What Factors are Associated With Conversion to Knee Arthroplasty After Subchondroplasty?

Background: Subchondral bone marrow lesions identified on knee MRI are believed to play a role in osteoarthritis-associated pain. The subchondroplasty procedure is an arthroscopically assisted procedure for treating such lesions to avoid larger procedures such as knee arthroplasty. However, the survivorship free of conversion to arthroplasty and the factors associated with an increased likelihood of conversion of subchondroplasty to arthroplasty have not been well defined.

Decreased costs with maintained patient satisfaction after total joint arthroplasty in a physician-owned hospital.

Objective: Comparing total joint arthroplasty (TJA) costs and patient-reported outcomes between a physician-owned hospital (POH) and a non-POH.

Methods: Costs for each 90-day TJA episode at both facilities were determined, and patients were asked to complete a patient satisfaction questionnaire.

Results: Average TJA episode cost was $19,039 at the POH, compared to $21,302 at the non-POH, a difference of $2,263 ( = 0.

Accelerometer-based navigation improves early patient-reported outcomes after gap-balanced total knee arthroplasty.

Objective: To investigate the effect of accelerometry-based navigation (ABN) on early clinical outcomes after TKA.

Methods: 71 TKAs were performed via ABN and 37 TKAs via standard instrumentation (STD). Patients were assessed at the second post-operative visit to determine early KOOS, JR scores.

Vascular extravasation of injectable bioresorbable bone cement during aspiration and injection of calcaneal bone cyst.

A 27-year-old woman underwent aspiration and bioresorbable cement injection of a simple bone cyst. During injection, cement was seen on fluoroscopy extravasating into the posterior vein of the ankle. The procedure was immediately stopped, and the patient remained hemodynamically stable.

Triaging Total Hip Arthroplasty During the COVID-19 Pandemic.

Purpose Of Review: The purpose of this review was to evaluate the available literature to determine what may be considered urgent indications for total hip arthroplasty, in the unprecedented setting of the worldwide COVID-19 pandemic.

Recent Findings: SARS-CoV-2 is a novel coronavirus currently presenting in the form of a global pandemic, referred to as COVID-19. In this setting, multiple states have issued executive orders prohibiting "elective" surgery, including arthroplasty, in order to preserve healthcare resources.

Anal Squamous Cell Carcinoma in African Americans with and without HIV: A Comparative Study.

Background: The incidence of anal carcinoma has increased over the last few decades especially in African Americans (AA) despite the use of highly active anti-retroviral therapy (HAART). Here, we retrospectively review oncologic outcomes of AA patients with anal squamous cell carcinoma (SCC) with and without HIV to further examine the cause of this trend.

Materials And Methods: All adult AA patients diagnosed with anal SCC from 2000 to 2007 who met inclusion were examined.
