Ulnar collateral ligament injuries have been increasingly common in overhead throwing athletes. Ulnar collateral ligament reconstruction is the current gold standard for managing ulnar collateral ligament insufficiency, and numerous reconstruction techniques have been described. Although good clinical outcomes have been reported regarding return to sports, there are still several technical issues including exposure, graft selection and fixation, and ulnar nerve management. This review article summarizes a variety of surgical techniques of ulnar collateral ligament reconstructions and compares clinical outcomes and biomechanics.

Ulnar collateral ligament injuries of the elbow are frequent among overhead athletes. The incidence of ulnar collateral ligament reconstructions (UCLRs) in high-level players has increased dramatically over the past decade, but the optimal technique of UCLR is controversial. Surgeons need to manage the patients' expectations appropriately when considering the mode of treatment. This article reviews current studies on the management of ulnar collateral ligament injuries, particularly in overhead athletes.

Recurrent dislocation of elbow joint occurs relatively rarely by the injury of the collateral ligament which contributes elbow joint stability. Among them, posterolateral rotatory instability occurs by the injury to the lateral ulnar collateral ligament. We experienced a case of recurrent dislocation of elbow joint due to posterolateral rotatory instability. We treated operatively with lateral ulnar collateral ligament reconstruction using the palmaris longus tendon by technique of Nestor et al. We report it with literature analysis.

Forefoot injuries are common in runners or martial art athletes, but due to the anatomical stability, collateral ligament injury of the hallucal interphalangeal joint has been rarely reported. We report a college Taekwondo athlete with chronic varus instability of the hallucal interphalangeal joint due to chronic lateral collateral ligament rupture. The patient had been treated with lateral ligament reconstruction and achieved good clinical outcome.

Purpose: To report the results of arthroscope assisted posterior cruciate ligament reconstruction without tourniquet, which has not yet been reported in documents within the country. Materials and Methods: Out of the 75 cases of arthroscope assisted posterior cruciate ligament reconstruction on patients with posterior cruciate ligament damage from January, 1998 to May,2003 in this hospital, study was done on 49 cases of patients with isolated posterior cruciate ligament damage, excluding 16 cases of patients who were applied tourniquet in extraarticular operation due to combined damage such as in lateral collateral ligament and posterolateral collateral ligament, and 10 cases where the postoperative observation period was less than 12 months. There were 13 cases where reconstruction was done using autogenous bone-patella tendon-bone, 19 cases using allogenous bone-patella tendon-bone, and 17 cases using allogenous achilles tendon. For assessment, the 49 cases were compared using Lysholm knee scoring scale. Results: The average duration of operation was 105 minutes. There were no severe complications such as swelling, bleeding, infection etc . Assessment results attained by Lysholm knee scoring scale was 74(fair) for cases where autogenous bone-patella ten-don-bone was used,75(fair) for cases where allogenous achilles tendon was used, and 76(fair) for cases where allogenous bone-patella tendon-bone was used. Conclusion: There are no difficulties to perform the arthroscopic assisted posterior cruciate ligament reconstruction. Reconstruction without tourniquet can be thought to prevent complications that could follow when using it.

The PCL reconstruction in chronic isolate PCL reconstruction was still controversy. 1) In isolate PCL deficient knee, functionally not so bad as like ACL deficient knee. 2) The result of the PCL reconstruction was not as good as ACL reconstruction. Therefore, isolate PCL injuries has been treated as nonoperatively. Hey Grovere, who was the first to attempt an intra-articular reconstruction of the PCL, utilized the semi-tendinous tendon other static procedures have been described in only a few cases with very limited follow-up. Dynamic procedures utilizing the medial head of the gastrocnemius has been reported by Hugston and Degenhardt, Kennedy and Grainger, and Insall and Hood. These procedures did not improve static stability. Dr Clancy, who was introduce the use of BPTB for the PCL reconstruction transtibial and femoral tunnel. From 1995, untill early 1990 PCL reconstruction was done as tend as placement of the isometric point. Physiometic placement of Anatomical placement of the femoral tunnel in PCL reconstruction were introduced in 1995. Tibial Inlay Technique was reported by Dr Berg in 1995. The main advantage of the tibial Inlay Technique was to avoid fraying of the graft at the posterior tibial tunnel orifice. In complete PCL ruptured and severely posterior unstable knee, dual femoral tunnel technique will be to get better result than one bundle technique. To achieve restoration of normal posterior laxity, it is critical to address the posterior as well as the posterolateral structures. Futher research is necessary to evaluate new surgical approches such as double-bundle reconstructions and tibial inlay techniques as well as improved techniques for capsular and collateral ligament injuries.

Purpose: The purpose of this study was to evaluate the result of anterior cruciate ligament (ACL) reconstruction using a fourstrand single semitendinous tendon to decrease the donor site morbidity due to harvest both semitendinosus and gracilis tendon. Materials and Methods: Thirty seven consecutive patients who had underwent ACL reconstruction using four-strand single semitendinosus tendon were evaluated. Mean age was 28.6 years old. Male was 34, female 3 patients. Time from injury to surgery was 5.4 months. Combined injuries were 10 meniscus injuries, 3 medial collateral ligament injuries and 1 osteochondral injury. Mean follow-up period was 16 months(12~18 months). Clinical evaluation was done using range of motion, Lachman test, pivot-shift test, Lysholm score & KT-2000 arthrometer. Results: All patients showed the normal range of motion of mean 150..at follow-up. Lachman test and pivot-shift test was negative in 35 cases. Lysholm score was improve from 84 to 92. Two cases had residual laxity due to poor compliance. Mean anterior translation compared to contralateral side by KT-2000 arthrometer improved from 6.7 mm preoperatively to 2.1 mm at follow-up. Conclusion: Reconstruction of the anterior cruciate ligament with use of a four-strand single semitendinosus tendon autograft showed good clinical results.

The first metatarsophalangeal joint injury is common in professional soldiers and athletes. But this was rarely reported. A professional soldier has varus instability in the first metatarsophalangeal joint due to hyperextension. In the MR Imaging, weavy appearance in lateral collateral ligament and high signal change in plantar plate was shown. So he has surgical treatment using reconstructive procedure. At first, $4^{th}$ extensor digitorum longus tendon was splitted longitudinally and harvested, second triangular shape reconstruction on lateral joint line was done using harvested tendon. One year later, fifteen degrees was limited compared with intact side. Reconstruction using $4^{th}$ extensor digitorum longus tendon in traumatic dynamic hallux varus was good method.

Posterolateral rotatory instability is the most common pattern of elbow instability especially which is recurrent, and is usually post-traumatic because of inadequate soft tissue healing. The lateral ulnar collateral ligament was reconstructed by using ipsilateral palmaris longus tendon. Functionally good result was obtained. This is a case report illustrating the posterolateral rotatory instability of the elbow and its reconstruction with palmaris longus.
