Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage.
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.
Chondromalacia patellae is a term sometimes used synonymously with PFPS. [7] However, there is general consensus that PFPS applies only to individuals without cartilage damage, [ 7 ] thereby distinguishing it from chondromalacia patellae, a condition with softening of the patellar articular cartilage.

The most common location of plica tissue is along the medial (inside) side of the knee. The plica can tether the patella to the femur, be located between the femur and patella, or be located along the femoral condyle. If the plica tethers the patella to the femoral condyle, the symptoms may cause it to be mistaken for chondromalacia.

The medial condyle is larger than the lateral (outer) condyle due to more weight bearing caused by the centre of mass being medial to the knee. On the posterior surface of the condyle the linea aspera (a ridge with two lips: medial and lateral; running down the posterior shaft of the femur) turns into the medial and lateral supracondylar ridges ...
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
There are four compartments to the knee. These are the medial and lateral tibiofemoral compartments, the patellofemoral compartment and the superior tibiofibular joint. The components of each of these compartments can experience repetitive strain, injury or disease. [1]
