Abstract Background: Pigmented villonodular synovitis (PVNS) is a rare synovial disease with benign hyperplasia, which has been successfully treated with total knee arthroplasty (TKA). The purpose of this study was to investigate the middle-term follow-up outcomes of cruciate-retaining (CR) TKA in patients with PVNS.Methods: From January 2012 to December 2014, a retrospective study was conducted in 17 patients with PVNS who underwent CR TKA as PVNS group. During this period, we also selected 68 patients with osteoarthritis who underwent CR TKA (control group) for comparison. The two groups matched in a 1:4 ratio based on age, sex, body mass index and follow-up time. The range of motion, Knee Society Score, revision rate, disease recurrence, wound complications and the survivorship curve of Kaplan-Meier implant were assessed between the two groups.Results: All patients were followed up at least five years. There were no difference in range of motion, and Knee Society Score between the two groups before surgery and at last follow-up after surgery (p > 0.05). In the PVNS group, no patients with the recurrence of PVNS were found at the last follow-up, one patient underwent revision surgery due to periprosthetic fracture, and three patients had stiffness one year after surgery (17.6% vs 1.5%, p = 0.005; ROM:16°- 81°), but no revision was needed. At seven years, the implant survivorship was 90.0% in the PVNS group and 96.6% in the control group (p = 0.54).Conclusions: This study demonstrated that the function of patients with PVNS who underwent CR TKA had been significantly improved, and the survival rate of implants in these patients were similar to the patients with OA. Consequently, the patients with PVNS who underwent CR TKA might be an achievable option. However, these patients should pay more attention to the occurrence of postoperative stiffness complication.

Abstract Background: Pigmented villonodular synovitis (PVNS) is a rare synovial disease with benign hyperplasia, which has been successfully treated with total knee arthroplasty (TKA). The purpose of this study was to investigate the middle-term follow-up results of cruciate-retaining (CR) total knee arthroplasty (TKA) in PVNS patients.Methods: 17 patients with PVNS were treated with CR TKA between 2012 and 2014. 68 patients with osteoarthritis (OA) who received CR TKA as control group. The two groups matched in a 4:1 ratio based on age,gender, body mass index (BMI) and follow-up time. In the two groups, the range of motion (ROM), Knee Society Score (KSS), revision rate, disease recurrence, complications and the survivorship curve of Kaplan-Meier implant were compared. Results: All patients were followed up at least 7 years. At the last follow-up, no patients with recurrence of PVNS were found. There was no difference in KSS between the two groups, and no patients experienced infection and death. In the PVNS group, 3 patients had stiffness complications but did not need revision. 1 patient underwent revision surgery due to periprosthetic fracture. At 7 years,the implant survivorship was 90.0% in the PVNS group and 96.6% in the control group (p = 0.54).Conclusions: This study demonstrates that the function of PVNS patients who received CR TKA has been significantly improved. The survival rate of implants in PVNS patients is similar to that of OA patients. Consequently, PVNS patients who treated with CR TKA may be an achievable option. However, patients with PVNS should pay more attention to the occurrence of postoperative stiffness complications.

Abstract Background To determine the functional outcomes, complications and revision rates following total knee arthroplasty (TKA) in patients with pigmented villonodular synovitis (PVNS). Materials and methods We conducted a systematic review of the literature. Five studies with a total of 552 TKAs were included for analysis. The methodological quality of the articles was evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale. Functional outcomes, complications and revision rates were assessed. The mean age was 61 years (range 33–94 years) and the mean follow-up period was 61.1 months (range 0.2–35 years). Results All the studies reported improvement in knee function following TKA. Post-operative stiffness was the most frequently reported complication, affecting 32.7% (n = 32) of patients in our review. Symptomatic recurrence of PVNS, component loosening, tibial-component fracture, instability and periprosthetic infection were the main factors leading to the need for revision TKA. Conclusion The findings of this review support the use of TKA to alleviate the functional limitations and pain due to knee degeneration in patients with PVNS. The operating surgeon should be aware of the increased risk of post-operative stiffness, as well as a potentially higher risk of infection. Implant survival should also be considered inferior to the one expected for the general population undergoing TKA.
