Diathermy and bone sawing are high aerosol yield procedures.

Aims: Orthopaedic surgery uses many varied instruments with high-speed, high-impact, thermal energy and sometimes heavy instruments, all of which potentially result in aerosolization of contaminated blood, tissue, and bone, raising concerns for clinicians' health. This study quantifies the aerosol exposure by measuring the number and size distribution of the particles reaching the lead surgeon during key orthopaedic operations.

Methods: The aerosol yield from 17 orthopaedic open surgeries (on the knee, hip, and shoulder) was recorded at the position of the lead surgeon using an Aerodynamic Particle Sizer (APS; 0.

Single-stage repair of displaced bucket-handle meniscal tears with anterior cruciate ligament reconstruction leads to good meniscal survivorship : a retrospective cohort study.

Aims: The best surgical strategy for the management of displaced bucket-handle (BH) meniscal tears in an anterior cruciate ligament (ACL)-deficient knee is unclear. Combining meniscal repair with ACL reconstruction (ACLR) is thought to improve meniscal healing rates; however, patients with displaced BH meniscal tears may lack extension. This leads some to advocate staged surgery to avoid postoperative stiffness and loss of range of motion (ROM) following ACLR.

The number of patients "worse than death" while waiting for a hip or knee arthroplasty has nearly doubled during the COVID-19 pandemic.

Aims: The aim of this study was to assess the quality of life of patients on the waiting list for a total hip (THA) or knee arthroplasty (KA) during the COVID-19 pandemic. Secondary aims were to assess whether length of time on the waiting list influenced quality of life and rate of deferral of surgery.

Methods: During the study period (August and September 2020) 843 patients (THA n = 394, KA n = 449) from ten centres in the UK reported their EuroQol five dimension (EQ-5D) scores and completed a waiting list questionnaire (2020 group).

Fixed bearing, all-polyethylene tibia, lateral unicompartmental arthroplasty - A final outcome study with up to 28 year follow-up of a single implant.

Background: Lateral unicompartmental arthroplasty (UKA) constitutes only 5-10% of all unicompartmental replacements performed. Whilst the short and medium term benefits are well documented, there remains concern regarding the higher revision rate when compared with total knee replacement. We report the long term clinical outcome and survivorship of a large series of lateral UKA.

St Georg Sled medial unicompartmental arthroplasty: survivorship analysis and function at 20 years follow up.

Purpose: The peri-operative and short-term benefits of unicompartmental knee arthroplasty (UKA) are well supported in the literature. However, there remains concern regarding the higher revision rate when compared with total knee replacement. This manuscript reports the functional outcome and survivorship of a large series of fixed bearing, medial unicompartmental replacements (St Georg Sled), with a minimum of 20 years follow-up.

Management of the exposed total knee prosthesis, a six-year review.

Introduction: An exposed knee prosthesis is a limb threatening condition. Our unit manages such cases according to a multidisciplinary orthoplastic protocol. Whilst early prosthetic joint infection with dehiscence may be managed by Debridement, Antibiotics and Implant Retention (DAIR) and soft tissue coverage, the majority of these cases are chronic and in our unit are managed by Debridement, Explantation, Antibiotics (spacer and systemic) and Flap (DEAF).

Patient Reported Kneeling Ability in Fixed and Mobile Bearing Knee Arthroplasty.

Kneeling is an important function of the knee joint required for many daily activities. Bearing type is thought to influence functional outcome following UKA and TKA. Self-reported kneeling ability was recorded in 471 UKA and 206 TKA patients with fixed or mobile bearing implants.

Fixed bearing lateral unicompartmental knee arthroplasty--short to midterm survivorship and knee scores for 101 prostheses.

Background: Isolated unicompartmental knee arthritis is less common laterally than medially. Lateral unicompartmental knee arthroplasty (UKA) constitutes only 1% of all knee arthroplasty performed. Use of medial UKA is supported by several published series showing good long-term survivorship and patient satisfaction, in large patient cohorts.

Does anterior cruciate ligament reconstruction lead to degenerative disease?: Thirteen-year results after bone-patellar tendon-bone autograft.

Background: Reporting of long-term outcome of anterior cruciate ligament (ACL) reconstruction with the patellar tendon (bone-patellar tendon-bone [BTB]) autograft is limited. There are concerns that degenerative joint disease is common in the long term, which may be associated with the procedure itself.

Hypotheses: (1) ACL reconstruction with BTB provides good long-term outcome.

Deprivation and outcome of total knee replacement.

Deprivation correlates with poor health and psychosocial variables can affect the symptoms of knee arthritis. Our aim was to determine the effect of deprivation on the level of knee function and health-related quality of life at the time of arthroplasty and 12 months after total knee replacement. From our database of over 2500 knee replacements, we analysed both clinical and quality of life outcome measures.

A reliable DEXA measurement technique for metal-on-metal hip resurfacing.

Introduction: Dual energy X-ray absorptiometry (DEXA) has been used to measure bone mineral density (BMD) around total hip prostheses. With the recent increase in the use of metal-on-metal hip resurfacing, such as the Birmingham hip resurfacing (BHR), we aimed to produce a reliable method of measuring bone density around a metal-on-metal hip resurfacing.

Methods: We performed DEXA scans on 5 patients (7 BHRs), who had undergone resurfacing with the BHR within the past 2 years.

Spontaneous rupture of the popliteus tendon in a 74-year-old woman and review of the literature.

Spontaneous rupture of the popliteus tendon has not previously been reported. We report the case of a 74-year-old patient, discuss its diagnosis and management, and review the current literature on isolated popliteus lesions. A multi-database electronic literature review suggests that the injury is invariably traumatic and has essentially been reported only in young, active individuals.

Septic arthritis of the elbow after chickenpox.

Musculoskeletal complications following chickenpox are rare among immunologically normal children. Septic arthritis after varicella is caused by group A Streptococcus and affects the knee most frequently. We present a case of septic arthritis of the elbow caused by Staphylococcus aureus.
