Background. Chronic Achilles tendon rupture is usually misdiagnosed and treated improperly. This study aims to better understand the treatment of chronic Achilles tendon rupture. Methods. Patients who were not able to perform a single-limb heel rise were chosen. Pre- and postoperative magnetic resonance imaging (MRI) were conducted. By evaluating the presence or absence of Achilles tendon stumps and the gap length of rupture, V-Y advancement, gastrocnemius fascial turndown flap, or flexor halluces longus tendon transfer were selected for tendon repair. The function of ankle and foot was assessed by American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores and Achilles Tendon Total Rupture Score (ATRS). Results. Twenty-nine patients were followed up. One patient had superficial incision infection, which was healed after debridement and oral antibiotics. Three months postoperatively, MRI showed some signs of inflammation, which disappeared at one or two years postoperatively. All patients were able to perform a single-limb heel rise. Mean AOFAS scores and ATRS scores were increased at the latest follow-up. Conclusion. Surgical options can be determined by evaluating the presence of the Achilles tendon stumps and the gap length, which can avoid using the nearby tendon and yield satisfactory functional results.
Objective To evaluate the surgical results of V‐Y tendon plasty in the treatment of chronic Achilles tendon rupture during medium and long‐term follow‐up. Methods Between June 2005 and September 2017, 20 patients with chronic Achilles tendon rupture underwent V‐Y tendon plasty in our hospital. The mean injury‐to‐surgery time was 20.4 weeks (range, 4–96 weeks). The Matles test and an improved Thompson test was used to examine Achilles tendon rupture. These patients were not able to stand on the tiptoes of the injured lower extremity. X‐ray tests ruled out the chance of fracture and were used to examine the Kager triangle. MRI was used to confirm the final diagnosis. The function of the ankle and the foot was assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Achilles Tendon Total Rupture Score (ATRS). V‐Y tendon plasty for Achilles tendon reconstruction was performed. A below‐knee cast was used to keep the ankle in plantar flexion (up to 20°) for 4 weeks. Non‐weight‐bearing exercise was allowed with crutches. After 4 weeks, partial weight‐bearing was allowed. Physical exercises were performed under rehabilitation guidelines. At 10–12 weeks postoperation, patients began to return to daily life activity levels without restrictions. Preoperative and postoperative MRI was obtained. Results The mean follow‐up period was 32.8 months. The mean operative gap of the Achilles tendon after debridement was 5 cm (range, 4–9 cm), with 85% of the gap less than or equal to 6 cm. The mean AOFAS score increased from 59.25 ± 12.28 preoperatively to 96.55 ± 3.75 at final follow‐up ( P < 0.05). The mean ATRS score increased from 39.55 ± 14.21 preoperatively to 94.05 ± 4.89 at final follow‐up ( P < 0.05). All patients had no recurrent Achilles tendon rupture during the follow up. No patient had developed serious complications, such as sural nerve injury or deep vein thrombosis. Patients were able to return to daily life activity levels without restrictions. At the latest follow‐up, all patients were able to perform repetitive single heel rise on the involved limb, and to walk without a visible limp. All of the postoperative MRI showed the continuity of the Achilles tendon with no signs of cysts or inflammation, indicating perfect healing at the final follow‐up. Conclusions V‐Y tendon plasty can be used in most cases of chronic Achilles tendon rupture. It yields satisfactory functional results and low complication rates. The advantage of this procedure is that it is an easy and economic method without the need for expensive synthetic implants. V‐Y tendon plasty should be considered an acceptable first‐choice treatment.
Background Both percutaneous Achilles tendon lengthening by triple hemisection and the traditional open Z-lengthening are effective methods for Achilles tendon contracture. This study aims to evaluate the efficacy and safety of this new therapeutic method, which is based on the percutaneous sliding technique with three hemi-cuts in the tendon, as compared with the traditional open Z-lengthening. Methods Retrospective analysis of the Achilles tendon contracture cases in our hospital between January 2010 and September 2016 was conducted. Twenty-five cases received percutaneous Achilles tendon lengthening (group A), and 30 patients who underwent open Z-lengthening during the same period were in the control group (group B). Operative time and hospital stay were statistically analyzed. Incision complication, equinus recurrence rate and Achilles tendon rupture morbidity were recorded. The function was assessed by American Orthopaedic Foot & Ankle Society (AOFAS) score. All cases in group A received Magnetic Resonance Imaging (MRI) of ankle preoperatively and in the follow-ups. Results The mean follow-up period was 42.04 months in group A and 61.7 months in group B. The entire operative time and the mean hospitalization days were lower in group A than in group B. No incision and infection complication occurred in group A. The infection rate in group B was 3.3%. Equinus recurrence rate was 4% in group A and the equinus recurrence rate in group B was 21.4%. In group A, the mean AOFAS score increased from 64 ± 10.16 points preoperatively to 96.08 ± 3.17 at final follow-up, while the score in group B increased from 63.48 ± 6.2 points to 85.4 ± 10.3. MRI showed continuity of the Achilles tendon and homogeneous signal in group A. Conclusion Modified surgery can significantly reduce the risk of Achilles tendon rupture, provide better balance in soft tissue strength between ankle dorsiflexion and ankle plantarflexion, helping to avoid recurrence of the deformity.
