Abstract:
Unicompartmentat Knee Arthroplasty (UKA) is still considered to be a controversial issue even after three decades of its presence on the Orthopaedic horizon. The initial dismal results of Unicompartmental Knee Arthroplasty and the concurrent excellent results reported by the Total Knee Arthroplasty series are the responsible factors. Currently there has been a renewed interest in UKA because of excellent results reported in the last decade. The recent results of UKA are comparable to Total Knee Arthroplasty (TKA) and are better than High Tibial Osteotomy (HTO). Meticulous patient selection, better implant designs and refined surgical techniques are responsible for the improved results. The procedure is primarily performed for single compartment arthritis which most frequently is medial compartment. Indications and contraindications of the procedure are still evolving. Both fixed and mobile bearing UKA have shown good results. Revision of UKA has not been found as complicated as quoted by the initial reports. Among few questions which still remain unanswered by the current literature are its role in younger patients, optimal implant designs, correct indications /contraindications and the proper surgical technique. Minimally invasive techniques in UKA have shown encouraging early results. Its minimally invasive version is a technically demanding procedure and surgeons not familiar with this technique will benefit from appropriate preoperative instruction. Abstracts of all articles appearing under the heading of Unicompartmental arthroplasty or Unicondylar arthroplasty in Medline were retrieved and reviewed by the primary author; in addition references from major orthopedic and arthroplasty textbooks were obtained. Only relevant papers were included after discussion among the authors.
