Abstract:
Objective To compare the clinical effectiveness between the channel-assisted mini-invasion and open Achilles shortening for treatment of the elongated Achilles tendon following previous rupture.Methods The clinical data of 19 patients admitted from Dec. 2013 to Dec. 2015 and met the inclusion criteria were analyzed retrospectively. Eight patients were treated with shortening operation by channel-assisted minimally invasive repair system, while 11 patients received dissection of Krackow Achilles tendon shortening. There was no significant difference between the two groups in gender, age, injury to operation time, preoperative calf circumference and preoperative AOFAS (American Orthopaedic Foot & Ankle Society) score (P>0.05).Results The operation time, incision length and postoperative hospital days were significantly less in min-invasion group than in incision group (P<0.05). After operation, wound healing by first intention was obtained in incision group except 1 case which got infection and healed by treatment 2 weeks later. No sural nerve and vascular injury and lower extremity deep vein thrombosis existed. MRI showed that the Achilles tendon recovered in both groups at the 8th week follow-up. The patients were followed up for 12-17 months in the mini-invasion group and 12-20 months in the incision group. The calf circumference and AOFAS score of both groups were higher in the last follow-up than that in pre-operation (P<0.05), but no significant difference existed between the two groups at the last follow-up (P>0.05).ConclusionChannel-assisted minimally invasive Achilles tendon shortening operation has not only similar effectiveness to the incision shorting operation for the treatment of elongated Achilles tendon following previous rupture, but also has the advantages of shortening operation time and stay in hospital and avoidance of sural nerve injury.
