RESUMO
BACKGROUND: Unicompartmental knee arthroplasty (UKA) has been widely applied in the treatment of anterior-medial osteoarthritis of the knee and is widely recognized as one of the most effective treatments.OBJECTIVE: To explore the short-term efficacy of UKA for anterior-medial unicompartmental knee osteoarthritis. METHODS: Clinical data of 42 patients (48 knees) with anterior-medial unicompartmental knee osteoarthritis undergoing UKA in Heping Hospital Affiliated to Changzhi Medical College from May 2014 to May 2016 were analyzed retrospectively. The preoperative and postoperative last follow-up Hospital for Special Surgery, the Knee Society Score, Western Ontario and Macmaster scores, as well as the range of motion of the knee were compared through clinic reexamination or telephones to evaluate the short-term efficacy. RESULTS AND CONCLUSION: (1) The follow-up time was 6-24 months. (2) The pain of the medial knee joint was relieved in different degrees, and there were significant differences in the Hospital for Special Surgery, the Knee Society Score, Western Ontario and Macmaster scores, as well as the range of motion of the knee between preoperation and postoperation (P < 0.05). (3) No lower limb deep vein thrombosis, pulmonary embolism, infection, meniscus dislocation or prosthesis loosening occurred. (4) To conclude, UKA exhibits less trauma, rapid recovery and less complications in the treatment of anterior-medial unicompartmental knee osteoarthritis, which obtains good short-term efficacy, and its long-term efficacy needs to be studied in depth.
