Patella Dislocations
The patella (knee cap) sits inside the quadriceps tendon and slides up and down in a bony groove (trochlea) in the femur to assist in knee extension, climbing stairs, and squatting. When the patella slips out of this groove, it is called a patella dislocation. It is a highly painful condition and often requires surgical correction to prevent it from becoming recurrent.
Patellar Instability Treatments
MPFL Reconstruction
Medial Patellofemoral LigamentThe MPFL is the primary stabilizer that holds the patella inside its groove. When it ruptures, we perform an anatomical reconstruction using a hamstring tendon graft secured with bio-screws.
Tibial Tuberosity Transfer
Realignment of Patella TendonFor patients with a high-riding patella (patella alta) or an outward pull of the tendon (increased TT:TG distance), the attachment bone (tibial tuberosity) is shifted to redirect the alignment.
Trochleoplasty
Deepening the Femoral GrooveA shallow femoral groove (trochlear dysplasia) makes it easy for the knee cap to slip. Trochleoplasty is a specialized bony surgery that deepens the groove to stabilize the patella.
Stabilize Your Knee Cap
Book a consultation with Dr. Yugal Varandani to thoroughly evaluate your patellar instability using X-ray/MRI and develop a precise surgical realignment plan.
