“…Postoperative arc of flexion ranging from 74°to 103°(mean, 87.1°) has been reported after TKA in stiff knees in series ranging from 11 to 84 knees (Table 4). Our results were comparable to those of previous studies [1,3,18,19,24,27] (Table 4). Although we found knee motion after TKA disappointing in our patients, in all instances, overall motion improved.…”

“…Some authors have reported lack of consistent adequate motion in patients with stiff knees [18,24]. One study suggests ROM of the knee after TKA in these patients may be indistinguishable from that achieved by a comparable group of patients with flexible knees [21].…”

“…In that series, one of 90 knees (1%) was revised because of aseptic loosening of the femoral component. In another clinical series [24], 67 of 84 knees (80%) had no radiolucencies, but 17 had radiolucencies of 1 mm or less at the bone-cement interface of the tibial component at a minimum of 4 years and mean of 9 years. In that series, no knee had aseptic loosening (clinically and radiographically) at the final followup.…”

Does TKA Improve Functional Outcome and Range of Motion in Patients with Stiff Knees?

The main goals of TKA are pain relief and improvement of function and range of motion (ROM). To ascertain whether TKA in patients with stiff knees would relieve pain and improve functional outcome and ROM, we asked four questions: whether (1) Knee Society and WO-MAC scores would improve after TKA; (2) poor preoperative ROM would improve after TKA; (3) the revision rate of TKA in stiff knees would be high; and (4) complication rates would be high in these patients after TKA. We retrospectively reviewed 74 patients (86 knees) with stiff knees (mean age, 56.8 years) who underwent TKAs with a condylar constrained or a posterior stabilized prosthesis. The minimum followup was 5 years (mean, 9.1 years; range, 5-12 years). The mean preoperative Hospital for Special Surgery knee score and Knee Society knee and functional scores were 42, 11, and 42 points, respectively, and postoperatively they were 84, 90, and 84 points, respectively. Preoperative and postoperative total WOMAC scores were 73 and 34 points, respectively. One knee (1.2%) had aseptic loosening of the tibial component and 12 knees (14%) had complications. Despite a relatively high rate of complications, most patients had substantial improvement in function.
