Midterm Survivorship of Robotic-Assisted Lateral Unicompartmental Knee Arthroplasty

Survival of lateral unicompartmental knee arthroplasty at short‐, mid‐, and long‐term follow‐up: a systematic review and meta‐analysis

“…Two thousand one hundred and sixty studies were then screened for eligibility based on their titles and abstracts. After a screening and retrieval process, 40 articles received a full‐text evaluation for eligibility and finally, 26 studies 7–9,15–37 were included in this meta‐analysis. Detailed information regarding study selection is displayed in Figure 1.…”

“…Refinements in patient selection criteria, surgical technique as well as instrumentation, and implant design aimed at better accommodating the lateral compartment, have greatly contributed to the increase in implant survivorships during this period. 8,16,19,20,22,28,32,37 It is therefore likely that the exclusion of a study 21 published in 1996 could reduce heterogeneity and improve the 10-year survival in our sensitivity analysis. Surprisingly, we further stratified studies into two subgroups according to the publication year of 2015 and found significantly lower survivorships at longer-term follow-up (15-20 years) among recently published studies.…”

“…Research into lateral UKA has flourished in the last decade as the procedure is becoming more frequent. Refinements in patient selection criteria, surgical technique as well as instrumentation, and implant design aimed at better accommodating the lateral compartment, have greatly contributed to the increase in implant survivorships during this period 8,16,19,20,22,28,32,37 . It is therefore likely that the exclusion of a study 21 published in 1996 could reduce heterogeneity and improve the 10‐year survival in our sensitivity analysis.…”

Fixed-bearing is superior to mobile-bearing in lateral unicompartmental knee replacement: a retrospective matched-pairs analysis

“…Since bearing dislocation is not possible with a FB design, the requirements for ligamentous balancing are not as crucial as for MB‐UKR. In recent years, robotic‐assisted UKR has emerged and has shown improved implant positioning compared with the conventional technique [4] as well as good clinical outcome and survivorship [10, 15]. However, an advantage of robotic‐assisted lateral UKR over conventional technique in terms of survivorship and clinical outcome has not yet been demonstrated [23].…”

Anatomical and Biomechanical Features of the Lateral Compartment of the Knee and Associated Technical Aspects of Unicompartmental Knee Arthroplasty: Lecture

“…Так, ряд авторов, говоря в своих исследованиях об одномыщелковом эндопротезировании коленного сустава, отмечают, что как при медиальной, так и при латеральной частичной артропластике коленного сустава, выполненной с помощью роботизированной системы, отмечаются лучшие результаты по сравнению со стандартной техникой операции (преимущественно касающиеся позиционирования компонентов эндопротеза). Роботизированное одномыщелковое эндопротезирование позволяет добиться выравнивания механической оси нижней конечности, максимально приближенной к нативной, более точного ориентирования компонентов эндопротеза, что, в свою очередь, снижает частоту ревизионных вмешательств после первичной артропластики [37,38,39,40].…”
