The Benefits of an In-Office Arthroscopy in the Diagnosis of Unresolved Knee Pain

Abstract EN

We report a patient who developed persistent knee pain with mechanical symptoms after an uncomplicated patellofemoral arthroplasty.

The etiology of his knee pain remained inconclusive following magnetic resonance imaging due to metallic artifact image distortion.

With the use of an in-office needle arthroscopy, an immediate and definitive diagnosis was obtained, preventing an unnecessary surgery for a diagnostic arthroscopy.

We discovered a lateral meniscus tear, an anterior cruciate ligament tear, and a medial femoral condyle chondral defect for which the patient underwent arthroscopic partial meniscectomy, ligament reconstruction, and osteochondral allograft transplantation, with resolution of his knee pain.
