We evaluated 6 patients who underwent MIS-TKA using a lateral approach for valgus knee. There were 4 women (5 knees) and 2 men (2 knees) with a mean age of 71 years. The preoperative diagnoses were osteoarthritis in 3 knees, rheumatoid arthritis in 1 knee, and valgus knee after high tibial osteotomy in 3 knees. The mean JOA score and FTA improved from 48 points and 159 degrees preoperatively, to 80 points and 176 degrees respectively, after a mean follow-up of 16 months. One postoperative complication was mild varus knee deformity due to subsidence of the tibial component in the RA knee at 3 months after surgery. The minimally invasive lateral approach is a useful procedure for the treatment of valgus knee deformity in patients undergoing total knee arthroplasty.
