What is Patella Instability?
Patella instability encompasses recurrent lateral displacement of the patella from the trochlear groove, ranging from subluxation (partial shift) to complete dislocation. Primary episodes often follow trauma; recurrent instability usually involves underlying anatomical risk factors like trochlear dysplasia (shallow groove), patella alta (high-riding patella), increased TT-TG distance, or generalised ligamentous laxity.
The medial patellofemoral ligament (MPFL) is the primary restraint to lateral displacement and is torn in most dislocations. Apprehension, J-sign (lateral deviation on extension), and effusion follow episodes.
Predominantly affecting adolescents and young adults, especially females, it increases cartilage damage and osteoarthritis risk if untreated. At Kinvara Private Hospital, detailed imaging (MRI for soft tissues, CT for bony morphology) classifies contributors, guiding targeted stabilisation from conservative rehabilitation to surgical reconstruction.
Benefits of Treating Patella Instability
- Relief from the recurring pain and swelling that follow each episode of the kneecap slipping or dislocating.
- Restored stability and tracking of the kneecap, allowing safe walking, twisting and pivoting without it giving way.
- Treatment such as MPFL reconstruction lowers the risk of repeat dislocations, cartilage damage and later joint arthritis.
- Greater confidence on stairs, uneven ground and during exercise, removing the constant fear of the knee letting go.
- Reduced reliance on bracing, strapping and activity avoidance to keep the kneecap in place day to day.
- A realistic return to sport and an active lifestyle as strength and patellar control are rebuilt.
