Proprioception After Knee Arthroplasty: The Influence of Prosthetic Design

    loading  Checking for direct PDF access through Ovid


It is recognized that awareness of joint position in the knee deteriorates because of aging, anterior cruciate injury, or osteoarthrosis. Proprioception was studied in osteoarthritic and prosthetic knees, including both posterior cruciate ligament (PCL)-retaining and PCL-sacrificing designs. An improvement in proprioception was observed after knee arthroplasty. A PCL-retaining prosthesis was found to confer a greater improvement than a PCL-sacrificing design.
