| Abstract |
Unicompartmental knee arthroplasty (UKA) is a safe and well-established treatment for unicompartmental osteoarthritis (OA). Mobile bearing devices promise less polyethylene wear but include the risk of bearing dislocation. We describe two rare cases with an 180° spin in the transversal plane of the mobile bearing and one secondary dislocation. Primary complaints were swelling, discomfort and a short episode of heavy pain. Both cases ended in revision surgery with conversion to a fixed bearing tibial component with good early postoperative results. Symptoms of a 180° spin of the bearing can be subtle, hence in patients with persisting but minor complaints such as swelling and discomfort a carefully radiographic examination is advisable. |
