Purpose: Controversy exists on the best fixation for total knee arthroplasty (TKA). Non-cemented fixation has been theorized to improve patient outcomes and longevity of implantation but no study has focused on comparison between cemented or cementless posterior-stabilized implants despite being the most commonly or second most frequently utilized implant in most total knee replacement registries.
Methods: Inclusion criteria with observational and interventional papers, and review articles that focused on patients with cementless and cemented PS TKAs were used to analyze outcomes such as implant survivorship, complication, or revision rates.
Purpose: Meniscal allografts and biodegradable meniscal implants are attractive surgical options for painful subtotal or total meniscectomies. In order to get the best results, these should be as similar as possible to the original meniscus in terms of shape, structure, and volume. Three-dimensional meniscus sizing could be an approach to improve the accuracy of meniscus matching.

Materials And Methods: With the hypothesis that arthroplasties may have less complications without increasing mortality even for Garden I and Garden II fractures, we retrospectively reviewed 317 hips with femoral neck fractures operated between January 2015 and August 2019. The mean age at time of surgical intervention was 82.
We report a rare case of symptomatic adverse local tissue reaction in a patient with a ceramic-on-ceramic total hip bearing surface and review the literature. Probably, ceramic wear debris is not entirely inert and may lead to adverse local tissue reactions.

As the symptomatic treatment of this disaster complication is poor and has low efficacy, a preventive treatment would be beneficial. Vitamin C has been reported to be efficient in preventing CRPS in elective scheduled surgery.

Design: Methodological study.
Setting: A 20-bed orthopedic unit and 20-bed geriatric unit.
Purpose: The long incubation period and asymptomatic spread of COVID-19 present considerable challenges for health care institutions when patients return to elective surgery.
Methods: A retrospective review of the first adult elective cases performed between May 18, 2020 and June 14, 2020, after the end of lockdown was analysed in Belgium to answer the following questions: (1) for the 236 cancelled patients during the outbreak, how easy was rescheduling? (2) How useful was universal RT-PCR testing and chest CT scan for the 211 orthopaedic and trauma admissions? (3) How were surgical difficulty category, number of operations and complications different when compared to the pre-COVID period? (4) How would patients balance the benefit of surgery against the unknown risk of developing COVID-19?
Results: Before surgery, blood tests for anaesthesiology and imaging related to the surgical procedure were scheduled prior to universal testing (COVID-19 PCR and chest CT) performed 72-120 hours before surgery. Among the 211 asymptomatic patients who were tested before surgery, six had positive PCR, while no abnormality was found on the chest CT scan of all the patients.
Introduction: Human spontaneous osteonecrosis of the knee (SPONK) is still challenging as the current treatments do not allow the production of hyaline cartilage tissue. The aim of the present study was to explore the therapeutic potential of cartilage regeneration using a new biphasic scaffold (type I collagen/hydroxyapatite) previously loaded or not with concentrated bone marrow cells.
Material And Methods: Female rabbits were operated of one knee to create articular lesions of the trochlea (three holes of 4 × 4mm).
Purpose: Lateralized tibial tubercle is a cause of patellar instability. Before proceeding with reduction of the tibial tubercle-trochlear groove (TT-TG) distance, surgeons prefer to know whether this distance is pathologic. However, the pathological value remains discussed and may vary with the size of the knee.
