Comparison between achilles tendon reinsertion and dorsal closing wedge calcaneal osteotomy for the treatment of insertional achilles tendinopathy: A meta-analysis.

BACKGROUND

The debridement and Achilles tendon reinsertion (DATR) have been the most common surgical approach for the treatment of Insertional Achilles Tendinopathy (IAT), while dorsal closing wedge calcaneal osteotomy (DCWCO) has recently gained popularity as an alternative surgical option. This study aimed to systematically review the published literature on both surgical techniques and compare their clinical outcomes and complication rates.

METHODS

A systematic review was performed according to the PRISMA guidelines using Medline, Embase, and Scopus databases. The inclusion criteria encompassed clinical studies reporting functional outcomes and complications, with a minimum of 10 patients and at least 12 months of follow-up.

RESULTS

Seven studies (n = 169) were included for the analysis of DATR, and eight studies (n = 227) were included for the analysis of open DCWCO. Both groups showed a similar improvement in AOFAS score. The overall complication rates were 16.6% in the DATR group and 9.2% in the DCWCO group, but the difference was not statistically significant. However, there was a significantly higher incidence of wound complications in the DATR group (10.1%, 95% C.I.: 4.7-15.6) compared to the DCWCO group (2.5%, 95% C.I.: 0.6-4.4) as the confidence intervals did not overlap.

CONCLUSIONS

Clinical outcomes and overall complication rates of both techniques were comparable, although DCWCO had a lower incidence of wound complications. Further research should be focused on prospective studies comparing the two techniques to corroborate the current findings.
