Robotic technology in total knee arthroplasty: a systematic review

[摘要] Total knee arthroplasty (TKA) is an established and highly effective treatment for patients with symptomatic endstage knee osteoarthritis.1,2 The procedure is performed in over 90,000 patients per year in the United Kingdom.3 Pooled registry data has shown that implant survivorship, assessed with revision as the primary endpoint, is approximately 82% at 25 years follow-up.4,5 However, patient satisfaction and functional outcomes remain inferior to those for total hip arthroplasty.3 Despite advances in implant design, implant material, enhanced recovery programmes, thromboembolic prophylaxis, antibiotic prophylaxis, patient-specific implants, and computer navigation, recent studies have shown that up to 20% of patients remain dissatisfied following TKA.2,6–11 Accurate implant positioning, balanced flexion-extension gaps, proper ligament tensioning, and preservation of the periarticular soft tissue envelope are important surgeon-controlled variables that affect functional outcomes, implant stability, and long-term implant survivorship.12–19 Conceptually, technology that enables these technical objectives to be delivered with greater accuracy and reproducibility may help to further improve outcomes in TKA.
