chondrotoxicity in vitro. Methods. Chondrocytes were harvested from bovine femoral condyle cartilage
and isolated using collagenase-containing media. At 24 hours after
seeding 15 000 cells per well onto a 96-well plate, chondrocytes
were treated with media (DMEM/F12 + ITS), PBS, 1:1 lidocaine (2%):PBS,
1:1 bupivacaine (0.5%):PBS, 1:1 lidocaine (2%):HA, 1:1 bupivacaine (0.
5%):HA, or 1:1 HA:PBS for one hour. Following treatment, groups
had conditions removed and 24-hour incubation. Cell viability was
assessed using PrestoBlue and confirmed visually using fluorescence
microscopy. Results. Media-treated groups had a mean of 1.55×10. 4. cells/well
(. sem. 783). All treated cells showed statistically significant reduced
viability when compared with media alone (all p <

survived significantly more than bupivacaine (2.44×10. 3. cells/well
(. sem . 830)) (p <
0.001). Lidocaine + HA (1.45×10. 3. cells/well
(. sem. 596)) was not significantly more cytotoxic than lidocaine
(2.24×10. 3. cells/well (. sem. 341)) (p = 0.999).
There was no statistical difference between the chondrotoxicities

Lower-extremity orthopaedic procedures may be performed under either regional or general anaesthesia, or a combination of both techniques. There is a growing body of evidence supporting the benefits of regional anaesthesia, with meta-analyses of randomised controlled trials and registry data suggesting decreases in deep surgical site infections, thromboembolic events, cardiopulmonary complications and length of stay associated with use of regional anaesthesia. In patients undergoing foot and ankle surgery specifically, there is evidence demonstrating decreased post-operative pain, nausea, vomiting, opioid use and unplanned hospital admission. This supports an increased role for the use in regional anaesthesia in patients undergoing foot and ankle surgery. However, the type of

Intra-articular injections of steroid into the hip are used for a variety of reasons in current orthopaedic practice. Recently their safety prior to ipsilateral total hip replacement has been called into question owing to concerns about deep joint infection.

Carpal tunnel syndrome is the commonest nerve entrapment syndrome. There is still controversy over the method of anaesthesia for this procedure.

Polymethylmethacetate (PMMA) is a bone cement used in over 725,000 primary hip arthroplasties in 2018. Cement integrity is affected by external factors, including temperature, mixing technique and moisture uptake, which can influence cement microstructure. Changes in the cement microstructure may ultimately threaten the survivorship of the implant. The introduction of enhanced recovery and various local

time, the problems associated with allogenic blood transfusion have led
to interest in alternative methods for managing blood loss after
total knee replacement, including the use of auto-transfusion of
fluid from the patient’s surgical drain. It is safe to combine peri-articular
infiltration with auto-transfusion from the drain. We performed
a randomised clinical trial to compare the concentration of local anaesthetic
in the blood and in the fluid collected in the knee drain in patients
having either a peri-articular injection or a femoral nerve block.

Introduction. Operating theatre airflow can be measured using pulsed lasers (particle image velocimetry) but the process is difficult to do in 3D. Cup, vane or hot wire anemometers provide only 2D information. 3D measurements enable better understanding of airflow. Patients/Materials & Methods. We used a Windmaster ultrasound 3D anemometer (Skyview systems), which uses three ultrasound transmitters to measure velocity in XYZ planes, with a sampling rate of 32 Hz. Post processing was done using MATLAB. An operating theatre with an Howorth Exflow canopy was studied. Equipment, including lights, was moved. A 50 cm grid was marked, and measurements were made at intervals up to the ceiling. Door opening was observed within the clean zone and the peripheral zone, next to the door and on the opposite side of the room.

1. There seem to be two distinct methods of destruction of the foot, once pain sensibility has been lost: the first is a slow erosion and shortening associated with perforating ulcers under the distal weight-bearing end of the foot. The second is a proximal disintegration of the tarsus in which mechanical forces often determine onset and progress of the condition. 2. Once the tarsus begins to disintegrate it is difficult to halt the rapid destruction of the foot. 3. It is possible to detect early stages of this condition in time to take preventive measures.

Anterior cruciate ligament reconstruction has been traditionally performed as an inpatient due to post-operative analgesic requirements. Increased patient demands and pressures of bed shortages have led to the development of day case surgery.

Urinary catheterization in the postoperative period is known to increase the risk of deep joint infection following arthroplasty.

Aims. As the world continues to fight successive waves of COVID-19 variants, we have seen worldwide infections surpass 100 million. London, UK, has been severely affected throughout the pandemic, and the resulting impact on the NHS has been profound. The aim of this study is to evaluate the impact of COVID-19 on theatre productivity across London’s four major trauma centres (MTCs), and to assess how the changes to normal protocols and working patterns impacted trauma theatre efficiency. Methods. This was a collaborative study across London’s MTCs. A two-month period was selected from 5 March to 5 May 2020. The same two-month period in 2019 was used to provide baseline data for comparison. Demographic information was collected, as well as surgical speciality, procedure, time to surgery, type of anaesthesia, and various time points throughout the patient journey to theatre. Results. In total, 1,243 theatre visits were analyzed as part of the study. Of these, 834 patients presented in 2019 and 409 in 2020. Fewer open reduction and internal fixations were performed in 2020 (33.5% vs 38.2%), and there was an increase in the number of orthoplastic cases in 2020 (8.3% vs 2.2%), both statistically significant results (p < 0.000). There was a statistically significant increase in median time from 2019 to 2020, between sending for a patient and their arrival to the
