  • This retrospective study is designed to compare the clinical results of tibial tuberosity transposition (TTT) and anti-rotation suture (ARS) treatments for medial patellar luxation (MPL). Medical records of 133 dogs were reviewed that had undergone surgical correction of MPL between January 2013 and May 2017. MPL correction was performed on 182 stifles, with TTT and ARS being performed on 101 stifles and 81 stifles. The common dog breeds receiving surgical treatment for MPL were Maltese, Pomeranian, Chihuahua and Poodle. Mean age of dogs with MPL was 32.6 months, and their mean body weight was 4.26 kg. Seventy dogs (52.6%) were male and 63 (47.4%) were female. Of the 182 stifles with MPL, grade II, III and IV were 18.7%, 72.0% and 9.3%. Total complications after TTT and ARS were recorded in 16.8% and 29.6%. Major complications after TTT and ARS were recorded in 5.9% and 12.3%, minor complications after TTT and ARS were recorded in 10.9% and 17.3%. The risk of complication and reluxation rate after TTT were significantly lower than that for ARS (p < 0.05). However, the rate of reluxation among dogs treated by ARS (1.2%) for grade II MPL was significantly lower than that for dogs treated by ARS (8.6%) for grade III MPL (p < 0.05). The TTT group had a shorter recovery period after surgical intervention than that in the ARS group (p < 0.001). In conclusion, TTT had a significantly lower incidence of complication and a shorter recovery period than ARS. However, ARS for grade II MPL appears to be a good surgical option for reducing the rate of reluxation after surgery. These results of this study could be used to provide therapeutic guidelines for surgical MPL correction in small-breed dogs.

  • The mouse kidney transplantation model serves as an invaluable tool for exploring various aspects of the transplant process, including acute rejection, cellular and humoral rejection, ischemia-reperfusion injury, and the evaluation of novel therapeutic strategies. However, conducting venous anastomosis in this model poses a significant challenge due to the thin and pliable characteristics of the renal vein, which often obstruct clear visualization of the resected vein's edge. This study proposes the adoption of a two stay suture technique to enhance the visualization of the renal vein's edge, thereby facilitating efficient and successful venous anastomosis. A total of 22 mice served as kidney donors in this study. The conventional anchoring suture technique was employed for venous anastomosis in 11 of these mice, while the remaining 11 underwent the two stay suture technique. The anastomosis duration and completion rates were then compared between these two groups. The conventional anchoring suture technique yielded an average anastomosis time of 29 minutes and a completion rate of 64%. In contrast, the two stay suture technique demonstrated a substantial improvement, with an average anastomosis time of 14 minutes and a completion rate of 100%. The two stay suture technique offers a promising solution to enhance visualization during venous anastomosis in murine kidney transplantation. This technique may particularly benefit novices by enabling them to perform venous anastomosis more easily, swiftly, and successfully.

  • The Akin osteotomy is a complimentary procedure in hallux valgus surgery. Surgical techniques may vary depending on the operators or fixation devices. Suture fixation, for which a removal procedure is not necessary, can often be recommended. However, there is a risk of failure due to the thin cortex of the phalanx. We describe a new technique using Ethibond suture fixation in Akin osteotomy, which can lower the risk of phalangeal cortical failure and articular cartilage irritation. First, the Akin osteotomy was performed on the proximal phalanx 5 to 6 mm distal to the first metatarsophalangeal joint. Then bone holes were drilled from dorsum to plantar parallel to osteotomy with the Kirschner wire. The final procedure involved passing the Ethibond sutures connected to a straight needle through the holes and tying it. This fixation method offers an effective and easy technique for performance of Akin osteotomy.

  • Purpose: The purpose of this study was to evaluate the tensile strength of surgical synthetic absorbable sutures over a period of 14 days under simulated oral conditions. Methods: Three suture materials (polyglycolic acid [PGA], polyglactin [PG] 910, and poly (glycolide-co-${\epsilon}$-caprolactone) [PGC]) were used in 4-0 and 5-0 gauges. 210 suture samples (35 of each material and gauge) were used. All of the samples were tested preimmersion and 1 hour and 1, 3, 7, 10, and 14 days postimmersion. The tensile strength of each suture material and gauge was assessed. The point of breakage and the resorption pattern of the sutures were also assessed. Results: During the first 24 hours of immersion, all 4-0 and 5-0 samples of PGA, PG 910, and PGC maintained their initial tensile strength. At baseline (preimmersion), there was a statistically significant (P<0.001) difference in the tensile strengths between the 4-0 and 5-0 gauge of PGA, PG 910, and PGC. PGA 4-0 showed the highest tensile strength until day 10. At 7 days, all the 4-0 sutures of the three materials had maintained their tensile strength with PGA 4-0 having significantly greater (P=0.003) tensile strength compared to PG. Conclusions: 4-0 sutures are stronger and have greater tensile strength than 5-0 sutures. The PGA 4-0 suture showed the highest tensile strength at the end of day 10.

  • For its lowerlid entropion correction, nonsurgical eyelid suture or surgical eyelid suture can be employed. Different types of surgical eyelid suture such as the Hotz method and the Callahan method, are generally performed, but were not sufficient for correcting of entropion. In our hospital we performed modified skin-tarsal fixation on 15 patients, 5 male and 10 female from January 20, 1999 to December 16, 2002. We corrected lower eyelid entropion with the excision of the skin and orbicularis oculi muscle and buried suture of tarsal plate and dermis which is a variant of the Callahan method. All the patients were satisfied with the operation results, and there was no case of recurrence of the lower eyelid pricking the cornea. During the 6 months period after the operation, the lower eyelids slightly turned inward but there was no further progression. The correction was performed excessively, therefore there was no case of recurrence after the operation and the results were satisfactory. There developed a dimple at the suture margin caused by skin contraction but it usually disappeared within 2 months after the operation. To avoid recurrence and to achieve satisfactory results, the orbicularis oculi muscle must be totally resected at the ciliary margin. We resected ciliary as well as pretarsal portion of orbicularis oculi muscle. Also, since most of the recurrences are originated from the medial side, the medial portion of skin flap must be tightly fixed to avoid recurrence and the upper part of the dermis should be fixed tightly to the lower border of the tarsal plate.

  • Naso-orbito-ethmoidal (NOE) fractures are complicated fractures of the mid-face. The treatment of NOE fractures is challenging and a comprehensive treatment strategy is required. We introduce a case of NOE fracture treated with open reduction and suspension sutures. A 28-year-old woman presented with a unilateral NOE fracture. To reduce the frontal process of the maxilla, a suspension suture was made by pulling the fragment using a double arm suture via a transcaruncular incision. The suture thread was placed in the horizontal plane. Another suspension suture on the inferior orbital rim assisted reduction procedure, and they passed through the overlying skin. The reduction alignment could be finely adjusted by tightening the transcutaneous suture threads while checking the degree of bone alignment through the subciliary incision. The two suture threads were suspended using a thermoplastic nasal splint. An additional skin incision on the medial canthal area, which would have resulted in a scar, could be avoided. Four months postoperatively, computed tomography showed an accurate and stable reduction. The patient was satisfied with her aesthetic appearance, and functional deficits were not present.

  • Acute Achilles tendon rupture is a frequent injury during sports and recreational activities. Treatments for Achilles tendon rupture have been controversial in recent decades. Traditionally the surgical treatment had benefit over nonsurgical treatment in terms of low rerupture rate and early functional restoration. Recently, nonsurgical treatment was found to show no statistically significant inferiority in re-rupture rate, functional outcome, and calf strength. Whereas, surgical treatment had some complications including adhesion, nerve injury, and infection. Nonsurgical treatment has been increasing due to functional rehabilitation with early weight bearing and restricted early motion. It focuses more attention on the course of caring for patients with deep discussion. There are open repair and minimally invasive repair in terms of surgical treatment. There are various techniques for minimally invasive repair of Achilles tendon, which has some advantages over the open repair. However, the optimal technique for minimally invasive repair has not been established. The number of suture strands is important regardless of suture technique.

  • We describe surgical sutures enabled with the local, sustained delivery of a TGF-${\beta}$ inhibitory drug, tranilast. To fabricate drug-delivery sutures, we separately prepared a tranilast-loaded strand using poly (lactic-co-glycolic acid), which was then physically braided with a surgical suture already in clinical use. By this method, the drug-delivery sutures maintained the mechanical strength and allowed the modulation of drug release profiles by simply altering the tranilast-loaded strand. The drug-delivery sutures herein released tranilast for up to 14 days. When applied to animal models, scarring was indeed reduced with diminished TGF-${\beta}$ expression and fibroblast numbers during the entire 21 day testing period.
