Robotic unicompartmental knee arthroplasty: Current challenges and future perspectives

[摘要] Unicompartmental knee arthroplasty (UKA)is an established and highly effective treatment for patients with end-stage diseaseaffecting one compartment of the kneejoint.1 The procedure accounts for between8% and 10% of all knee arthroplasty procedures performed in the United Kingdom andUnited States.2,3 There are several advantagesof performing UKA over total knee arthroplasty (TKA), including reduced operatingtime, decreased intraoperative blood loss,reduced periarticular soft-tissue trauma,improved preservation of bone stock, betterrestoration of native kinematics, increasedpatient satisfaction, and improved functionaloutcomes.4-7 However, UKA is associatedwith decreased implant survivorship andincreased revision rates compared withTKA.8,9 Accuracy of component positioningand limb alignment are important prognostic variables that affect implant survival andtime to revision surgery following UKA.9-11Consequently, techniques that improve theaccuracy of implant positioning and limbalignment in UKA may help to improve longterm survivorship and reduce the burden ofrevision disease.
