Augmentation of meniscus repairs with fibrin clot may enhance the healing capacity. Pulling the clot into the tear with a suture ensures that it stays in position. This paper aims to assess the outcome of this technique. 52 patients over 4 years undergoing suture repair of a meniscus tear with blood clot augmentation were collected from a prospective database. Follow up included outcome scores and a questionnaire. Failure was defined as pain or further surgery secondary to meniscal pathology.Abstract

Post-arthroscopic glenohumeral chondrolysis (PAGCL) is a rare, but significant, complication of arthroscopic shoulder surgery that may lead to arthroplasty. Exact causal factors and pathways associated with the development of PAGCL are unknown however a number of patient factors and surgical factors have been implicated. Suture is one of these potential causal factors and currently little is known about the body's immune response to commonly used orthopaedic sutures. The aim of this project is to examine the biological response to 3 commonly used orthopaedic sutures (Ethibond, Fibrewire, and Orthocord) in a murine airpouch model. It was hypothesised that different sutures would elicit a different histological response and that suture wear-debris would induce an increased inflammatory reaction compared to intact suture. Total of 50 male Wister rats (12 weeks old) were used in this study. 5 rats were used per time point per group. Rat air-pouch was created according to a protocol previously described by Sedgewick et al. (1983). Once the pouch was established, on day 6, an incision was made and one of the test materials (intact Ethibond, intact Orthocord, intact Fibrewire, Fibrewire wear-debris) administered. Following wound closure, 5 ml of sterile PBS was injected to suspend the implanted materials. Negative control animals were injected with PBS alone. Rats were sacrificed at 1 and 4 weeks following surgery. The entire pouch was harvested and processed for H&E histology. The images of histological stained sections were digitally photographed and evaluated for presence of synovium and inflammatory reaction. Foreign body giant cells were quantified by two independent, blinded observers.Introduction

The life expectancy of patients with Down syndrome has increased significantly in recent years. Hip abnormalities occur in children with this syndrome but little is known about their natural history in later life. In 65 adults with Down syndrome we found hip abnormalities in 28%, and this was statistically correlated with walking ability. A subgroup of 18 patients was followed by serial examination; this showed that hip instability occurred in adulthood and became worse with time. In some patients, hip instability started after skeletal maturity.
