An unstable kneecap refers to a condition where the patella (kneecap) becomes displaced from its normal position within the femoral groove, causing a range of issues including pain and mobility problems that may require medical attention.
Symptoms of an unstable kneecap may include:
For partial dislocations of the kneecap, exercise-based treatments and bracing may be prescribed. These activities help strengthen the muscles around the thigh, providing support to stabilise the knee in its correct alignment. Physical therapists may recommend cycling in conjunction with the use of a stabilising brace to facilitate a faster recovery. Most patients can anticipate a return to normal activities within one to three months after treatment.
In cases of complete kneecap dislocation, reduction – getting the kneecap back into its proper position – is the first step. This can sometimes happen naturally, or a doctor may gently guide it back in place. If instability persists and becomes a chronic issue, surgery may be necessary.
In the event that instability persists and becomes a chronic condition, patients may require surgical intervention to regain full mobility. Surgical interventions can realign and tighten tendons to ensure the kneecap remains in its proper position or address any obstructing tissues. Knee arthroscopy, a common surgical technique used to treat an unstable kneecap, is detailed below.
Arthroscopy is a minimally invasive procedure used by doctors to both diagnose and treat joint pain without resorting to major surgery. Through small incisions, slender instruments are inserted, allowing for visual examination and targeted interventions within the joint. This procedure aims to reduce pain, increase mobility, and facilitate a swift return to regular activities.
