Research background

Knee osteoarthritis seriously affects the quality of life of the elderly. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis. Anterior knee pain (AKP) after TKA is the main cause of dissatisfaction in the elderly. The management of AKP after total knee replacement is very important.

Research motivation

Although total knee replacement is very successful, postoperative AKP is common and a major cause of patient dissatisfaction. By studying the influencing factors of AKP after TKA, we can improve the quality of life of patients and improve the surgical methods.

Research objectives

To study the influencing factors of AKP after TKA. We identified certain intraoperative factors that may improve the occurrence of postoperative AKP. It provides some help for the management of AKP after TKA.

Research methods

This study is a meta-analysis. We combined some previous randomized controlled trials to get new conclusions. We analyzed the influence of several different factors on AKP after TKA.

Research results

There are few randomized controlled trials for many factors, and more high-quality studies are needed to further explore.

Research conclusions

We found that patellar replacement or not did not affect the incidence of postoperative AKP. We found that different assessment methods for AKP may produce different results.

Research perspectives

More randomized controlled trials are needed for further validation in the future.
