Medial Displacement Calcaneal Osteotomy for Unilateral Adult Acquired Flatfoot: Effects of Minimally Invasive Surgery on Pain, Alignment, Functioning, and Quality of Life

We aimed to assess the effects of medial displacement calcaneal osteotomy (MDCO) through a minimal skin inci-sion in terms of pain, function, and alignment in patients with unilateral adult acquired flatfoot. American Ortho-pedic Foot and Ankle Society (AOFAS) hindfoot scale and Numeric Pain Rating Scale (NPRS) were assessed as outcomes at the baseline (T0), at 6 months (T1), and at 1 year (T2) from surgery. We analyzed data of 20 patients (7 male and 13 female), mean aged 46.6 ? 5.34 years, showed significant differences after 6 months in terms of AOFAS total score (44.30 ? 7.39 vs 96.50 ? 4.89; p = .0001), AOFAS subitems (p < .001), and pain (NPRS: 7.95 ? 1.36 vs 1.05 ? 1.05; p = .0001). At 1 year after surgery (T2), all outcome measures still significantly differ from baseline (p < 01). Therefore, percutaneous MDCO through a minimal skin incision seemed to be safe and effective in the middle and long term in reducing pain and improving function and alignment in patients with unilateral adult acquired flatfoot. ? 2020 by the American College of Foot and Ankle Surgeons.
