The aim of this study was to determine the factors which were responsible for differences between patients achieving the Trust target of discharge on post-operative day 5 after a primary total knee replacement and those not achieving it, in the cohort of over 75 year olds. Of all the patients undergoing a TKR at Addenbrooke's Hospital in 2008, those over 75 were identified (n=103). From the literature pre-, intra- and post-operative factors that had previously been shown to affect length of stay were identified. Patient notes were examined for details on each of these and the patients divided into 2 groups according to whether their discharge was achieved by day 5 or not. Data from 74 operations was available at the time of submission of this abstract. Pearson's Chi-squared test, student's independent t-test or the Mann-Whitney U test were performed on the data depending on the nature of the variable analysed. The following factors were found to be significantly different between the 2 groups at the 95% confidence level: pre-operative use of a walking aid (p=0.033), pre-operative Hb (p=0.003), post-operative Hb (p=0.001), post-operative requirement of a blood transfusion, post-operative complication (p<0.001), post-operative day on which active knee flexion to 90° was achieved (p=0.003). In addition the following factors were found to be significant at the 90% confidence level: age (p=0.082), comorbidity (p=0.086), marital status (p=0.095) and mobilisation by post-operative day 2 (p=0.082)Aim
Methods and Results
The aim of this study was to study the course of the infra-patellar branch of the saphenous nerve (IPBSN) and describe its anatomical variations and relations. Twenty-eight formalin-fixed cadaver lower extremity specimens were methodically dissected in the University Department of Anatomy. Dissection included identifying the saphenous nerve and tracing it distally till it pierced the deep fascia between the tendons of gracilis and sartorius. At this point, the saphenous nerve gave a branch that pierced the sartorius and became subcutaneous, known as the infrapatellar branch. The association of the nerve trunk with the sartorius muscle in terms of whether it originated above it, below it or pierced through it was studied. Following this the nerve was dissected along its course distally to the point of its termination where it gave one to three branches. The relationship of the point of termination of the IPBSN with bony surface landmarks like the medial border of the patella, the apex of the patella and the tibial tuberosity were also studied. The distance of the trunk from medial margin of patella was measured.Aim
