Objective To evaluate whether preoperative range of motion is a key determinant of postoperative range of motion in A sian patients undergoing conventional total knee arthroplasty. Methods A retrospective review of 302 patients who underwent primary total knee arthroplasty performed by a single surgeon was conducted. Patients who had a fixed flexion deformity of ≥15° were excluded. Postoperative range of motion (ROM) was measured prospectively. Patients were stratified into two groups: preoperative ROM < 110° and preoperative ROM ≥ 110°. Postoperative ROM and mean change in ROM at 6 months and 2 years of follow‐up were then compared using Student's t‐ test. Results Group of ROM < 110° had a poorer postoperative range of motion at both 6‐months and 2‐years of follow‐up than Group of ROM ≥ 110° ( P < 0.001). Postoperatively, Group of ROM < 110° had gained range of motion whereas Group of ROM ≥ 110° had lost range of motion ( P < 0.001). Conclusions Similar to the Western population, preoperative range of motion is a key determinant of postoperative range of motion in Asian patients. This should be taken into consideration by surgeons during preoperative planning and in managing patients’ expectations.
