Medial patellar instability (MPI) is a known sequela of previous lateral retinacular release. Literature on surgical intervention is scarce. We present a case of a 35-year-old woman with hypermobility type Ehlers-Danlos syndrome, with bilateral iatrogenic MPI (IMPI) and lateral patellar instability. This condition led to a marked decrease in quality of life, 10/10 persistent pain, and frequent dislocation events. She was successfully treated surgically, and at 2 years had 0/10 pain and no further dislocations.
Our technique for medial and lateral patellofemoral ligament reconstruction is a viable intervention for patients with IMPI, even in the setting of underlying collagen disorder.
