Anecdotal reports suggest some cementless Oxford Unicompartmental Knee Replacements (OUKRs) have painful early subsidence of the tibial component with valgus rotation and/or posterior tilting. The incidence of subsidence and its association with pain is poorly understood. This radiographic study aimed to evaluate the incidence of tibial subsidence and five-year patient reported outcome measures (PROMs) of a cementless OUKR cohort. Cementless OUKRs from a high-volume centre with acceptable post-operative and five-year radiographs were included. Subsidence was determined by measuring the angle of the tibial tray/tibial axis angle and distance between the tibial tray axis and fibula head on anteroposterior and lateral radiographs using a custom MATLAB program. Analysis of 5-year PROMs assessed the relationship between subsidence and pain. Radiographs indicating tibial subsidence were validated by two observers.Abstract
Introduction
Methodology
This study aims to compare the clinical and functional outcomes and donor site morbidity of anterior cruciate ligament reconstruction with hamstring tendon autograft and peroneus longus tendon autograft in patients with complete anterior cruciate ligament rupture. Patients who underwent ACL reconstruction from February 2018 to July 2019 were randomly allocated into two groups (hamstring and peroneus longus). Functional scores (IKDC and Lysholm scores) and pain intensity by visual analogue score were recorded preoperatively, 3, 6months, 1, and 2 years postoperatively. Donor site morbidities were assessed with thigh circumference measurements in hamstring group and ankle scoring with the American foot and ankle score in peroneus longus group.Abstract

Setting
We undertook a prospective randomised controlled trial to investigate the efficacy of autologous retransfusion drains in reducing the need for allogenic blood requirement after unilateral total knee replacement. We also monitored the incidence of post-operative complications. There were 86 patients in the control group, receiving standard care with a vacuum drain, and 92 who received an autologous drain and were retransfused postoperatively. Following serial haemoglobin measurements at 24, 48 and 72 hours, we found no difference in the need for allogenic blood between the two groups (control group 15.1%, retransfusion group 13% (p = 0.439)). The incidence of post-operative complications, such as wound infection, deep-vein thrombosis and chest infection, was also comparable between the groups. There were no adverse reactions associated with the retransfusion of autologous blood. Based on this study, the cost-effectiveness and continued use of autologous drains in total knee replacement should be questioned.
