Pj. Warren et al., PROPRIOCEPTION AFTER KNEE ARTHROPLASTY - THE INFLUENCE OF PROSTHETIC DESIGN, Clinical orthopaedics and related research, (297), 1993, pp. 182-187
It is recognized that awareness of joint position in the knee deterior
ates because of aging, anterior cruciate injury, or osteoarthrosis. Pr
oprioception was studied in osteoarthritic and prosthetic knees, inclu
ding both posterior cruciate ligament (PCL)-retaining and PCL-sacrific
ing 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.
