Pigmented villonodular synovitis (PVNS) has a high but variable recurrence rate. Prior studies do not compare recurrence-free survival (RFS) for various surgical approaches or salvage surgery for relapse. We therefore determined: (1) RFS after excision; (2) RFS after salvage surgery for relapse; (3) factors associated with relapse. We retrospectively reviewed the medical records of 49 patients with previously untreated PVNS of the knee (12 localized, 37 diffuse) who were treated with synovectomy from 1991 to 2008; there were 22 males and 27 females, with mean age of 35.2 years (range, 10-73). Minimum followup was 1 year (mean, 6.2 years; range, 1-13). Twenty-one patients had a relapse. The RFS for index surgery was 75% and 53%; and for salvage surgery was 71% and 52% at 2 and 5 years respectively. The RFS was 95% for open versus 62% for arthroscopic synovectomy at 2 years, 71% and 41% at 5 years. The RFS was 91% for localized and 70% for diffuse PVNS at 2 years, 73% and 48% at 5 years. Diffuse disease (RR = 4.49) and arthroscopic synovectomy (RR = 3.30) were associated with relapse. Recurrence was frequent after synovectomy. Reexcision can salvage relapses as successfully as excision for primary disease; however, morbidity was associated with additional surgeries.

A wide variation exists in rehabilitation after total hip arthroplasty (THA) in part due to a paucity of evidence-based literature. We asked whether a minimally invasive surgical approach, a multimodal approach to pain control with revised anesthesia protocols, hip restrictions, or preoperative physiotherapy achieved a faster rehabilitation and improved immediate short-term outcome. We conducted a systematic review of 16 level I and II studies after a strategy-based search of English literature on OVID Medline, PubMed, CINAHL, Cochrane, and EMBASE databases. We defined the endpoint of assessment as independent ambulation and ability to perform activities of daily living. Literature supports the use of a multimodal pain control to improve patient compliance in accelerated rehabilitation. Multimodal pain control with revised anesthesia protocols and accelerated rehabilitation speeds recovery after minimally invasive THA compared to the standard approach THA, but a smaller incision length or minimally invasive approach does not demonstrably improve the short-term outcome. Available studies justify no hip restrictions following an anterolateral approach but none have examined the question for a posterior approach. Preoperative physiotherapy may facilitate faster postoperative functional recovery but multicenter and welldesigned prospective randomized studies with outcome measures are necessary to confirm its efficacy.
