Cates NK, Wagler EC, Chen S, et al. - This study was conducted to present the retrocalcaneal enthesophyte resection with functional lengthening of the Achilles tendon and buried knot technique. Researchers included a total of fourteen patients (14 limbs) who had undergone retrocalcaneal enthesophyte resection with functional Achilles tendon lengthening, (8/14) of which had difficulty wearing shoe gear, (10/14) had edema, and (2/14) had erythema preoperatively. The results demonstrate that this method helps prevent short-term complications and long-term recurrence due to the functional lengthening mitigating insertional forces on the Achilles tendon.
