Abstract

Abstract:

Objective

To evaluate the effect of infrapatellar fat pad in knee functional recovery following total knee replacement.

Methods

All randomized controlled trials (RCTs) and retrospective Cohort Studies (RCSs) comparing the effect of infrapatellar fat pad in knee functional recovery in primary TKA were searched from Cochrane Library, Embase, PubMed, CBM, VIP, Wang Fang date and CNKI. At the same time conference papers were identified manually. A quality assessment of the included literatures was evaluated by Cochrane system evaluation manually. Revman 5.3 was used for the Meta-analysis.

Results

Eight literatures involving 1,474 TKA were identified including 696 cases underwent infrapatellar fat excised and 778 cases preserved infrapatellar fat. The two groups were comparable regarding length of patellar tendon (MD=-2.34, 95% CI: -3.38-1.31, P<0.05), WOMAC scores (MD=2.34, 95% CI: 2.04-2.65, P<0.05), AKS (MD=-0.77, 95% CI: -1.02-0.52, P<0.05), Insall-Salvati (MD=-0.04, 95%CI: -0.09-0.01, P>0.05), postoperative pain (MD=12.58, 95% CI: 3.24-48.75, P<0.05), knee flexion (MD=-7.53, 95% CI: -20.27-5.21, P>0.05), wound revision (MD=0.01, 95% CI: -0.01-0.02, P>0.05).

Conclusions

Compared to in frapatellar fat excised group, the preserved group had lesser degree of patellar tendon spasm, higher knee function lower and can reduce anterior pain of the knee.
