Abstract

Achilles tendon ruptures are a common injury afflicting predominantly the young male occasional sportsman. Previous studies have shown that outcome is better with surgical repair for the young active patient. There is no consensus as to whether there is a difference in outcome between open and percutaneous minimally invasive surgery (MIS). A meta-analysis was undertaken to compare the clinical outcomes of MIS with conventional open surgical repair. Six randomised controlled trials of 277 Achilles tendon repairs were eligible for review. This included 136 minimally invasive repairs and 141 conventional open repairs. On analysis, there was no significant difference between the two surgical approaches in respect to the incidence of re-rupture, tissue adhesion, sural nerve injury, deep infection and deep vein thrombosis (p > 0.05). However, MIS had a significantly reduced risk of superficial wound infection, with three times greater patient satisfaction for good to excellent results compared with conventional open surgical approaches.
