Abstract |
Introduction |
One treatment option in insertional Achilles tendinopathy is open reconstruction of the insertion, resecting the enthesophyte and posterosuperior calcaneal prominence and reinserting the tendon using anchors. Although classically performed as an open procedure, the necessary subcutaneous release and dissection can entail problems of healing in at-risk patients.
Hypothesis |
It is possible to perform Achilles disinsertion-reinsertion with posterosuperior calcaneal prominence resection endoscopically, without iatrogenic risk, enabling complete resection of the enthesophyte and posterosuperior calcaneal prominence and satisfactory reinsertion.
Material and methods |
An operative technique was developed, consisting in Achilles disinsertion-reinsertion with resection of the posterosuperior calcaneal prominence and enthesophyte endoscopically via 5 portals. A feasibility study was conducted in an anatomy laboratory on 10 foot specimens, assessing iatrogenic impact. Bone resection quality was assessed under endoscopic and fluoroscopic control. Reinsertion quality was assessed endoscopically and on dissection of the specimens.
Results |
In the 10 procedures, there were no failures. Resection of the calcifications and the calcaneal prominence was complete in all cases. Reinsertion was satisfactory in all cases. There were no iatrogenic neural lesions.
Discussion/Conclusion |
It was possible to perform endoscopic Achilles disinsertion-reinsertion with resection of the posterosuperior calcaneal prominence and enthesophyte. The procedure did not seem to increase iatrogenic risk, and enabled complete bone resection and satisfactory reinsertion. This endoscopic technique now needs to be validated clinically, with comparison versus open surgery.
Level of evidence |
IV; cadaver study.
