Abstract
Purpose: This work revealed the advantages of percutaneous suture of the Achilles tendon using an improved technique with entirely resorbable material.
Material and methods: Thirty cases of subcutaneous tears were operated on two to ten days after the accident (range 24 hr – 7 weeks). We used a 4-thread resorbable V-suture anchored in the calcaneum and, after blocking the ankle in the equine position, on the proximal fragment using two bioresorbable buttons. Postoperatively, immediate weight bearing was progressive using an adjustable and removable orthesis. Active-passive rehabilitation was initiated immediately. The material was left in place indefinitely and was resorbed after three months.
Results: We followed these patients for 24 – 8 months. Wound healing was excellent and material tolerance was exceptional (only one complaint of transient calcaneal pain). Objective outcome was comparable with that obtained with conventional suture, with a significant reduction in the risk of skin and neurological complications. There were no cases of recurrent tears. CT and MRI controls confirmed the early healing, the quality of the tendon repair, and material resorption within the expected delay. Subjective outcome was excellent.
Discussion: While the results obtained in this series are comparable to those with prior percutaneous techniques, the important improvement was the very significant reduction in skin and neurological complications often reported in other series. It is also noteworthy that there were no recurrent tears. The advantages are even more remarkable compared with surgery. The greater solidity authorises very rapid rehabilitation, similar to protocols advocated for nonoperative care. The limitations on indications appear to be tears seen after three weeks and true calcaneal de-insertions.
Conclusion: This technique improves patient comfort and follow-up while allowing safer rehabilitation.
