What is Patella Instability?
Patella instability, also known as patellar subluxation or dislocation, occurs when the kneecap (patella) shifts out of its normal position within the femoral groove. This condition can range from mild subluxation, where the patella partially moves out of place, to full dislocation, where it completely leaves the groove.
Patella instability can result from various factors, including:
Anatomical Factors: Structural abnormalities in the alignment of the knee joint or patella can contribute to instability.
Muscular Imbalances: Weakness or imbalance in the muscles around the knee can affect patellar stability.
Injury or Trauma: A sudden impact, fall, or twisting motion can lead to patella dislocation.
Genetic Predisposition: Some individuals may have a genetic predisposition to patella instability.
What are the symptoms?
Common symptoms of patella instability include:
Pain: Especially when moving the knee or bearing weight on the affected leg.
Swelling: Around the kneecap due to inflammation.
Feeling of Instability: A sensation that the knee may give way or buckle.
Visible Displacement: In more severe cases, the kneecap may visibly shift out of place.
How to Diagnose?
If you have any of the symptoms above, it is advisable to see an orthopaedic specialist for further assessment.
Our doctor will conduct a thorough physical examination, paying attention to the alignment and stability of the patella.
Tests such as the apprehension test and the patellar glide test may be performed to assess the likelihood of patella instability.
The range of motion and any signs of swelling or tenderness will also be evaluated.
What are my Treatment options?
Treatment for patella instability depends on factors such as the severity of the condition and the patient's activity level. If you have any of the symptoms above, it is advisable to see an orthopaedic specialist for further assessment.
The appropriate treatment is decided after assessment and a collaborative discussion based on your needs. They can be broadly divided into conservative (non-surgical) and surgical options.
Conservative Treatment
Conservative Treatment:
Rest, ice, elevation, and physical therapy to improve muscular strength and balance.
Bracing:
Using a knee brace or strap to stabilize the patella and prevent further displacement.
Surgical Treatment
For recurrent or severe cases, surgical procedures like medial patellofemoral ligament (MPFL) reconstruction or tibial tubercle osteotomy may be considered.
