scaffold. [5]
Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [ 1 ] Typically the pain and tenderness is at the lower part of the kneecap , though the upper part may also be affected. [ 2 ]
The most likely time for the patella to shift laterally is during the first 20–30 degrees of flexion as the quadriceps tighten simultaneously and pull the patella laterally. Beyond 30 degrees, the quadriceps tendon and patellar ligament pull the patella posterior into the groove of the knee joint making lateral dislocation of the patella ...
Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [46] More than half (53.5%) of knee dislocations have an associated torn meniscus. [46] Quadriceps tendon rupture occurs up to 13.1% of the time, and patellar tendon rupture occurs 6.8% of the time.

The patella is a floating sesamoid bone held in place by the quadriceps muscle tendon and patellar tendon ligament. Exercises should strengthen quadriceps muscles such as rectus femoris, vastus intermedius, and vastus lateralis. However, tight and strong lateral quadriceps can be an underlying cause of patellar dislocation.

Tendon rupture. Tendon rupture is a condition in which a tendon separates in whole or in part from tissue to which it is attached, or is itself torn or otherwise divided in whole or in part. [1] [2] Examples include: Achilles tendon rupture; Biceps tendon rupture; Anterior cruciate ligament injury; Biceps femoris tendon rupture and Quadriceps ...
Arthrofibrosis can occur after total knee replacement or partial knee replacement, when excessive scar tissue (collagen fibril) deposition occurs in and around the knee. This can be accompanied by shortening of the patellar tendon (patella baja/infera) which can also contribute to limited flexion.
