There is a longstanding presumed association between obesity, complications, and revision surgery in primary knee arthroplasty. This has more recently been called into question, particularly in centres where a high volume of arthroplasty is performed. We investigated the correlation between Body Mass Index (BMI), mortality, and revision surgery. This was a cohort study of at least 10 years following primary knee arthroplasty from a single high volume arthroplasty unit. Mortality and revision rates were collected from all patients who underwent primary knee arthroplasty between 2009 and 2010. Kaplan Meier analysis was performed. There were 1161 female and 948 male patients with a mean age of 69 (21 to 97). All cause survivorship excluding mortality was 97.2% up to 13yrs with a minimum of 10 years. The revision rate in this series was 2.8% with no significant difference in revision rates after 10 year between patients with BMI above and below 40 (p=0.438). There was no significant difference in 10–year mortality between patients above and below a BMI of 40 (p=0.238). This study shows no significant difference in the long term survival of total knee replacement between patients with normal and high BMI. Careful consideration should be given before rationing surgery based on BMI alone.
Anatomical reduction of articular fragments in tibial plateau fractures often leads to a void and there is a need to fill dead space and support the articular fragment. MIIG X3 is marketed as high strength injectable graft, which resorbs and remodels fast. Efficacy and complications related to the use of this bone graft substitute were evaluated in this study Between January 2012 and December 2016 we injected calcium sulphate (MIIGX3) in 50 out of 126 consecutive complete articular (AO type C3) tibial plateau fractures that were stabilised with Ilizarov ring fixator. Postoperative CT scans after weight bearing and sequential radiographs were evaluated for union, graft resorption and subsidence. IOWA functional outcome score and complications were recorded.Introduction
Methods
Our unit has extensive experience with the use of Ilizarov circular frames for acute fracture and nonunion surgery. We have observed and analysed fracture healing patterns which question the role of relative stability in fracture healing and we offer limb mechanical axis restoration as a more important determinant. To assess for the presence of external callus, when only relative stability has been achieved but with anatomical restoration of the mechanical axis (ARMA).Introduction
Aim
Circular frames are used to treat a wide spectrum of acute injuries and deformities. We report on our experience of treating both acute and chronic trimalleolar fracture dislocations with a closed technique, utilizing fine wires and a circular frame. Data was collected from all patients treated for either acute or chronic trimalleolar fracture dislocations at a single centre between January 2016 and December 2017. A total of 10 patients were identified, 8 with acute injuries and 2 with chronic/delayed injuries. Clinical and radiological outcomes were recorded, as well as patient reported outcome measures (PROMs) using the Chertsey Outcome Score for Trauma (COST score).Aim
