BACKGROUND: Arthroscopic knee surgery frequently precedes total knee arthroplasty (TKA). There have been mixed data on the effect of prior arthroscopic surgery on results of TKA. The purpose of this study was to compare the 10-year Knee Society Score (KSS), survivorship, and complications of TKA in a cohort of patients who had a previous knee arthroscopy to a control cohort. METHODS: A retrospective review of 1315 TKAs who underwent a primary TKA between 2003 and 2004 was performed...

INTRODUCTION: There are few specific reports of late medial instability after total knee arthroplasty (TKA). We described two cases of late medial instability of the knee due to hip disease with osteoarthritis or rheumatoid arthritis after TKA, which required revision TKA. PRESENTATION OF CASES: An 82-year-old woman experienced right femoral neck fracture due to a fall that required conservative treatment at age 77 years and underwent left TKA at age 80 years. A 68-year-old woman underwent left TKA at age 54 years, right TKA at age 64 years, and left THA at age 67 years...

INTRODUCTION Selective non-operative management (SNOM) of abdominal stab wounds is well established in South Africa. SNOM reduces the morbidity associated with negative laparotomies while being safe. Despite steady advances in technology (including laparoscopy, computed tomography [CT] and point-of-care sonography), our approach has remained clinically driven. Assessments of financial implications are limited in the literature. The aim of this study was to review isolated penetrating abdominal trauma and analyse associated incurred expenses...

BACKGROUND: Patient-reported outcomes are increasingly used as complementary measures to clinical outcomes in total knee arthroplasty (TKA). However, their prognostic importance has yet to be established. We aimed to determine whether the long-term revision risk in TKA relates to pain and Knee Society Score (KSS) measures at baseline, 1, and 2 years. METHODS: This was a registry-based study of primary TKA procedures at a large tertiary care institution between 1995 and 2010...

Skin damage induced by UVR is an escalating problem in dermatology, and increasing incidence of skin cancer, especially for non-melanoma skin cancer, has been reported worldwide. UVR from sun exposure and the production of reactive oxygen species (ROS) is known to be a pivotal factor in the aetiology of skin cancer. The pineal hormone melatonin is recognized as the most potent endogenous antioxidant. Melatonin conducts its antioxidant effects acting directly as a radical scavenger and indirectly by up regulation of antioxidant enzymes...
