Purpose: This study compared the clinical outcomes of open repair, percutaneous repair, and minimal incision repair by Achillon in ruptured Achilles tendon. Materials and Methods: The outcomes of 12 patients with open repair (group 1), 8 patients with percutaneous repair (group 2), and 10 patients with minimal incision repair by Achillon (group 3) from February 2013 to March 2016 were analyzed retrospectively. The postoperative clinical evaluations were done by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Arner-Linholm scale, mid-calf circumference difference, one-leg heel raise difference, visual analogue scale (VAS) for postoperative scarring, time to return to work, and complications. Results: No significant difference in the AOFAS ankle-hindfoot score, Arner-Linholm scale, and time to return to work was observed among three groups (p=0.968, 0.509, and 0.585). The mean differences in the mid-calf circumference in groups 1, 2, and 3 were 1.09, 0.73, and 0.58, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.002). In addition, the mean VAS scores for postoperative scarring in groups 1, 2, and 3 were 7.0, 9.1, and 9.1, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.001). The mean differences in one-leg heel raising in groups 1, 2, and 3 were 2.03, 1.91, and 1.33, respectively; group 3 was significantly higher than groups 1 and 2 (p=0.010). The complications encountered were one case of deep infection in group 1 and one case of sural nerve hypoesthesia in group 2. Conclusion: Minimal incision repair by Achillon is recommended as an effective surgical treatment for Achilles tendon rupture because it minimizes the risk of complications, leads to an improved tendon strength and healing, and achieves cosmetic satisfaction.

Propose: There have been many debates about the ideal surgical technique for acute Achilles tendon rupture. The purpose of this study is to review and analyze the clinical outcome of the acute Achilles tendon ruptures that had been repaired by indirect suture technique with minimal incision that utilized an instrument called Achillon (Newdeal, France). Materials and Methods: This study is based on the 14 cases (14 patients) of acute Achilles tendon total ruptures that have been repaired by minimal incision technique utilizing Achillon instrument from June 2003 to December 2004. Two cases were reruptured before 8 weeks and repaired again using Krackow suture which left 12 feet for postoperative functional evaluation with at least 6 months of follow-up. Ten cases were men and average age at time of injury was 34.4 (26-49) years. The time from injury to surgery was an average of 4.5 (1-9) days and the postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. The ability to return to original work and sports activities as well as patient satisfaction were also evaluated. Results: The follow-up period was averaged for 13.2 (6-24) months. Seventy-one percent of cases were ruptured during sports activities. The ruptured level was the average of 5.1 cm (3.2-8 cm) above calcaneal attachment and the skin incision was averaged for 2.7 cm (2.5-3.0 cm) long. At final follow-up, standing on tip-toe was possible in all cases while the heel-floor height on ruptured side was shorter by 0.7 cm (0-2 cm). By Arner-Lindholm evaluation scale, 9 cases were excellent, and 3 cases were good. Overall AOFAS score was an average of 96.1 (94-100), and all patients were satisfied with the result. Patients returned to work at an average of 1.3 months after the surgery and pre-injury sports activities were all possible from at 6 months after operation. Conclusion: Since we have treated acute Achilles tendon ruptures with minimal incision technique utilizing the Achillon and gained encouraging functional results with all patients returning to previous work with high patient satisfaction, this technique could be recommended as one of the ideal surgical options for the Achilles tendon ruptures.

Purpose: Good results using minimal invasive hallux valgus surgery has been reported recently. We evaluate the usefulness of linear distal metatarsal osteotomy with minimal skin incision in mild and moderate hallux valgus deformity. Materials and Methods: Twenty-eight patients (thirty-one cases) who had mild to moderate hallux valgus deformity and underwent linear distal metatarsal osteotomy using minimal skin incision were evaluated between February 2005 and February 2006. Hallux-metatarsophalangeal-interphalangeal scale of AOFAS (American Orthopaedic Foot and Ankle Society) score was used as clinical evaluation. Preoperative, postoperative, after pin removal, and final follow up plain radiographs were used as radiologic evaluation. Results: Twenty-six cases (83%) among thirty-one cases showed more than average satisfaction, Average AOFAS score were improved from 63.2 points (range 45-74 points) to 86.4 points (range 67-93 points). Preoperative radiologic index of IMA $14.0^{\circ}$ (range $10-18^{\circ}$), HVA $30.2^{\circ}$ (range $19-39^{\circ}$), DMAA $13.8^{\circ}$ (range $5-23^{\circ}$) were improved postoperatively as IMA $8.3^{\circ}$ (range $5-10^{\circ}$), HVA $10.5^{\circ}$ (range $2-20^{\circ}$), DMAA $7.2^{\circ}$ (range $0-14^{\circ}$) correctively. Mean operative time was 15.5 minutes (range 11-18 minutes) and mean operative time was 5.6 days (range 2-8 days). Conclusion: Despite small skin incision and short operative time and admission period, linear distal metatarsal osteotomy with minimal skin incision showed similar results with conventional distal metatarsal osteotomy. Thus, it was thought to be useful operation in mild and moderate hallux valgus deformity.

Purpose: Minimal incision distal metatarsal osteotomy (MIDMO) is known to be an effective surgical procedure for mild to moderate hallux valgus. However, the result of MIDMO on moderate to severe hallux valgus is controversial; therefore, we investigated the radiological and clinical results of MIDMO on moderate to severe hallux valgus. Materials and Methods: We reviewed 51 feet (48 patients) with moderate to severe hallux valgus. The mean age was 67.0 years and the mean follow-up period was 32.2 months. Radiological data of hallux valgus angle, first intermetatarsal angle, and distal metatarsal articular angle on plain radiographs were analyzed. Recurrence, union, lateral translation of distal fragment and angulation were also analyzed. The clinical data were obtained using American Orthopaedic Foot and Ankle Society (AOFAS) score of preoperation and last follow-up. Receiver operating characteristic (ROC) curve was used to determine a cut-off value. Results: The mean hallux valgus angle measured at preoperation was $37.7^{\circ}$ and $15.9^{\circ}$ at last follow-up. The mean first intermetatarsal angle of preoperation and last follow-up were $15.2^{\circ}$ and $8.3^{\circ}$. The mean distal metatarsal articular angle changed from $12.6^{\circ}$ at preoperation to $7.8^{\circ}$ at last follow-up. Preoperative hallux valgus angle (p=0.0051) and distal metatarsal articular angle (p=0.0078) were statistically significant factors affecting postoperative AOFAS score. Cut-off value of each was $37^{\circ}$ and 13o, respectively. Lateral translation of distal fragment in 5 recurrent cases was 23.0% compared to 45.3% of 46 non-recurrent cases. The result was statistically significant and the cut-off value was 38%. Conclusion: Sufficient lateral translation over 38% in MIDMO on moderate to severe hallux valgus patients with preoperative hallux valgus angle under $37^{\circ}$ and distal metatarsal articular angle under $13^{\circ}$ can lead to good clinical results without recurrence.
