This allows it to glide in the femoral groove, or 'knuckle' of the distal femur. Imprecise movements between the patella and retention the femur cause many cases of anterior knee pain. This problem is referred to as patellofemoral dysfunction or patellofemoral maltracking. The portion of the distal tendon, between the patella and the tibia, is known as the patellar tendon. The patellar tendon can became inflamed or degenerative, a condition known as patellar tendinosis or 'jumpers retention knee'. It is very common in sports such as volleyball and basketball. Posterior to the patellar tendon, within the knee is a collection of fatty tissue known as the infrapatellar fat pad. Age The predominant causes of anterior knee pain vary according to age of the patient. |

The patella sits completely within this distal quadriceps tendon and as such is known as a sesamoid bone. The quadriceps is not a single muscle body modelling but contains several muscles including the rectus femoris, vastus lateralis, vastus intermedius and vastus body modelling medialis obliquus (VMO). The rectus femoris crosses both the hip and the knee, whereas the other muscles cross only the knee. The relevance of this is that the rectus femoris acts as both a knee extensor and body modelling a hip flexor, while the other quadriceps muscles act solely as knee extensors. The large vastus lateralis is active throughout the full range of knee extension but the smaller VMO muscle is active mainly in the last 30° of extension. The patella itself articulates with the distal femur (thigh bone) within the knee. The articulation between the patella and the distal femur is known as the patellofemoral joint. |
