  • 10 patients with mitral regurgitation associated with various congenital cardiac anomalies were treated by reconstructive techniques in the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the period of 2 years from 1982 to 1984. There were mitral valvular cleft in one case, chordae tendineae rupture associated with congenital multiple cardiac-anomalies [VSD, PDA, prolapse of aortic non-coronary cusp through VSD] in one case, elongated chordae tendineae after removal of left atrial myxoma in one case, and mitral annular dilatation associated with VSD in 3 cases, large PDA in 2 cases, aortic regurgitation [bicuspid valve] in one case, and unknown origin in one case. Owing to the various pathology above mentioned, reconstructive surgical approach to mitral incompetence is accordingly complicated and a combination of the following different procedures were properly used case by case, that is, suture of chordae tendineae, shortening of elongated chordae tendineae, closure of VSD, ligation of PDA, aortic valvuloplasty, mitral annuloplasty with mattress suture, etc. All patients were survived and they have been excellent postoperative results.

  • Background: Nasal septal cartilage is used to obtain favorable aesthetic and functional outcomes in rhinoplasty, but is often difficult to harvest or the harvested amount is insufficient. Therefore, the objective of this study is to introduce how to harvest septal cartilage optimally without losing and use harvested cartilage efficiently. Methods: From March 2015 to January 2020, we tried to harvest as much septal cartilage as possible while maintaining the L-strut in 30 patients. A spreader flap and septal rotation suture were used instead of a spreader graft. Also in patients who needed a spreader graft and septal extension graft, a spreader graft was used on one side and a one-piece spreader graft combined with a septal extension graft was performed on the other side. For tip plasty, a columella septal suture was performed first. Postoperative patient satisfaction was assessed using the Rhinoplasty Outcome Examination questionnaire. Results: No serious complications were observed. The patient satisfaction score was 50% or above in 27 patients (90%) and less than 50% in only three patients (10%). The average score was 81.5 points. Conclusion: For septal cartilage deficiency, a spreader flap, the septal rotation suture, or onepiece spreader graft combined with a septal extension graft was used. The nasal tip was sufficiently rotated using the columellar septal suture technique first. These techniques made it possible to obtain good aesthetic outcomes using only septal cartilage, without harvesting other cartilage.

  • The present study aimed to document the biomechanical findings of soft tissue reconstruction surgeries for the treatment of medial patellar luxation in dogs. Stifle joints (n = 12) from dogs weighing 4.1-8.4 kg were used in this study. The following soft tissue reconstruction techniques used for the treatment of medial patellar luxation were selected for this study: vastus medialis release, medial retinacular release, and capsule release for medial realignment (n = 6), and retinacular imbrication and anti-rotational suture for lateral realignment (n = 6). A 5-kg traction using an electronic scale was applied at $45^{\circ}C$ laterally for medial realignment and medially for lateral realignment. Fluoroscopic imaging was used to measure the length of patellar displacement (LPD) in each technique. Among medial realignment techniques, capsule release had the highest horizontal LPD; vastus medialis release had significantly higher horizontal LPD than medial retinacular release. Vastus medialis release had the smallest increase statistically in vertical LPD, and vertical LPD did not differ significantly between medial retinacular and capsule release. Among lateral realignment techniques, the horizontal LPD was significantly higher in anti-rotational suture with retinacular imbrication than in retinacular imbrication alone, but the vertical LPD did not differ significantly between the two groups. Our findings indicated that vastus medialis release could decrease the medial tension on the patella without inducing patellar instability in dogs. Both medial retinacular and capsule release could increase patellar instability; moreover, medial retinacular release does not decrease the medial tension on the patella. Antirotational suture with retinacular imbrication provides more lateral tension than retinacular imbrication alone.

  • Purpose: Constricted ear, which is named by Tanzer includes lop ear, cup ear, and sort of prominent ear. It has classified three groups by Tanzer, especially grou I and IIA have been corrected by banner flap, Musgrave's technique, tumbling concha - cartilage flap, reversed banner flap and others. However, these techniques were too invasive for correcting mild degree of deformity. Therefore, we corrected the ear with mattress suture which is simple and less invasive. Method: The operations were done against 5 patients from 2005 March to 2008 April. All the cases were unilateral ears with constriction included helix and scaphoid fossa without difference in length between both ears. Though a posterior auricular skin incision, the folded cartilage is exposed and two parallel incisions on superior crus were made. After mattress suturing in cartilage, the superior crus of antihelix was formed and its force enables the folded portion to be in a normal anatomic position. Result: All of 5 patients got satisfactory results. There were no complications like hematoma or skin necrosis, and no recurrence during follow - up period(the average period was 9 months). And we couldn't recognize the difference between height of both auricles. Conclusion: Mattress suture is simple, less invasive, and suitable on correcting mild deformity of constricted ear with better result, so here we suggest the method.

  • 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.

  • 다양한 이두근 건고정술이 시행되고 있어서, 문헌들의 결과를 단순 비교하기 어렵게 만든다. 이두근 장두의 건고정술은 첫째로, 시술을 관혈적 절개를 통하여 시행하는가 또는 관절경을 이용한 방법으로 시행하는가로 구분해 볼 수 있다. 두 번째로는, 이두건 자체를 고정하는 주변 조직에 따라서 연부 조직 건고정술과 골 고정술로 나눌 수 있다. 세 번째로는, 고정하는 위치에 따라 근위부와 원위부로 구분할 수 있다. 네 번째로는, 건 고정술에 기구(간섭 나사, 봉합 나사, 비매듭 봉합 나사 등)를 사용하는 가에 따라서 구분해 볼 수 있다. 적절한 고정력이 어느 정도인지 밝혀지기까지는 단정적인 결론은 보류되어야 한다.

  • The arthroscopic rotator cuff repair is now considered a mainstream technique with highly satisfactory clinical results. However, concerns remain regarding healing failures for large and massive tears and high revision rate. In recent decades, various repair strategies and construct configurations have been developed for rotator cuff repair with the understanding that many factors contribute to the structural integrity of the repaired construct. The focus of biomechanical test in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. These include repaired rotator cuff tendon-footprint motion, increased tendon-footprint contact area and pressure, and tissue quality of tendon and bone. Recent studies have shown that a transosseous tunnel technique provides improved contact area and pressure between rotator cuff tendon and insertion footprint, and the technique of using double rows of suture anchors to recreate the native footprint attachment has been recently described. The transosseous equivalent suture bridge technique has the highest contact pressure and fixation force. In this review, the biomechanical tests about repair techniques of rotator cuff tear will be reviewed and discussed.

  • Syndesmotic injuries are found frequently in clinical practice, and they remain controversial because of the variety of diagnostic techniques and management options. Bony avulsions or malleolar fractures are commonly associated with syndesmotic disruptions. Even unstable isolated syndesmosis injuries are associated with a latent or frank tibiofibular diastasis and should not be ignored in the early phase. A relevant instability of the syndesmosis with diastasis results from collateral ligaments tears and requires operative stabilization. The treatment involves an anatomic reduction of the distal tibiofibular articulations followed by stable fixation. Syndesmotic transfixation screws or suture button implants are being proposed as a means of fixation. Recently, suture button fixation has shown more favorable outcomes, but the outcomes can still be controversial. Syndesmotic malreduction can lead to hardware failure, adhesions, heterotopic ossification, tibiofibular synostosis, chronic instability, and posttraumatic arthritis. In particular, the correct diagnosis and evidence-based treatment options for unstable syndesmotic injury should be considered.
