Progress of lateral unicompartmental knee arthroplasty for lateral compartment osteoarthritis of the knee / 国际外科学杂志

ABSTRACT

With the development of the knee-preservation concept and surgical techniques, lateral unicompartmental knee arthroplasty (UKA) has become an effective method for the lateral compartment osteoarthritis of the knee.The incidence of knee osteoarthritis is low in the lateral compartment, which is different from the medial compartment in anatomical and kinematic characteristics. These two factors increase the challenge of lateral UKA, so the clinical efficacy of lateral UKA has been controversial. With the improvement and renewal of treatment concepts, surgical techniques and prosthesis design, the clinical effect of lateral UKA and the survival rate of the prosthesis have been continuously optimized. This article aims to summarize the characteristics of lateral compartment knee osteoarthritis, clinical efficacy, prosthesis selection, reasons for revision, future application and prospects, combined with relevant literature in recent years, to review the current progress of lateral UKA.
