膝蓋骨下極骨折偽関節に対する関節鏡視下切除術

Inferior pole fractures of the patella often result from trauma and often affect young, active patients. Most fractures show excellent healing, but nonunion can occur due to tensile forces. Symptomatic nonunion can be treated with open reduction and internal fixation for larger fractures or resection for small fragments. Open resection requires opening of the paratenon and partial patellar tendon release, while arthroscopic removal can be performed in a minimally invasive technique. This Technical Note presents arthroscopic resection as a promising option for carefully selected patients and athletes with refractory patellar nonunion and tendinopathy, as it offers reduced soft tissue disruption and provides functional improvement and significant symptom relief. It is a less invasive alternative to open surgery, providing successful treatment for athletes with high rates of return to sport and former activity level.
