“…Improvement in ROM is commonly reported by authors but with variable results [2, 6, 11, 13, 19, 20, 22, 23, 26]. Chiang et al [6] observed a mean post‐operative ROM of 79.8° with a 16.6° gain compared to Thomason et al [41] who report a ROM inferior to 45° in 7 cases out of 23, with a flexion contracture over 10° in 10 cases.…”
