Research Development Of Minimally Invasive Surgery For Unicompartmental Knee Arthroplasty

Objective: The article is aimed at summarizing the superiority and indications of UKA(unicompartmental knee arthroplasty)and the evolution of MIS-UKA(minimally invasive surgery of unicompartmental knee arthroplasty),and discussing the clinical outcomes in order to provide the theoretical guidance.Methods: The related papers were searched from CNKI,Wanfang database,Pub Med,Springer Link database system with the keywords “knee;unicompartmental knee arthroplasty;minimally invasive surgery;robot assisted navigation system”.To analysis and summarize these papers for the newest research and clinical advance.Results: Within the recent years,UKA has achieved satisfactory results.With the advance of the single condyle prosthesis and the surgical technique,MIS-UKA come into clinical practice.Especially with the application of the operation navigation system and the robot assisted system on UKA,the accurate implantation of unicompartmental prosthesis come true.The mobil platform and the fixed platform prosthesis have their own advantages and the similar revision rate.The postoperative clinical results mainly depend on the appropriate cases and the surgical techniques.Conclusion: With the improvement of the prosthesis design and the surgical technique,the superiority of MIS-UKA is becoming more and more prominent.In addition,the indications of UKA are also expanded.The computer and robot assisted navigation system can improve the accuracy of the prosthesis implantation and restore the alignment of the lower limb accurately,which still needs more long-term follow-up to confirm.There are both advantages and disadvantages in the fixed platform and the mobile platform,and the choice depends on the specific conmditions of every patient.
