Association Between Preoperative Radiological Findings and Outcomes After Total Knee Arthroplasty.

Introduction Total knee arthroplasty (TKA) is a widely accepted surgical intervention for patients with advanced knee osteoarthritis, aimed at reducing pain and improving functional mobility. Preoperative radiological evaluations, including assessments of joint space narrowing, osteophytes, varus/valgus deformities, and subchondral sclerosis, are essential for planning the surgery and predicting postoperative outcomes. Although extensive research has been conducted internationally, data focusing on populations in Saudi Arabia remain limited.

Complications Post Abdominoplasty After Surgical Versus Non-surgical Massive Weight Loss: a Comparative Study.

Purpose: This study aims to investigate the rate of short- and long-term complications as well as the need for operative revisions after abdominoplasty for patients following surgical versus non-surgical weight loss methods.

Methods: This is a retrospective chart review that enrolled consecutive patients undergoing abdominoplasty across a 5-year period, aged 18 years and above, opting for abdominoplasty after weight loss achieved through bariatric surgery or diet and exercise alone.

Results: A total of 364 patients lost weight through bariatric surgery and 106 by diet and exercise alone.

Teaching and evaluation methods of medical ethics in the Saudi public medical colleges: cross-sectional questionnaire study.

Background: Saudi Arabia is considered one of the most influential Muslim countries being as the host of the two most holy places for Muslims, namely Makkah and Madina. This was reflected in the emphasis on teaching medical ethics in a lecture-based format as a part of the subject of Islamic culture taught to medical students. Over the last few years, both teaching and evaluation of medical ethics have been changing as more Saudi academics received specialized training and qualifications in bioethics from western universities.
