Summary

Preservation of JL should be a major consideration when undertaking RTKA. Of note, increasing PFCO to balance the flexion gap while maintaining joint line should be well assessed intra-operatively.

Abstract

Objectives
The aim of this systematic review was to evaluate the evidence on reservation of posterior Femoral condylar offset (PFCO) and Joint line (JL) with improved functional results after Revision Total Knee Arthroplasty (RTKA).

Methods

A comprehensive search of PubMed, Medline, Cochrane, CINAHL, and Embase databases was conducted since the inception of the database to October 2020. All relevant articles were retrieved, and their bibliographies were hand searched for further references on Posterior condylar offset and revision total knee arthroplasty. The search strategy yielded 28 articles. After duplicate removal titles, abstracts and full text were reviewed. Nine studies were assessed for eligibility, four studies were excluded because they did not fully comply with the inclusion criteria. Sex articles were finally included in this systematic review.

Results

Based on this systematic review restoration of the JL and PFCO in RTKR is associated with significant improvement in the post operative range of motion, KSS, OKS, patellar function, and SF-36.

Conclusion

Preservation of JL should be a major consideration when undertaking RTKA. Of note, increasing PFCO to balance the flexion gap while maintaining joint line should be well assessed intra-operatively.
