Abstract:

BACKGROUND: Total knee arthroplasty technique and prosthetic design have been improved with the development of clinical practice and experimental research, however, the treatment of patella is a bone of contention in total knee arthroplasty.
OBJECTIVE: To analyze the features of routine patellar resurfacing, routine patellar reservation and selective patellar resurfacing in order to provide preferred plan for patellar treatment in total knee arthroplasty.
METHODS: PubMed, Wanfang and VIP databases were searched by the first author with key words of “total knee arthroplasty, patellar, replacement” both in English and Chinese. Inclusive criteria: ①Papers regarding prosthetic design in total knee arthroplasty. ②Biocompatibility of total knee prosthesis. ③Patellar treatment in total knee arthroplasty. After reading titles and abstract, 32 manuscipts were included in this review.
RESULTS AND CONCLUSION: For a long time, scholars have different opinions on how to treat patella in total knee arthroplasty and form three main opinions, namely, routine patellar resurfacing, routine patellar reservation and selective patellar resurfacing. Currently, how to treat patella in total knee arthroplasty still need further long-term follow-up and randomized controlled studies. Based on retrospective analysis and randomized controlled studies, degree of confidence, time duration, and evaluating criteria should be considered to make reasonable decision to guide clinical application.
