A Comprehensive Rehabilitation Program with Quadriceps Strengthening in Closed versus Open Kinetic Chain Exercise in Patients with Anterior Cruciate Ligament Deficiency

Abstract

Rehabilitation with OKC quadriceps exercise led to significantly greater quadriceps strength compared with rehabilitation with CKC quadriceps exercise. Hamstring strength, static and dynamic translation, and functional outcome were similar between groups. Patients with ACL deficiency may need OKC quadriceps strengthening to regain good muscle torque.
