This case involves a sixty-five-year-old male patient who sustained work-related injuries to his right knee. After receiving conservative therapy, the patient underwent arthroscopy and finally a total knee replacement due to painful arthritis. Following the procedure, the patient had complaints of pain and a significantly decreased range of motion compared to before the replacement. X-rays that were taken postoperatively revealed that the patella had not been resurfaced and a revision of the right knee with a downsizing of the prosthesis and recutting of the proximal tibia was recommended. There was some improvement following the revision procedure, however, the patient suffered constant pain in the limb as a result of muscle damage. The substance of the claim was that the prosthetics device utilized by the surgeon during the procedure was improperly sized and that the total knee replacement ultimately failed due to surgical error.
