Introduction: Metallosis following prosthetic hip and knee replacement is a well-known complication. However, unicompartmental knee arthroplasty (UKA) metallosis is rare. In this paper, we report a case of septic metallosis after unicompartmental knee replacement and we review the literature for the available treatment options.
Case Report: A 83-year-old female patient presented with left periprosthetic knee infection on the top of unicompartmental knee prosthesis three months after septic endocarditis that was treated with anti-biotherapy. Surgical exploration showed severe infected metallosis due to chronic polyethylene wear reaction; hence, management consisted of total synovectomy and debridement of all metallic debris and two stage revision.
Conclusion: Metallosis is a well-known complication after prosthetic hip and knee replacements. However, in UKA, it remains a rare complication where only few cases were reported in the literature.

Background: Spacer-type tibial osteotomy have been proven a novel and effective osteotomy to treat osteoarthritis, while lack of comparison with other surgical methods in younger patients. This study aims to evaluate the short-term clinical outcomes of spacer-type tibial osteotomy versus open wedge high tibial osteotomy (OWHTO) and unicompartmental knee arthroplasty (UKA) for Kellgren-Lawrence (K-L) grade 3-4 osteoarthritis (OA) in patients younger than 65 years.
Methods: This retrospective study analyzed a total of 224 patients with K-L grade 3-4 knee OA treated from March 2018 to November 2020.

Purpose: The purpose of this investigation is to assess and contrast the effectiveness of the two EuroQol five dimensions questionnaire (EQ-5D) versions-EQ-5D-3L and EQ-5D-5L-in assessing one-year quality of life outcomes for patients with knee osteoarthritis (KOA) undergoing unicompartmental knee arthroplasty (UKA).
Material And Method: From the medical records at the Honghui Hospital, Xi'an Jiaotong University, 402 individuals aged 50 and above, who were one-year post-operation, were selected to fill out survey questionnaires during their return hospital visits. Of these, 231 respondents (57.
Varus/valgus angle of the femoral component relative to the tibial component increases risk of bearing dislocation in medial mobile bearing unicompartmental knee arthroplasty.
BMC Musculoskelet Disord

Senior Department of Orthopedics, The Fourth Medical Center of PLA General Hospital, No. 51 Fucheng Road, Beijing, 100048, People's Republic of China.
Background: In medial mobile-bearing unicompartmental knee arthroplasty (MB-UKA), the position of the bearing does not correspond to the planned position which will increasing the risk of bearing dislocation. This study aimed to explore the relationship between the malposition of the femoral and tibial components and the phenomenon of bearing deviation using postoperative radiological measurements.
Methods: One hundred twenty patients who underwent mobile-bearing uni-compartmental knee arthroplasty (MB-UKA) at our hospital between January and August 2023 were enrolled in this retrospective study.

Introduction: Knee osteoarthritis (OA) significantly impacts the quality of life of those afflicted, with many patients eventually requiring surgical intervention. While Total Knee Arthroplasty (TKA) is common, it may not be suitable for younger patients with unicompartmental OA, who might benefit more from High Tibial Osteotomy (HTO). Effective patient education is crucial for informed decision-making, yet most online health information has been found to be too complex for the average patient to understand.
