Get Back in The Groove
When things are “in the groove,” they’re going smoothly. That certainly is the case with your knee. As long as your kneecap (patella) stays in its groove in the knee, you can walk, run, sit, stand and move easily. When the kneecap slips out of the groove, though, problems and pain often result.
Injuries to the knee often include kneecap (patellar) dislocation or subluxation. The patella is a V-shaped bone that sits in a groove in the thighbone. A patellar dislocation occurs when the kneecap is displaced from the thighbone, and the joint surfaces are no longer touching. A subluxation is a similar injury, where the kneecap becomes displaced, but the joint surfaces are still touching. Patellar dislocations and subluxations are most common in adolescents and younger adults.
