Is it safe to perform elective orthopaedic surgery with high community rates of COVID-19? An observational cohort study.

Introduction: During the first wave of the COVID-19 pandemic, University Hospitals Birmingham NHS Foundation trust was able to recommence elective orthopaedic surgery using private hospitals procured by the NHS as COVID-19 free 'green' sites. We report on the safety of elective orthopaedic surgery with high rates of community transmission.

Methods: We conducted an observational cohort study on consecutive NHS patients attending three private hospitals between 4 May 2020 and 16 June 2020.

Patellofemoral joint replacement - Mean five year follow-up.

Background: The Femoro Patella Vialli FPV is a second-generation patellofemoral arthroplasty implant. It is the second most commonly used patellofemoral implant in the National Joint Registry of England and Wales. This is the first published mid-term outcome series for this prosthesis.

Mechanical Symptoms of Osteoarthritis in the Knee and Arthroscopy.

The potential benefit of arthroscopy as a treatment for knee osteoarthritis is contentious, with National Institute for Health and Care Excellence stating that, "There is uncertainty regarding the efficacy of the procedure." This is a study of a consecutive series of patients with osteoarthritis of the knee, suffering from mechanical symptoms, such as giving way, catching, and locking, and undergoing arthroscopic debridement, including chondroplasty and meniscectomy where appropriate. A total of 33 patients were reviewed at a mean period of 24 months (standard deviation 3 months) and follow-up data were obtained for 28 of these patients.

Knee Osteochondritis Dissecans Treated by the AO Hook Fixation System: A Four Year Follow-Up of an Alternative Technique.

Surgical fixation is recommended for stable osteochondritis dissecans (OCD) lesions that have failed nonoperative management and for all unstable lesions. In this study we set out to describe and evaluate an alternative method of surgical fixation for such lesions. Five knees with unstable OCD lesions in four male adolescent patients with open physes were treated with the AO Hook Fixation System.

Dysfunction of the posterior cruciate ligament in total knee arthroplasty.

Purpose: Total knee arthroplasty (TKA) is typically carried out either with retention (CR) of the posterior cruciate ligament (PCL) or with sacrifice of this ligament and implantation of a posterior stabilised (PS) prosthesis. This paper investigates a comparison of PCL function in knees treated for osteoarthritis with TKA where the PCL is preserved to those knees treated with TKA and posterior stabilisation.

Methods: One hundred and sixty-eight patients (232 knees) who had undergone TKA with either a PS or CR implant were included in the study.
