Patellar subluxation syndrome is an injury involving the kneecap. Patellar subluxation is more common than patellar dislocation and is just as disabling. [1] In this condition, the patella repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint. Patellar subluxation can be ...
The patellofemoral glide, tilt, and grind tests (Clarke's sign), when performed, can provide strong evidence for PFPS. [3] [19] Lastly, lateral instability can be assessed via the patellar apprehension test, which is deemed positive when there is pain or discomfort associated with lateral translation of the patella.
A tangent to the lateral facet of the patella. With the knee in 20° flexed, this angle should normally open laterally. [16] The patellofemoral index is the ratio between the thickness of the medial joint space and the lateral joint space (L). With the knee 20° flexed, it should measure 1.6 or less. [16]
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 ...
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.
The patella plays no significant role in the posterolateral corner. The bony shape of the posterolateral knee, with the two convex opposing surfaces of the lateral femoral condyle and the lateral tibial plateau, makes this portion of the knee inherently unstable compared to the medial aspect. Thus, it has a much higher risk of not healing ...
A patella alta is a high-riding (superiorly aligned) patella. An attenuated patella alta is an unusually small patella that develops out of and above the joint. A patella baja is a low-riding patella. A long-standing patella baja may result in extensor dysfunction. [5] Insall-Salvati ratio (A divided by B). [6]
Lateral pelvic tilt describes tilting toward either right or left and is associated with scoliosis or people who have legs of different length. It can also happen when one leg is bent while the other remains straight, in that case the bent side's hip can follow the femur as knee lowers towards the ground.
