What Role Does Patello-Femoral Joint Degeneration Have on Pain and Function After Unicompartmental Knee Arthroplasty? A Prospective Observational Cohort Study.

Background: Influences on anterior knee pain, stair climbing limitations, and function such as rising from sitting are poorly understood in unicompartmental knee arthroplasty (UKA). Original indications for UKA excluded patients who had patello-femoral disease, while more recent studies have expanded the indications to include these patients. This study examined the influence of the patello-femoral joint degeneration on patient-reported outcome measures relating to anterior knee pain and function after UKA.

Incidence of Anterior Knee Pain and Functional Difficulty in a Prospectively Recruited Cohort Following Total Knee Arthroplasty With Selective Patellar Resurfacing.

Background: The influence of patellar resurfacing on anterior knee pain, stair climbing, and functional activity outcomes following total knee arthroplasty (TKA) are incompletely understood. This study examined the influence of patellar resurfacing on patient-reported outcome measures (PROMs) relating to anterior knee pain and function.

Methods: The Knee Injury and Osteoarthritis Outcome Score of Joint Replacement (KOOS, JR.

Outpatient-Focused Joint Arthroplasty Is the Future: The Midwest Center for Joint Replacement Experience.

Background: Perhaps, the most significant developments in joint arthroplasty in the past decade have been in the area of multimodal perioperative management reducing pain, nausea, and length of stay leading to outpatient arthroplasty.

Methods: Over a 2-year period, we performed 1230 arthroplasty cases including partial knee, total hip, total knee, and selected revision cases.

Results: Patient satisfaction ranged from 98% to 100% great/good.

Anxiety and Depression Associated With Burden in Caregivers of Patients With Brain Metastases.

Purpose/objectives: To describe and examine the relationship between caregiver burden and the affective disorders anxiety and depression in caregivers of patients with brain metastases.

Design: Cross-sectional, descriptive, correlational.

Cobalt to Chromium Ratio is Not a Key Marker for Adverse Local Tissue Reaction (ALTR) in Metal on Metal Hips.

The diagnosis of adverse local tissue reaction (ALTR) after metal-on-metal total hip arthroplasty (MoMTHA) presents a significant challenge. No single biomarker is specific for ALTR. The purpose of this study was to determine if the ratio of cobalt to chromium ions is useful for diagnosing ALTR in MoMTHA.
