Abstract:

Objective

To evaluate the effect of gap balance (GB) and measured resection (MR) in total knee arthroplasty (TKA).

Methods

Searches for randomized controlled clinical trials on the comparison of GB and MR effects during TKA published from May 2009 to May 2021 were performed in PubMed, Embase, CNKI, Vip, Wanfang, China Biomedical Literature Database, etc. And the magazine catalogue and references were searched manually. Cochrane risk of bias tool was used to assess the underling risk of bias of the included literature, and the quality of included literature was assessed with Jadad score. Meta analysis was performed in postoperative knee society function score (KSFS), postoperative knee society score (KSS), postoperative range of motion, postoperative angle between lower limb force line and leg anatomical axis, postoperative mechanical axis angle, postoperative joint space, intraoperative osteotomy and operation time using Review Manager 5.3.

Results

A total of 16 articles were included for meta analysis, including 12 in foreign languages and 4 in Chinese. MR was better in the overall KSFS and KSS than GB (MD=2.12, 95%CI: 0.74~3.50, P < 0.01), while GB was better in the angle between the lower limb force line and the leg anatomical axis (MD=-1.00, 95%CI: -1.86~0.13, P < 0.05), and the angle between the mechanical axis than MR (MD=-0.39, 95%CI: -0.65~-0.13, P < 0.01).

Conclusion

In the treatment of moderate and severe knee osteoarthritis with TKA, MR has a better functional score, while GB has more advantages in imaging results.
