To identify unanswered questions about the prevention, diagnosis, treatment, and rehabilitation and delivery of care of first-time soft-tissue knee injuries (ligament injuries, patella dislocations, meniscal injuries, and articular cartilage) in children (aged 12 years and older) and adults. The James Lind Alliance (JLA) methodology for Priority Setting Partnerships was followed. An initial survey invited patients and healthcare professionals from the UK to submit any uncertainties regarding soft-tissue knee injury prevention, diagnosis, treatment, and rehabilitation and delivery of care. Over 1,000 questions were received. From these, 74 questions (identifying common concerns) were formulated and checked against the best available evidence. An interim survey was then conducted and 27 questions were taken forward to the final workshop, held in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritization. This was conducted by healthcare professionals, patients, and carers.Aims
Methods
The knee is the most commonly injured joint in sporting accidents, leading to substantial disability, time off work and morbidity (1). Treatment and assessment vary around the UK (2), whilst there remains a limited number of high-quality randomised controlled trials assessing first time, acute soft tissue knee injuries (3,4). As the clinical and financial burden rises (5), vital answers are required to improve prevention, diagnosis, treatment, rehabilitation, and delivery of care. In association with the James Lind Alliance, this BASK, BOSTAA and BOA supported prioritising exercise was undertaken over a year. The James Lind Alliance methodology was followed; a modified nominal group technique was used in the final workshop. An initial survey invited patients and healthcare professionals to submit their uncertainties regarding soft tissue knee injury prevention, diagnosis, treatment, rehabilitation, and delivery of care. Seventy-four questions were formulated to encompass common concerns. These were checked against best available evidence. Following the interim survey, 27 questions were taken forward to the final workshop in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritisation by groups of healthcare professionals, patients, and carers.Introduction
Methods
Knee braces are limited to providing passive support. There is currently no brace available providing both continuous monitoring and active robot-assisted movements of the knee joint. This project aimed to develop a wearable intelligent motorised robotic knee brace to support and monitor rehabilitation for a range of knee conditions including post-surgical rehabilitation. This brace can be used at home providing ambulatory continuous passive movement obviating the need for hospital admissions. A wearable sensing system monitoring knee range of motion was developed to provide remote feedback to clinicians and real-time guidance for patients. A prototype of an exoskeleton providing dynamic motion assistance was developed to help patients complete their exercise goals and strengthen their muscles. The accuracy and reliability of those functions were validated in human participants during exercises including knee flexion/extension (FE) in bed and in chair, sit-to-stand and stand-to-sit.Abstract

Introduction
Methodology
A spotlight has been placed upon virtual assessment of patients during the coronavirus pandemic. This has been particularly prevalent in the assessment of acute knee injuries. In this study we aim to assess the accuracy of telephone triage, confirmed by Magnetic Resonance Imaging (MRI) in the diagnosis of acute knee injuries. Case records of patients triaged by telephone in the acute knee clinic at Leeds General Infirmary were analysed. Provisional diagnoses made following telephone triage were compared to radiological diagnoses made on subsequent MRI scans. Diagnostic accuracy was compared between those patients assessed virtually and those assessed in face-to-face clinics.Abstract

To determine the effectiveness of LIA compared to ACB in providing pain relief and reducing opiates usage in hamstring graft ACL reconstructions. In a consecutive series of hamstring graft ACL reconstructions, patients received three different regional and/or anaesthetic techniques for pain relief. Three groups were studied: group 1: general anaesthetic (GA)+ ACB (n=38); group 2: GA + ACB + LIA (n=31) and group 3: GA+LIA (n=36). ACB was given under ultrasound guidance. LIA involved infiltration at skin incision site, capsule, periosteum and in the hamstring harvest tunnel. Analgesic medications were similar between the three groups as per standard multimodal analgesia (MMA). Patients were similar in demographics distribution and surgical technique. The postoperative pain and total morphine requirements were evaluated and recorded. The postoperative pain was assessed using the visual analogue scores (VAS) at 0hrs, 2hrs, 4hrs, weight bearing (WB) and discharge (DC).Abstract

Fractures of the articular surface of the patella or the lateral femoral condyle usually occur following acute dislocation of the patella. This study looked at the radiological and functional outcomes of fixation of osteochondral fractures Twenty-nine patients (18 male, 11 female) sustained osteochondral fractures of the knee following patellar dislocation. All patients had detailed radiographic imaging and MRI scan of the knee preoperatively. An arthroscopic assessment was done, followed by fixation using bio-absorbable pins or headless screws either arthroscopically or mini-open arthrotomy. VMO plication or MPFL repair were done if necessary. MRI scan was done at follow-up to assess for healing of the fixed fragment prior to patient discharge.Abstract
Introduction
Methods
Fracture dislocation of the knee involves disruption of knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre. Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee (IKDC) score and Knee Injury & Osteoarthritis Outcome Score (KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements and complications.Abstract

Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Eighty-seven patients with knee dislocation were treated at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 4 weeks was preferred unless the patient was too unstable (Injury severity score>16). The collaterals were repaired and augmented using a variety of autografts, allografts or synthetic grafts. PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score.Abstract

The aim of this study was to evaluate the effect of a single per operative injection of sodium hyaluronate (HA, Viscoseal¯) into the knee following arthroscopy. This was a prospective, randomised controlled study. Knee arthroscopy patients were randomised into two groups: one receiving bupivicaine and the other sodium hyaluronate. Pre and post operative VAS scores for pain and Western Ontario and MacMaster Universities (WOMAC) scores for knee function were obtained. Forty eight patients of a single surgeon were randomised into two groups of 24. Both groups were similar as regards to age, sex, etc. Three patients withdrew from the study after randomisation. There was significant drop in pain scores for the Viscoseal¯ group compared to Bupivicaine group particularly between three-six weeks period (p< 0.05) and a significant improvement in WOMAC scores in the study group compared to control at 3 and 6 weeks (p=0.01). Viscosupplementation after arthroscopic knee surgery offers significantly improved function and pain relief over the medium term period (three-six weeks).
The aim of this study was to determine current practice in anterior cruciate ligament reconstruction amongst BASK members. This was an internet-based survey where members were invited to complete a questionnaire on ACL reconstruction. Of the 365 BASK surgeons performing ACL reconstruction, 241 completed the questionnaire (response rate 66%). 147(61%) of surgeons used both hamstring and patellar tendon grafts, 71(29%) used only hamstrings and 21(9%) used patellar tendon only. All surgeons used ipsilateral autograft. 157 (65%) used the transtibial technique for femoral tunnel placement with 80(33%) using the anteromedial portal technique. Of those using the anteromedial portal, the most common femoral fixation devices were the Endobutton (34%) and RCI screw (34%). Interference screw fixation (81%) was the most common tibial fixation in the same group of surgeons with the RCI screw being the most common (63%). 19% (45/241) of surgeons were performing double bundle ACL reconstructions in select cases. Hamstring femoral fixation was with a suspension device in 79% and interference screw in 18%. Of those using a suspension device the Endobutton was most common (48%) followed by Transfix (26%) and Rigidfix (19%). Tibial fixation was most commonly achieved by interference screw (57%) followed by Intrafix (30%). With patellar tendon graft the most popular femoral fixation was with an interference screw (66%) followed by suspension (34%). All surgeons used interference screw for tibial fixation. 90% of surgeons (217) allow immediate full weight-bearing as tolerated irrespective of fixation type with 8% delaying full weight bearing between 1 and 3 weeks. The results show the wide spread of variation in practice of ACL reconstruction. With recent renewed interest in a more anatomic placement of tunnels, the use of the anteromedial portal may continue to increase. With such a wide variation in techniques, grafts and fixation implants used, a register may help assess outcomes.
We aim to create a set of reference data of commonly used scoring systems in the normal population, and to compare these results with published postoperative scores for commonly performed knee operations. This was a questionnaire-based study and a total of 744 questionnaires were sent out, of which 494 replies were received. Six scoring systems were addressed: Lysholm and Oxford Knee Scores, Tegner and UCLA activity scales and Visual Analogue Scales (VAS) for both pain and function. Data was collected into groups based on age (20–29, 30–39, 40–49, 50–59, 60–69, 70–79, 80–89 years). The reference data obtained was then compared to published postoperative scores for knee arthroplasty and ACL reconstruction, to assess whether these patients did indeed return to “normal”. The mean scores for sequential age groups (described above) were as follows: Oxford Knee Score – 13, 13, 14, 14, 17, 15, 17; Lysholm Knee Score – 96, 95, 92, 89, 89, 89, 79; Tegener Activity Scale – 6, 5, 5, 4, 4, 3, 3; UCLA Activity Scale – 8, 7, 7, 7, 6, 6, 5; VAS pain – 5, 8, 10, 9, 14, 12, 20; VAS function 96, 95, 90, 90, 86, 84, 84. Symptom based scoring systems (Oxford Knee Score, Lysholm) were independent of age whereas activity scores (Tegner, UCLA) decreased with age. There was no significant difference detected between scores in different sexes in the same age group. Compared to published scores in an age-matched population following TKR, the data obtained showed that patients do not return to normal scores following arthroplasty. Following ACL reconstructive surgery, activity scores were higher than compared to the data obtained from our population. Data generated from this study can be used as reference data and can play an important role in interpreting post-intervention scores following knee surgery.
Paradoxical cerebral embolism is seen in 50–60% of patients following hip and knee arthroplasty surgery. It is responsible for post-operative symptoms like confusion and cerebral ischemic episodes. Embolism is less common with the use of uncemented implants. No study has looked into incidence of cerebral emboli in hip resurfacing. We undertook a prospective randomised study to look at the incidence of cranial emboli in hip resurfacing. Patients were randomized to receive either uncemented or cemented femoral component. An arm of the study included evaluation of the effects of femoral venting by randomising patients to ‘venting’ or ‘no venting’ of proximal femur intra-operatively. The operations were performed by a single surgeon using a uniform surgical technique. Transcranial Doppler device was used to quantify the occurrence and distribution of cerebral microemboli. Emboli counts were recorded continuously and were correlated any major procedural event. Eight patients (5 vented, 3 unvented) underwent cemented resurfacing and 7 patients (4 vented, 3 unvented) had cementless resurfacing. There was no difference between the two groups for age, gender, weight, or ASA status. Peri-operatively both groups were similar for vital observations (heart rate, temperature, blood pressure), haemoglobin change, mini – mental score at day 1 and 2, and oxygen saturation at day 1 and 3. The mean number of significant emboli in the cemented group was 8.1 and in the cementless group was 1.7 (significant, p=0.009). Venting did not influence rate of emboli however, venting was independently associated with significantly higher drainage (mean 604mls compared to 335mls without venting, p=0.018). There was no significant difference in post-operative haemoglobin or number of units transfused. Cranial emboli occur commonly after hip resurfacing. Their incidence is significantly reduced by the use of uncemented femoral component, however venting of proximal femur doesnot appear to make any difference.
Among these cases, 71% were performed by senior trainees. The consultant’s log book data also suggested the similar trends. Statistically, trainee performed with consultant scrubbed versus consultant performed (P = <
0.0001), trainee performed with consultant in theatre versus consultant performed(P = 0.0318) and trainee performed with consultant scrubbed versus trainee performed with consultant in theatre (P = 0.002)
To counter this, training hospitals should be given financial incentives to train in surgery, or procedures performed by trainees should be priced differently to account for the time lost by training.
