Outcomes Following Repeat Collagenase Treatment of Dupuytren Contracture.

Purpose: Injectable collagenase Clostridium histolyticum has been an effective and well-tolerated nonsurgical treatment option for the management of Dupuytren contracture of the hand. The purpose of this study was to determine the efficacy of collagenase injection and adverse event rate in patients who had undergone previous collagenase treatment.

Methods: A retrospective chart review was performed on 332 patients treated with collagenase injection for Dupuytren contracture by three fellowship-trained hand surgeons at a single institution from 2009 to 2019.

Impact of State Opioid Regulation on Postoperative Opioid Prescribing Patterns for Total Knee Arthroplasty: A Retrospective Analysis.

Background: Limited studies have assessed the impact of state regulations on opioid prescribing patterns for patients undergoing total knee arthroplasty (TKA). This study evaluates how Florida House Bill 21 (FL-HB21) affected postoperative opioid prescribing for patients after TKA.

Methods: Institutional review board approval was obtained to retrospectively review all patients who underwent TKA during 3 months of 2017 (pre-law) and 2018 (post-law) by five arthroplasty surgeons in Florida.

Is it Safe to Continue Clopidogrel in Elective Hip and Knee Arthroplasty?

Background: No evidence-based guidelines exist for the perioperative use of clopidogrel in elective hip and knee arthroplasty patients. This study compares the preoperative, intraoperative, and postoperative outcomes of total hip and knee arthroplasty in patients maintained on clopidogrel and with patients whose clopidogrel was held before surgery.

Methods: We retrospectively identified 158 patients taking clopidogrel before undergoing elective total hip or knee arthroplasty.

Complex Total Hip Arthroplasty in a Patient with Klippel-Trénaunay Syndrome: A Case Report.

Case: Klippel-Trénaunay syndrome (KTS) carries manifestations including skeletal dysplasia and prominent vascular malformations. This report details a case of hip dysplasia in the setting of KTS treated with total hip arthroplasty (THA) requiring preoperative embolization, intraoperative angiography for placement of an iliac artery occlusive balloon, and modular hip arthroplasty components for femoral and acetabular dysplasia. Perioperatively, the patient rehabilitated well and was walking painlessly and unassisted at 3 and 12 months postoperatively.

Comparison of Cruciate-Sacrificing vs Posterior-Stabilized Total Knee Replacement Using a Contemporary Total Knee System.

Background: The use of highly conforming polyethylene tibial inserts in cruciate-retaining total knee arthroplasty (TKA) often requires posterior cruciate ligament (PCL) release/sacrifice for balancing (CS TKA). The CS TKA relies on the posterior capsule, collateral ligaments, and articular conformity without a cam or post to achieve stability. Using prospectively collected data we compared clinical outcomes of CS TKA to posterior-stabilized (PS) TKA utilizing a contemporary TKA system.
