Total Knee Arthroplasty with Lateral Femoral Epicondylar Osteotomy in a Knee with Severe Extra-Articular Varus: A Case-Report.

CASE: A 60-year-old woman presented 18 years following a conservatively managed right tibial proximal metaphyseal fracture, with knee osteoarthritis and an extra-articular tibial varus deformity. During total knee arthroplasty, excessive lateral laxity was noted in both extension and flexion. Lateral femoral epicondylar osteotomy (LFEO) was performed; the bone block was duly transported and secured. Optimal gap balance was attained. The osteotomy site showed radiologic union 6 months postoperatively. At the 3-year follow-up, her Knee Society Score and functional score were 92 and 90, respectively.

CONCLUSION

LFEO is a valuable tool for arthroplasty surgeons and can result in good outcomes.
