“…Although Houdek et al [9] did not compare the incidence of complications to the control group, their most common complication in their study was the loss of knee ROM, which was similar with our study. According to the previous reports, the revision rate of the patients with PVNS was as high as 21%, which was signi cantly higher than the incidence of published primary TKA for OA [9,26]. In our tudy, only one patient underwent revision because of periprosthetic fracture.…”

“…The PVNS most frequently affects the knee, although there were long-term follow-up studies and shortterm complications in the previous literature with the evaluation of PVNS in arthroplasty, there was no clear middle-term follow-up control study. The previous TKA treatment in patients with PVNS was a minor cohort study, primarily to assess implant survival and function, and did not quantify the risk of postoperative complications, which may be due to the fewer patients [9,25]. Although Houdek et al [9] did not compare the incidence of complications to the control group, their most common complication in their study was the loss of knee ROM, which was similar with our study.…”

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.

An unusual case of pigmented villonodular synovitis after total knee arthroplasty presenting with recurrent hemarthrosis

et al. 2018

Pigmented villonodular synovitis (PVNS) is a benign proliferative joint disease, which is a rare finding after total knee arthroplasty (TKA). There is currently no link between PVNS and TKA, and it has been described infrequently in the literature. Its presentation has varied along with the time that it presents postoperatively. We describe a case of a patient who presents with recurrent hemarthrosis 4 years after TKA. The patient had no previous history of PVNS and had an arthroscopy 1 year after the index operation with no evidence of synovitis. We present details of the first case with a review of imaging and pathology and a brief review of the literature on PVNS occurring after TKA.

“…Total knee arthroplasty (TKA) has been successfully used to improve the function and relieve pain in patients with PVNS. According to some articles, the survival rate of prosthesis ranges from 80 to 85% in patients with PVNS who have been followed up for more than 10 years [9]. In addition, the incidence of postoperative complications of TKA also provided acceptable results in a large number of patients diagnosed with PVNS [10].…”
