The purpose of this study was to determine the effects of elbow joint angle on mechanical properties, as represented by ultimate load, failure strain and elastic modulus, of bone-tendon specimens of common extensor tendon of the humeral epicondyle. Eight pairs of specimens were equally divided into two groups of 8 each, which selected arbitrarily from left or right side of each pair, positioned at 45$^{\circ}$ and 90$^{\circ}$ of elbow flexion and subjected to tension to failure in the physiological direction of the common extensor tendon. For comparison of the differences in the failure and elastic modulus between tendon and the bone-junction, data for both were evaluated individually. Significant reduction in ultimate load of bone-tendon specimens was shown to occur at 45$^{\circ}$. The values obtained from the bone-tendon junctions with regard to the failure strain were significant higher than those from tendon in both loading directions, but the largest failure strain at the bone-tendon junction was found at 45$^{\circ}$. The elastic modulus was found to decrease significantly at the bone-tendon junction when the loading direction switched from 90$^{\circ}$ to 45$^{\circ}$. Histological observation, after mechanical tensile tests, in both loading directions showed that failure occurred at the interface between tendon and uncalcified fibrocartilage in the thinnest fibrocartilage zone of the bone-tendon junction. We concluded that differences in measured mechanical properties are a consequence of varying the loading direction of the tendon across the bone-tendon specimen.

The triangular fibrocartilage complex (TFCC) is crucial for stabilizing the ulnar side of the wrist but can be partially torn due to degenerative changes, falling, or sudden injuries. However, only a few studies have focused on the use of Korean medicine treatments for TFCC-related wrist pain. This case report presents the successful outcomes of integrated Korean medicine treatment in a patient with a partial TFCC tear. The diagnosis was confirmed via magnetic resonance imaging, which revealed the tear. Subsequently, the patient received integrated Korean medicine treatments. The assessment of the pain scale scores revealed a significant reduction in wrist pain and an improvement in daily life activities. Based on the findings of this study, integrated Korean medicine treatments have been proven to be an effective treatment option for patients with a partial TFCC tear. However, further research is needed to determine the potential benefits and mechanisms of these treatments in managing TFCC-related wrist pain.

Objectives The purpose of this study is to analyze the trends in domestic and international clinical research on the Korean medicine for triangular fibrocartilage complex (TFCC) injuries and to contribute to future domestic research. Methods In this study, clinical studies on TFCC injuries treated with Korean medicine were searched through databases such as Research Information Sharing Service, ScienceON, DBpia, China National Knowledge Infrastructure, PubMed, Medline, and Embase. Fifteen clinical studies were selected, of which publication years, intervention methods, assessment tools, and various other factors were analyzed, including potential side effects. Results Among the selected 15 studies, total of 13 intervention methods were used. Electroacupuncture was the most frequently used method (40%), followed by herbal medicine (33%), acupuncture (26.7%), chuna manual therapy (26.7%), pharmacopuncture (20%), acupotomy (13%), herbal ointment (13%), hot medicinal compress therapy (13%) and etc. Most studies showed that Korean medicine treatments effectively alleviated TFCC injuries, with visual analogue scale being the most commonly used assessment tool. Conclusions Korean medicine treatments for TFCC injuries appears to be effective; however, further research is needed to enhance understanding. Large-scale clinical trials comparing the efficacy of Korean medicine treatments, along with investigations into side effects and recurrence rates are necessary. By doing so, the safety and efficacy of Korean medicine treatments for TFCC injuries can be further established.

Purpose : To evaluate the efficacy of arthroscopic management of the triangular fibrocartilage complex(TFCC). Materials and Methods : Thirteen patients(14 wrists) with acute or chronic traumatic triangular fibrocartilage complex lesions were included in the study. The mean patients' age was 28.3 years, with a range of 21 to 45 years. All patients were diagnosed by physical examination, arthrographic or magnetic resonance imaging studies. Eight of the 14 wrists had central TFCC tear while 6 wrists had peripheral tear. Under arthroscopic control, injuries to the central portions were treated by debridement and excision of unstable tissue fragment while peripheral tears were repaired. The follow-up period averaged 28 months. The results were analyzed clinically using the Mayo modification of the Green and O' Brien wrist scoring system. Results : Nine of the 14 wrists were rated excellent,3 good and 2 fair Overall, 12 of the 14 patients rated as satisfactory and returned to sports or work activities. Conclusion : Arthroscopic treatment of TFCC resulted in a high degree of patient satisfaction and an increase in the ability to perform at workshop.

Purpose : To investigate arthroscopic simple excision for the treatment of osteochondritis dissecans of the talus and to examine gross change and histological evaluation of the defect through second look arthroscopy. Materials and Methods : This study included twenty-two patients who had osteochondritis dissecans of the talus that was treated with excision of arthroscopic loose body and necrotic bone tissue, leaving bleeding bed. In 7 cases, we performed second look arthroscopic examination for the evaluation of gross change of defects and histologic findings. Final results were evaluated with two clinical and functional protocols. Average follow up period was 42 months from 14 months to 8 years. Results : Ankle-hindfoot score (100 point) was improved significantly (p<0.003). Subjective and functional scores (100 points) averaged 82 points. The defect of lesion had a tendency of filling with fibrous tissue and fibrocartilage. Although the defect was filled with fibrocartilage, specific secondary lesion was not detected through second look arthroscopic examination. Conclusion : Arthroscopic debridement was an effective method for the treatment of osteochondritis dissecans of the talus without progression of secondary lesion even though the defect was filled with fibrocartilage.

Based on clinical observations, it is suspected that the bone-tendon origin is the site where piratical failure, leading to pathophysiological changes in the humeral epicondyle after repetitive loading, is initiated Mechanical properties and failure patterns of the common extensor and flexor tendons of the humeral epicondyle under static and repetitive loading have not been well documented. Our goal was to determine mechanical properties of failure strength and strain changes, to correlate strain changes and the number of cyclic repetitions, and to identify the failure pattern of bone-tendon specimens of common extensor and flexor tendons of the humeral epicondyle. Mechnaical properties of human cadaver bone-tendon specimens of the common extensor and flexor tendons of the humeral epicondyle were tested under two different loading rates. No statistically significant difference in ultimate tensile strength was found between male and female specimens or between slow (10 mm/sec) and fast elongation (100 mm/sec) rates. However, a statistically significant difference in ultimate tensile strength between the common extensor (1190.0 N/$cm^2{\pm}$388.8) and flexor 1922.0 N/$cm^2{\pm}$764.4)tendons was found (p<0.05). When loads of 25%, 33%, and 41% of the ultimate tensile strength of their contralateral sides were applied, the number of cycles required to reach 24% strain change for the common extersor and flexor tendons were approximately 8,893, 1,907, and 410, respectively. The relationship between cycles and loads was correlated ($R^2$=0.46) Histological observation showed that complete or partial failure after tensile or cyclic loadings occurred at the transitional zone, which is the uncalcified fibrocartilage zone between tendon and bone of the humeral epicondyle. Sequential histological sections revealed that failure initiated at the upper, medial aspect of the extensor carpi radialis brevis tendon origin. Biomechanical and hstological data obtained in this study indicated that the uncalcified fibrocartilage zone at the bone-tendon origin of the common extensor and flexor tendons is the weak anatomical structure of the humeral epicondyle.
