Medial Patellofemoral Ligament Reconstruction in Osteogenesis Imperfecta Using Modified Basket-Weave Technique: A Case Report.

CASE: A 14-year-old adolescent girl with osteogenesis imperfecta presented with bilateral patellar instability. Examination showed subluxation (confirmed on imaging) with flexion >60° (left). Surgical treatment consisted of lateral retinacular lengthening, quadriceps realignment and lengthening, and medial patellofemoral ligament (MPFL) reconstruction with semitendinosus allograft using an all-suture anchor for femoral fixation and a basket-weave technique to secure the graft to the anterior patellar periosteum. At 1-year follow-up, she demonstrated central patellar tracking without extensor lag.

CONCLUSION

Avoiding patellar bone tunneling with basket-weave soft-tissue fixation during MPFL reconstruction may enable typical postoperative rehabilitation with reduced risk of patella fracture in patients with OI.
