Acute Irreducible Rotational Patellar Dislocation with Patellar Tendon Rupture: A Case Report

JBJS Case Connect. 2023 Aug 17;13(3). doi: 10.2106/JBJS.CC.23.00058. eCollection 2023 Jul 1.

Abstract

Case: In this report, we present a case of acute patellar dislocation with both vertical and longitudinal rotation of the patella. As a result of rotation in the longitudinal axis, the articular surface of the patella faced outward, and the dorsal surface faced the femoral condyle. The patient underwent open reduction. One year after open reduction and soft-tissue repair, the patient had acceptable knee function and no knee pain.

Conclusion: This case shows how similar cases may be treated with an open reduction to properly address the patellar dislocation.
