When everything is working normally, the kneecap (patella) moves smoothly up and down within a groove at the end of the thighbone called the trochlea. This smooth movement allows you to walk, run, sit, squat, and climb stairs comfortably.
When the kneecap slips out of this groove, it can cause pain, swelling, and instability. If this happens repeatedly, the condition is called recurrent patellar instability.
The patella sits at the front of the knee and connects the thigh muscles (quadriceps) to the shinbone (tibia). As the knee bends and straightens, the kneecap glides within the trochlear groove.
Several structures keep the patella aligned:
