The kneecap, also known as the patella, smoothly moves over a groove at the end of the thighbone (femur) during the bending or straightening of the leg.
However, this process can be disrupted if the kneecap becomes misaligned or dislocates, leading to instability. This often occurs when the body turns but the foot remains firmly planted, a common scenario in sports or dancing. Direct impact from a fall or contact sport can also cause this condition.
Recognising the Symptoms of Patellar Dislocation
Experiencing knee pain, a sensation of the knee 'giving way' during walking, stiffness, swelling, and a cracking sound while moving the knee are typical signs of patellar dislocation and instability.
Diagnosis of Patellar Dislocation
To diagnose patellar dislocation, a physical examination is generally sufficient. However, in some cases, additional imaging tests like X-rays and MRI scans may be necessary to confirm the diagnosis and assess the extent of the condition.
Effective Treatment Options for Patellar Dislocation
The initial approach to treating patellar dislocation and instability usually involves non-surgical methods. This can include physical therapy to strengthen the muscles around the knee and wearing a brace for support. In more severe cases, or if dislocations recur, surgical intervention might be needed. Surgical treatments aim to realign the bones or tighten the tendons to secure the kneecap in its proper position.
