Dislocation/subluxation of meniscal bearing elements after New Jersey low-contact stress total knee arthroplasty.
From October 1985 to April 1986, 43 consecutive New Jersey low-contact stress total knee arthroplasties (TKAs) were performed for degenerative arthritis of the knee. At the one-year follow-up examination, 91% of the patients had good to excellent results based on the Hospital for Special Surgery scoring system. Four patients, however, sustained dislocation/subluxation of the meniscal bearing elements. Three of these occurred within 13 days postoperatively, and one patient sustained a dislocation at six months postoperatively. These four patients were treated with revision TKA. Despite following the precise technique in performance of this procedure, a 9.3% incidence of dislocation/subluxation of the meniscal bearing elements occurred.
