“…Moreover, they showed that postoperative flexion contractures improve with conservative management during the first three years. Other investigators have demonstrated similar flexion contracture improvement with rehabilitation and physiotherapy after intraoperative correction [4,7,24]. The second aim of this study was to compare the evolution over time of this newly developed flexion contracture with those patients who did not develop a contracture postoperatively.…”

“…The incidence of fixed flexion deformity after TKA ranges from 1.4 to 17 % [ [1][2][3][4][5][6]16]. While some studies have reported that the condition does not improve postoperatively [17][18][19][20], other investigators have shown gradual recovery with conservative management [19,[21][22][23][24].…”

“…It has been well established that the presence of a preoperative flexion contracture increases the risk of developing a postoperative flexion contracture [5]. However, the incidence and natural history of a newly developed flexion contracture in patients after total knee arthroplasty has not been extensively studied [4,21].…”

“…While the majority of flexion contractures detected immediately after TKA may be attributed to the presence of pain and joint effusion [4,34,36], less information is available on newly developed flexion contractures noted at sixweeks. Aderinto et al observed that the presence of a preoperative fixed flexion deformity was a good predictor for the development of post-operative fixed flexion deformity [21].…”

“…Flexion contracture is an unwanted complication of total knee arthroplasty (TKA), occurring in 1.4 to 17 % of patients [1][2][3][4][5][6]. Patients with a postoperative flexion contracture have an increased prevalence of anterior knee pain, probably secondary to an abnormal distribution of forces across the prosthetic components with an increased load in the posterior aspect of the tibial plateau and the patellofemoral joint [7].…”

Purpose We investigated the incidence, natural history, and functional consequences of a newly developed flexion contracture after total knee arthroplasty (TKA). Methods Forty patients with full knee extension preoperatively who developed a postoperative flexion contracture were match-paired 1:2 with 80 patients who had full extension. The incidence of a newly developed flexion contracture, ROM, and Knee Society scores (KSS) at six weeks, four months, and one year were analysed. Results The incidence of a new flexion contracture at sixweeks was 14 %, but diminished to 5 % and 0.3 % at fourmonths and one year, respectively. One year after surgery, there was no difference in the KSS (p=0.5). Conclusions This study showed that the majority of patients who developed a new flexion contracture after TKA have full knee extension one year postoperatively. Moreover, knee extension and KSS at one year are equivalent to those patients who did not developed a flexion contracture.
