“…Eight case series included in our study concerned distal femoral osteotomy as an additional procedure to TKA [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ] ( Table 1 ). Five of them presented one-stage total knee arthroplasty with distal femoral osteotomy for the correction of extra-articular deformity with good results in the last follow-up (4 to 10 years of follow-up) [ 19 , 20 , 21 , 22 , 25 ]. Five of them included post-traumatic patients with femoral fractures malunion (in total, 19 patients) [ 19 , 20 , 21 , 22 , 25 ]: constitutional in three patients, secondary after femoral osteotomy with overcorrection in three patients [ 22 ], and one with hypophosphatemic rickets [ 25 ].…”
