A patellar dislocation is a knee injury in which the patella (kneecap) slips out of its normal position. [5] Often the knee is partly bent, painful and swollen . [ 1 ] [ 2 ] The patella is also often felt and seen out of place. [ 1 ]
The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place. The knee dislocates towards the outside of the leg, leaving the MPFL torn.

A partial dislocation is referred to as a subluxation. Dislocations are commonly caused by sudden trauma to the joint like during a car accident or fall. A joint dislocation can damage the surrounding ligaments, tendons, muscles, and nerves. [2] Dislocations can occur in any major joint (shoulder, knees, hips) or minor joint (toes, fingers).
Side-to-side movements of the knee should be avoided. The patient is allowed to bear weight as tolerated and should perform quadriceps strengthening exercises along with range of motion exercises. The typical return-to-play time frame for most athletes with a grade III medial knee injury undergoing a rehabilitation program is 5 to 7 weeks.
Australian swimmer Mollie O’Callaghan picked up a knee injury about five weeks ago, described as anything from a dislocation to a simple tweak. The 19-year-old O’Callaghan broke the world ...
Though articular cartilage damage is not life-threatening, it does strongly affect one's quality of life. Articular cartilage damage is often the cause of severe pain, knee swelling, substantial reduction in mobility and severe restrictions to one's activities. Over the last decades, however, research has focused on regenerating damaged joints.
