title: Treatment of nonunions about the knee utilizing custom total knee arthroplasty with press-fit intramedullary stems.
abstract: Juxta-articular nonunion about the knee is infrequent but may be a troublesome problem, especially if it is about a total knee arthroplasty or associated with an arthritic joint. This technique of total knee arthroplasty with an uncemented press-fit intramedullary rod and bone grafting achieved union in all nine nonunions about the knee. Radiographic review indicated all nonunions to be healed by an average of 2 months, with none taking longer than 6 months to heal. The average postoperative Hospital for Special Surgery knee score was 78 (range, 50-91), with 4 excellent, 4 good, and 1 poor result. This study demonstrated that this is a successful salvage procedure for juxta-articular nonunions in the face of either arthritis in the adjacent joint, severe articular incongruency, or an ipsilateral total knee arthroplasty.
