Background Delayed wound healing is a potention complication after Achilles tendon suture repair and occurs for various reasons. The conventional treatment for delayed wound healing is open surgery, but patients face long recovery times and postoperative care is difficult. Case Presentation This report presents three patients who were seen at our institute from April 2008 to October 2017 due to long‐term non‐healing wounds after surgery. All three patients had undergone surgery at least 2 months previously. We performed endoscopic surgery on these patients. After the operation, patients received less antibiotics and simpler care than would be required for conventional open surgery. There is no need to keep the wound open after the operation or perform wound cleaning for multiple times at the same time, which can reduce healing time. At the last follow up, all postoperative scores among the patients were significantly improved compared to before surgery. The Achilles tendon total rupture scores were excellent and the American Orthopedic Foot and Ankle Society scores were satisfactory, indicating improvements in Achilles tendon function and movement in patients after surgery. Conclusion Our case reports demonstrate that arthroscopic treatment for delayed wound healing after Achilles tendon suture repair is satisfactory and reliable; frequent opening of the wound for cleaning is not required after the operation, thus reducing the healing time.

Background This study was designed to investigate whether intraoperative electrical nerve stimulation has effects on the short-term recovery of cubital tunnel syndrome patients after ulnar nerve release. Methods Patients diagnosed as cubital tunnel syndrome were selected. At the same time, they received conventional surgery treatment. The patients were divided by a randomized digits table into two groups. The control group underwent conventional surgery, and the electrical stimulation (ES) group underwent intraoperative electrical stimulation. All the patients were tested for sensory and motor functions, grip strength, key pinch strength, motor conductivity velocity (MCV), and maximum compound muscle action potential (CMAP) before operation and 1 month and 6 months after operation. Results In patients treated with intraoperative ES, the sensory and motor functions and the strength of muscle were significantly improved after 1-month and 6-month follow-up than the control group. After the follow-up, the patients in the ES group had significantly higher grip strength and key pinch strength than the control group. After the follow-up, the patients in the ES group had significantly higher MCV and CMAP than the control group. Conclusion Intraoperative electrical stimulation of nerve muscle can significantly promote the short-term recovery of nerve and muscle functions after the surgery in cubital tunnel syndrome patients.
