Abstract:
BACKGROUND: Unicompartmental knee arthroplasty (UKA) began in the early 1970s, which was once negated due to high postoperative repair rate. The methods for early unicompartment osteoarthritis of the knee include UKA, total knee arthroplasty, high tibial osteotomy and fibular truncation. A large number of retrospective studies and literatures have pointed that UKA is effective for unicompartment osteoarthritis of the knee and holds unique advantages.OBJECTIVE: To review the status and research progress of UKA for anteromedial compartment osteoarthritis of the knee in view of indications, contraindications, operation curve, operation process and main technical points and clinical efficacy.METHODS: The first author retrieved the databases of PubMed and CNKI from March 2006 to September 2016 using the keywords of unicompartmental knee arthroplasty, knee, osteoarthritis, clinical application in English and Chinese,respectively. A total of 95 literatures were searched, and 40 eligible articles were included in accordance with the inclusion criteria.RESULTS AND CONCLUSION: Only unilateral lesion (the degenerative cartilage surface of tibiofemoral joint) is replaced in UKA to treat early unicompartment osteoarthritis of the knee, which exhibits less trauma, rapid recovery, few complications, and normal postoperative proprioception of joint and high patient acceptance. Because of its narrow surgical indications, UKA application has been restricted compared with total knee arthroplasty. Indeed, total knee arthroplasty is matureand, and its long-term curative effect is clear. In contrast, UKA is carried out late in China, has not been popularized, and the long-term clinical efficacy remains to be verified further. But if we can accurately grasp the operation indications, choose appropriate patients, make careful preoperative preparation, and master mature skills, the clinical effect will be satisfactory. With the development of prosthesis, equipment design and operation technology, UKA will be prevailed in the treatment of anteromedial compartment osteoarthritis of the knee.
