Objectives. Nylon sutures and skin staples are used commonly in total knee arthroplasty (TKA) surgical wound closure. However, there is no study that compares the wound healing efficacy and patient satisfaction scores of both techniques in the same knee. Methods. We randomised 70 patients who underwent primary TKA into two groups. In one group of 34 patients, the skin at the upper half of the wound was closed with skin staples and the lower half of the wound was closed with simple interrupted nylon sutures. In the other group of 36 patients, the skin at the upper half of the wound was closed with nylon stitches and the lower half of the wound was closed with skin staples. We recorded the wound closure time, pain score at the time of stitch removal, wound complication rate, patient satisfaction score, and the Hollander wound evaluation score at the post-operative periods of five days, 14 days, six weeks, three months, and six months. Each half wound was analysed separately. Results. The mean patient body mass index was 26.8 kg/m. 2. (standard deviation 6.3). A total of 70 nylon stitched wounds and 70 skin stapled wounds were analysed. There were no significant differences in wound complication rates, patient satisfaction score, and the Hollander wound evaluation score between both types of wounds (p > 0.05). The wound closure time for skin stapled wounds was significantly lower than the nylon stitched wounds (p < 0.001). However, the skin stapled wounds had a significantly higher pain score at the time of stitch removal (p < 0.001). Conclusion. Skin staples and nylon stitches had comparable results with respect to wound healing and
The aim of this study was to surveil whether the standard operating procedure created for the NHS Golden Jubilee sufficiently managed COVID-19 risk to allow safe resumption of elective orthopaedic surgery. This was a prospective study of all elective orthopaedic patients within an elective unit running a green pathway at a COVID-19 light site. Rates of preoperative and 30-day postoperative COVID-19 symptoms or infection were examined for a period of 40 weeks. The unit resumed elective orthopaedic services on 29 June 2020 at a reduced capacity for a limited number of day-case procedures with strict patient selection criteria, increasing to full service on 29 August 2020 with no patient selection criteria.Aims

Spinopelvic mobility plays an important role in functional acetabular component position following total hip arthroplasty (THA). The primary aim of this study was to determine if spinopelvic hypermobility persists or resolves following THA. Our second aim was to identify patient demographic or radiological factors associated with hypermobility and resolution of hypermobility after THA. This study investigated patients with preoperative posterior hypermobility, defined as a change in sacral slope (SS) from standing to sitting (ΔSSstand-sit) ≥ 30°. Radiological spinopelvic parameters, including SS, pelvic incidence (PI), lumbar lordosis (LL), PI-LL mismatch, anterior pelvic plane tilt (APPt), and spinopelvic tilt (SPT), were measured on preoperative imaging, and at
six weeks and a minimum of
one year postoperatively. The severity of bilateral hip osteoarthritis (OA) was graded using Kellgren-Lawrence criteria.Aims

Day-case arthroplasty is gaining popularity in Europe. We report outcomes from the first 12 months following implementation of a day-case pathway for unicompartmental knee arthroplasty (UKA) and total hip arthroplasty (THA) in an NHS hospital. A total of 47 total hip arthroplasty (THA) and 24 unicompartmental knee arthroplasty (UKA) patients were selected for the day-case arthroplasty pathway, based on preoperative fitness and agreement to participate. Data were likewise collected for a matched control group (n = 58) who followed the standard pathway three months prior to the implementation of the day-case pathway. We report same-day discharge (SDD) success, reasons for delayed discharge, and patient-reported outcomes. Overall length of stay (LOS) for all lower limb arthroplasty was recorded to determine the wider impact of implementing a day-case pathway.Aims
Methods
Aims. Medial unicompartmental knee arthroplasty (UKA) is associated
with successful outcomes in carefully selected patient cohorts.
We hypothesised that severity and location of patellofemoral cartilage
lesions significantly influences functional outcome after Oxford
medial compartmental knee arthroplasty. Patients and Methods. We reviewed 100 consecutive UKAs at minimum eight-year follow-up
(96 to 132). A single surgeon performed all procedures. Patients
were selected based on clinical and plain radiographic assessment.
All patients had end-stage medial compartment osteoarthritis (OA)
with sparing of the lateral compartment and intact anterior cruciate ligaments.
None of the patients had end-stage patellofemoral OA, but patients
with anterior knee pain or partial thickness chondral loss were
not excluded. There were 57 male and 43 female patients. The mean
age at surgery was 69 years (41 to 82). At surgery the joint was
carefully inspected for patellofemoral chondral loss and this was documented
based on severity of cartilage loss (0 to 4 Outerbridge grading)
and topographic location (medial, lateral, central, and superior
or inferior). Functional scores collected included Oxford Knee Score

Aims. Reconstruction of the acetabulum after failed total hip arthroplasty
(THA) can be a surgical challenge in the presence of severe bone
loss. We report the long-term survival of a porous tantalum revision
acetabular component, its radiological appearance and quality of
life outcomes. Patients and Methods. We reviewed the results of 46 patients who had undergone revision
of a failed acetabular component with a Paprosky II or III bone
defect and reconstruction with a hemispherical, tantalum acetabular
component, supplementary screws and a cemented polyethylene liner. Results. After a minimum follow-up of ten years (ten to 12), the survivorship
of the porous tantalum acetabular component was 96%, with further
revision of the acetabular component as the end point. The ten-year
survivorship, with hip revision for any reason as the end point,
was 92%. We noted excellent pain relief (mean Western Ontario and
McMaster Universities Arthritis Index (WOMAC) score pain 92.6, (40
to 100)) and good functional outcomes (mean WOMAC function 90.3
(30.9 to 100), mean University of California Los Angeles activity
scale 5 (2 to 10)) and generic quality of life measures (mean Short
Form-12 (SF-12) physical component 48.3 (18.1 to 56.8), mean SF-12
mental component 56.7 (32.9 to 70.3)).
We present the outcomes in 38 consecutive patients who had total ankle replacement using the Ankle Evolution System with a minimum follow-up of four years. Pain and function were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) score and regular standardised anteroposterior and lateral weight-bearing radiographs were obtained.
Aims. The aim of this study was to evaluate antegrade autologous bone
grafting with the preservation of articular cartilage in the treatment
of symptomatic osteochondral lesions of the talus with subchondral
cysts. Patients and Methods. The study involved seven men and five women; their mean age was
35.9 years (14 to 70). All lesions included full-thickness articular
cartilage extending through subchondral bone and were associated
with subchondral cysts. Medial lesions were exposed through an oblique
medial malleolar osteotomy, and one lateral lesion was exposed by
expanding an anterolateral arthroscopic portal. After refreshing
the subchondral cyst, it was grafted with autologous cancellous
bone from the distal tibial metaphysis. The fragments of cartilage
were fixed with 5-0 nylon sutures to the surrounding cartilage.
Function was assessed at a mean follow-up of 25.3 months (15 to
50), using the American Orthopaedic Foot and Ankle Society (AOFAS)
ankle-hindfoot outcome score. The radiological outcome was assessed
using MRI and CT scans. Results. The mean AOFAS score improved from 65.7 (47 to 81) preoperatively
to 92 (90 to 100) at final follow-up, with 100%
The purpose of this study was to determine the access to and ability to use telemedicine technology in adult patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA), and to determine associations with the socioeconomic characteristics of the patients, including age, sex, race, and education. We also sought to understand the patients’ perceived benefits, risks, and preferences when dealing with telemedicine. We performed a cross-sectional survey involving patients awaiting primary THA and TKA by one of six surgeons at a single academic institution. Patients were included and called for a telephone-administered survey if their surgery was scheduled to be between 23 March and 2 June 2020, and were aged > 18 years.Aims
Methods
Metal allergy in knee arthroplasty patients is a controversial topic. We aimed to conduct a scoping review to clarify the management of metal allergy in primary and revision total knee arthroplasty (TKA). Studies were identified by searching electronic databases: Cochrane Central Register of Controlled Trials, Ovid MEDLINE, and Embase, from their inception to November 2020, for studies evaluating TKA patients with metal hypersensitivity/allergy. All studies reporting on diagnosing or managing metal hypersensitivity in TKA were included. Data were extracted and summarized based on study design, study population, interventions and outcomes. A practical guide is then formulated based on the available evidence.Aims
Methods
Robotic-assisted total knee arthroplasty (RA-TKA) is theoretically more accurate for component positioning than TKA performed with mechanical instruments (M-TKA). Furthermore, the ability to incorporate soft-tissue laxity data into the plan prior to bone resection should reduce variability between the planned polyethylene thickness and the final implanted polyethylene. The purpose of this study was to compare accuracy to plan for component positioning and precision, as demonstrated by deviation from plan for polyethylene insert thickness in measured-resection RA-TKA versus M-TKA. A total of 220 consecutive primary TKAs between May 2016 and November 2018, performed by a single surgeon, were reviewed. Planned coronal plane component alignment and overall limb alignment were all 0° to the mechanical axis; tibial posterior slope was 2°; and polyethylene thickness was 9 mm. For RA-TKA, individual component position was adjusted to assist gap-balancing but planned coronal plane alignment for the femoral and tibial components and overall limb alignment remained 0 ± 3°; planned tibial posterior slope was 1.5°. Mean deviations from plan for each parameter were compared between groups for positioning and size and outliers were assessed.Aims
Methods
The aim of this study was to identify the origin and development of the threshold for surgical intervention, highlight the consequences of residual displacement, and justify the importance of accurate measurement. A systematic review of three databases was performed to establish the origin and adaptations of the threshold, with papers screened and relevant citations reviewed. This search identified papers investigating functional outcome, including presence of arthritis, following injury. Orthopaedic textbooks were reviewed to ensure no earlier mention of the threshold was present.Aims
Methods
Aims. Hemiarthroplasty of the hip is usually carried out through either
a direct lateral or posterior approach. The aim of this prospective
observational study was to determine any differences in patient-reported
outcomes between the two surgical approaches. . Patients and Methods. From the Swedish Hip Arthroplasty Register we identified patients
of 70 years and above who were recorded as having had a hemiarthroplasty
during 2009. Only patients who had been treated with modern prostheses
were included. A questionnaire was posted to those who remained
alive one year after surgery. A total of 2118 patients (78% of those
available) with a mean age of 85 years (70 to 102) returned the
questionnaire. . Results. Patients who had undergone surgery through a posterior approach
reported a higher health-related quality of life (HRQoL, EQ-5D mean
0.52 versus 0.47, p = 0.009), less pain (visual
analogue scale mean 17 versus 19, p = 0.02) and greater
satisfaction with the result of surgery (visual analogue scale mean
22 versus 24, p = 0.02) than those who had a direct
lateral approach. However, after adjusting for age, gender, cognitive
impairment and American Society of Anesthesiologists grade, no association
was found between surgical approach and HRQoL, residual pain or patient
satisfaction. Take home message: The surgical approach for hemiarthroplasty
does not seem to affect the patient-perceived HRQoL, residual pain
or
Aims. The objective of this double-blind randomised controlled trial
was to assess whether ultrasound guidance improved the efficacy
of corticosteroid injections for Morton’s neuroma (MN). . Patients and Methods. In all, 50 feet (40 patients) were recruited for this study but
five feet were excluded due to the patients declining further participation.
The mean age of the remaining 36 patients (45 feet) was 57.8 years
(standard deviation (. sd. ) 12.9) with a female preponderance
(33F:12M). All patients were followed-up for 12 months. Treatment
was randomised to an ultrasound guided (Group A) or non-ultrasound
guided (Group B) injection of 40 mg triamcinolone acetonide and
2 ml 1% lignocaine, following ultrasound confirmation of the diagnosis. . Results. The mean visual analogue score for pain improved significantly
in both groups (Group A – from 64 mm, . sd. 25 mm to 29 mm, . sd. 27;
Group B – from 69 mm, . sd. 23 mm to 37 mm, . sd. 25)
with no statistical difference between them at all time-points.
The failure rate within 12 months of treatment was 11/23 (48%) and
12/22 (55%) in Groups A and B, respectively (p = 0.458). The improvement
