“…The significantly lower survival rate for the all polyethylene type was probably due to the higher tibial strain at the adjacent bone compared to the metal-backed implants [6] . There have been controversies regarding the actual mechanism of higher revision rate in all polyethylene tibia but the most common modes are aseptic loosening, progression of osteoarthritis and unexplained pain [3] . In this study, the progression of osteoarthritis precipitated by history of trauma renders the patient to be wheel chaired-bound and decided to do revision surgery.…”

“…However, there have been inconsistent results regarding the long term survivorship of all polyethylene tibia Uni-compartment Knee Arthroplasty (UKA). Several studies reported an acceptable long-term survival and patient outcomes for a medial fixed all polyethylene tibial bearing UKA [3] , [4] , [5] . Bruce et al reported a survival of 85% at 10 years for patient less than 70 years, and 92.4% for patients older than 70 years [3] .…”

Resumen Objetivo Describir el resultado funcional informado por el paciente de una cohorte de pacientes sometidos a artroplastia unicompartimental de rodilla (AUR) en un hospital universitario chileno. Métodos Se diseñó un estudio de cohorte histórica. Se incluyeron todos los pacientes que se sometieron a AUR de platillo fijo entre 2003 y 2019. Un evaluador independiente se puso en contacto con los pacientes en junio de 2020. Se utilizó el índice de artritis de las universidades de Western Ontario y McMaster (WOMAC) para comparar los procedimientos de AUR (medial o lateral), la edad (mayor o menor de 70 años), y el seguimiento (más o menos de 5 años). Resultados Se incluyeron 78 pacientes, en un total de 94 AURs. La mediana de edad fue de 64 años (rango: 43 a 85 años). Hubo 72 (76,6%) casos de AUR medial. Un paciente necesitó revisión para artroplastia total de rodilla (ATR). Un total de 60 pacientes (76,9%), correspondientes a 72 AURs (76,7%), fueron contactados con éxito por teléfono para el seguimiento final. La mediana del puntaje en los dominios del WOMAC fue: dolor – 1 (rango: 0 a 12); rigidez – 0 (rango: 0 a 4); y función física – 2 (rango: 0 a 29). La mediana del puntaje total en el WOMAC fue de 4 (rango: 0 a 44). Los pacientes sometidos a AUR lateral lograron mejores puntuaciones funcionales (p = 0,0432), y el puntaje total en el WOMAC fue similar en pacientes mayores o menores de 70 años (p = 0,3706). Conclusiones La AUR es un tratamiento eficaz y reproducible para pacientes con artrosis de rodilla unicompartimental. La edad parece no afectar los resultados funcionales, y la AUR es un tratamiento eficaz en pacientes mayores de 70 años. Estos resultados deberían animar a los cirujanos de rodilla a aprender esta técnica y a los responsables de las políticas de salud pública a considerar la AUR para la osteoartritis de rodilla.

“…Although MB implants demonstrated faster surgical duration and greater range of motion, their superiority over FB implants still remains unclear [ 12 , 13 , 14 , 15 ]. Previous systematic reviews and meta-analyses, which compared the two implants, were not exhaustive, finding no clinically relevant differences in patient-reported outcome measures (PROMs), ROM, and rate of complication [ 8 , 9 , 16 , 17 , 18 , 19 , 20 , 21 ]. However, several clinical studies have been recently published, which have not yet been considered in any previous meta-analysis, and an update of the current evidence is required [ 22 , 23 , 24 , 25 , 26 ].…”

Introduction: Whether mobile-bearing (MB) unicompartmental knee arthroplasty (UKA) performs better than fixed-bearing (FB) implants in patients with monocompartmental osteoarthritis (OA) still remains unclear. Therefore, a meta-analysis comparing MB versus FB for UKA was conducted to investigate the possible advantages of MB versus FB in patient-reported outcome measures (PROMs), range of motion (ROM), and complications. We hypothesised that the MB design performs better than FB. Methods: This systematic review was conducted according to the 2020 PRISMA guidelines. In December 2021, PubMed, Web of Science, Google Scholar, and Embase were accessed, with no time constraints. All the clinical investigations comparing MB versus FB bearing for UKA were accessed. Only studies published in peer-reviewed journals were considered. Studies reporting data on revision settings were excluded, as were those combining unicompartmental and total knee arthroplasty. Results: Data from 25 studies (4696 patients) were collected; 58% (2724 of 4696 patients) were women. The mean length of follow-up was 45.8 ± 43.2. The mean age of the patients was 65.0 ± 5.6 years. No difference was found in range of motion (p = 0.05), Knee Scoring System (p = 0.9), function subscale (p = 0.2), and Oxford Knee Score (p = 0.4). No difference was found in the rate of revision (p = 0.2), aseptic loosening (p = 0.9), deep infections (p = 0.99), fractures (p = 0.6), and further extension of OA to the contralateral joint compartment (p = 0.2). Conclusion: The present meta-analysis failed to identify the possible superiority of the MB implants over the FB for UKA in patients with monocompartmental knee osteoarthritis. Long observational investigations are required to evaluate possible long-term complications and implant survivorship. These results should be interpreted within the limitations of the present study.
