Background There has been a resurgence in anterior cruciate ligament (ACL) repair for proximal tears using modern surgical techniques and technology. This study aims to compare ACL repair with reconstruction using MRI, clinician-measured and patient-reported outcome measures (PROMs). Methods A post-hoc analysis was performed on prospectively collected data from 20 consecutive primary ACL repairs by

Prior tuberosity screw fixation of the osteotomized tubercle can lead to favorable outcomes in retro-tubercular bi-planar opening wedge high tibial osteotomy Knee (IF 1.9) Pub Date : 2023-11-03 Seong Yun Park, Sung Bae Park, Jade Pei Yuik Ho, Nguyen Thanh Tu, Yong Seuk Lee
Background Exact information regarding fixing the tuberosity screw during retro-tubercular opening-wedge high tibial osteotomy (RT-OWHTO) is still lacking. The purpose of this study was to determine whether prior tuberosity screw fixation before plate fixation of main osteotomy fragment can prevent complications associated with tuberosity screw. Methods From 2019 to 2021, patients who underwent RT-OWHTO

An accurate method for measuring knee joint space width despite variations in beam projection angles Knee (IF 1.9) Pub Date : 2023-11-03 Sung Eun Kim, Keehyun Kim, Myung Chul Lee, Hyuk-Soo Han, Byung Sun Choi, Du Hyun Ro
Background Assessing knee osteoarthritis (OA) severity through joint space width (JSW) measurements can be difficult due to anatomical variations, beam projection angle (BPA) errors, and patient posture during X-rays. Although various methods address these issues, a consensus on the reference point for accurate measurement is lacking. Therefore, establishing a precise evaluation method for JSW is imperative

The efficacy of platelet-rich plasma in treating osteoarthritis with an inflammatory phenotype: A 5-year follow up retrospective study Knee (IF 1.9) Pub Date : 2023-11-04 Yang Chen, Song Wu, Zi Wen, Xu Cao, Antonia Rujia Sun, Yong Luo, Hongxing Li
Background We aimed to explore whether platelet-rich plasma (PRP) can delay and reduce the incidence of total knee arthroplasty (TKA) and improve clinical symptoms in patients with inflammatory phenotype knee osteoarthritis (I-KOA). Methods This was a retrospective cohort study with a 5-year follow up. We selected patients with I-KOA based on typical magnetic resonance imaging findings. Patients were

The effect of virtual reality on pain, kinesiophobia and function in total knee arthroplasty patients: A randomized controlled trial Knee (IF 1.9) Pub Date : 2023-11-04 Ozan Gür, Selda Başar
Background Virtual reality (VR) has emerged as a promising new therapeutic approach, showing promise in the treatment of patients with a variety of diseases. This study aimed to investigate the effect of VR on pain, kinesiophobia, and function in patients undergoing total knee arthroplasty (TKA). Methods This randomized controlled trial was performed on patients who had TKA due to osteoarthritis at

12-Year clinical and radiological results of a double-blind randomized controlled trial comparing posterior cruciate-retaining versus posterior-stabilized total knee arthroplasty Knee (IF 1.9) Pub Date : 2023-11-03 R.F.M.R. Kersten, A.J. de Vries, J.J.A.M. van Raaij, R.W. Brouwer
Background A subject of ongoing debate among orthopedic surgeons is the importance of preserving the posterior cruciate ligament in total knee arthroplasty (TKA), but long-term survival studies are scarce. The aim of this study was to compare long-term survival rates, and clinical and radiological follow up of a double-blind randomized controlled trial comparing posterior cruciate-retaining (PCR) versus

Fifteen-year survival analysis of an oxidised zirconium total knee arthroplasty Knee (IF 1.9) Pub Date : 2023-11-03 Joseph TR Fennelly, Stylianos Papalexandris, Jill Pope, Joanne Yorke, John S Davidson, Alasdair JA Santini
Background Early studies have found Oxidised Zirconium (OxZr-Nb) total knee arthroplasties to have a low incidence of failure in young, high demand patients. Theoretically this is because they are low friction and hard wearing. However, there are a paucity of studies reporting on the outcome of these implants beyond ten years. The purpose of our study was to present an in-depth 15-year survival analysis
