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 ...
The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau. On the medial femoral condyle there are three bony landmarks that are important: the medial epicondyle, adductor tubercle, and gastrocnemius tubercle. The medial epicondyle is the most distal and anterior prominence.
On a normal radiograph, the line intersects the inferior pole of the patella, and so can be useful in diagnosing a broken femur as well as a patellar tendon rupture. It also helps to define "Schottle point" intra-operatively for reconstruction of MPFL(Medial patello-femoral ligament.) [3] It may also be used to describe the course of an ACL graft.
Displacement of the patella laterally out of its groove strains the medial stabilizing connective tissues, particularly the medial patellofemoral ligament (supporting 50–80% of the knee mechanisms in lateral patellar glide), which is torn usually at its femoral attachment. [3] Traumatic patellar dislocation may cause bleeding into the joint ...
The unicompartmental replacement is a minimally invasive option for people whose arthritis is isolated to either the medial or the lateral compartment. The procedure offers several benefits for patients with a moderately active lifestyle, who have arthritis in just one knee compartment, and who are within normal weight ranges.
The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol.
CT angiogram 3D reconstruction, posterior view showing a normal artery on the left, and occlusion to right popliteal artery as a result of a knee dislocation [10] Symptoms include knee pain. [2] The joint may also have lost its normal shape and contour. [2] A joint effusion may, or may not, be present. [2]
The patient's chondrocytes are removed arthroscopically from a non load-bearing area from either the intercondylar notch or the superior ridge of the medial or lateral femoral condyles. 10,000 cells are harvested and grown in vitro for approximately six weeks until the population reaches 10-12 million cells. Then these cells are seeded onto a ...
