Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. [1] Often there is sudden onset of pain and walking is difficult. [1] In a complete rupture, the ability to extend that knee is decreased. [1]
The suprapatellar plica dividing the suprapatellar recess; The infrapatellar plica, in front of the anterior cruciate ligament, reaches from the intercondylar notch to the infrapatellar fat pad; The medial patellar plica, located adjacent to the patella's medial facet, runs vertically along the medial joint capsule
The fat pad is a normal structure but it can sometimes become a problem: It can become damaged and painful; It can be deliberately removed at arthroscopic surgery to make it easier for the surgeon to see what they are doing - but this can also lead to scarring and pain.
Damage to the saphenous nerve and its infrapatellar branch is possible during medial knee surgery, potentially causing numbness or pain over the medial knee and leg. [7] As with all surgeries, there is a risk of bleeding, wound problems, deep vein thrombosis , and infection that can complicate the outcome and rehabilitation process.
UKA surgery may reduce post-operative pain and have a shorter recovery period than a total knee replacement procedure, [1] [2] particularly in people over 75 years of age. [3] Moreover, UKAs may require a smaller incision, less tissue damage, and faster recovery times. [2]
The medial patellofemoral ligament (MPFL) is one of several ligaments on the medial aspect of the knee. It originates in the superomedial aspect of the patella and inserts in the space between the adductor tubercle and the medial femoral epicondyle. The ligament itself extends from the femur to the superomedial patella, and its shape is similar ...
Surgery may be tried if other measures fail. [2] This may involve removal of myxoid degeneration in the tendon. This is reserved for people with severe pain for 6–12 months despite conservative measures. Novel treatment modalities targeting the abnormal blood vessel growth which occurs in the condition are currently being investigated.
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.
