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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
