Posterior root tear of the medial meniscus are well known. Although very rare, there are reports of anterior root tears of the medial meniscus but no reports on traumatic bony avulsion of the anterior medial meniscus root. This paper reports a case of an isolated bony avulsion of the anterior medial meniscus root, which was successfully repaired arthroscopically.

Purpose: To evaluate the usefulness of computerized tomography (CT) for the diagnosis and the fragment fixation of anteroinferior tibiofibular ligament avulsion fracture in ankle fracture. Materials and Methods: We retrospectively studied 108 patients with an ankle fracture who had been checked with plain radiographs and CT from July 2006 to July 2010. They were divided into two groups; patients with (19 patients) and without (89 patients) an avulsion fracture of anteroinferior tibiofibular ligament. The two groups were evaluated with Lauge-Hansen classification, the energy of trauma, and the radiologic indices for syndesmotic injury, and were compared each other. Average follow up periods of two groups were 25 and 23 months each. Those who were unstable at stress test during surgery were divided into fragment fixation of anteroinferior tibiofibular ligament avulsion fracture group (8 patients) and transfixation one (11 patients) according to treatment method. Clinical and radiological results at last follow up were also compared. Results: Fourteen avulsion fractures of anteroinferior tibiofibular ligament were diagnosed by CT only. Incidences of pronation-external rotation injury, high energy trauma, positive radiologic indices for syndesmotic injury were significantly higher in patients with an avulsion fracture of anteroinferior tibiofibular ligament than those without it. Clinical and radiological results were satisfactory in both groups at last follow up, and were not significantly different between them. Conclusion: In patients who have an ankle fracture by pronation-external rotation injury, high energy trauma, or with positive radiologic indices for syndesmotic injury, CT is useful for diagnosis of an avulsion fracture of anteroinferior tibiofibular ligament. Fragment fixation of anteroinferior tibiofibular ligament avulsion fracture is a useful treatment option for syndesmotic injury.

Avulsion fractures of the intercondylar eminence of the tibia are uncommon. This kind of fracture is most commonly found in adolescents, with an increasing incidence for those involved in competitive athletics. Recently, an arthroscopic procedure is preferred to reduce the operation-related morbidity. Screws, K-wires, Suture anchor have been described as fixation devices. Cannulated screw fixation is a simple method, but this instrument has the risk of causing damage to the growth plate. The authors report good results using cannulated screw in arthroscopic treatment for pediatric anterior cruciate ligament avulsion fracture.

An anterior cruciate ligament (ACL) avulsion fracture is an uncommon injury that occurs predominantly in the pediatric and adolescent population. Accurate reduction and fixation of an avulsed fragment are necessary to restore and maintain the length of the ACL and normal knee biomechanics. Several techniques are available to repair an ACL avulsion fracture. On the other hand, treatment is controversial in skeletally immature patients due to risk of physeal injury. This paper reports a case of an ACL avulsed fracture in a skeletally immature patient treated with arthroscopic all-inside suture bridge repair, in which an excellent result and firm stability were obtained without physeal injury.

Femoral avulsion fracture of posterior cruciate ligament (PCL) is rare, especially in adult. We experienced a case of femoral bony avulsion fracture of PCL. The patient was seventy one year old man with limitation of motion in the knee joint due to previous trauma and he was injured by fall down from 2 m height. We took CT scan and MRI study. We treated with arthroscopic repair technique using transfemoral two wire sutures. Second look arthroscopy was done for removal of the wires at postoperative one year.

A 4-month-old intact male Jindo dog was presented for left hindlimb lameness. On radiographs, a small mineralized piece was identified beneath the apophysis of tibia with no or minimal displacement of apophysis bilaterally. Subsequently, the cranioproximal bony aspect of the tibia changed radiolucent to radiopaque. The left side recovered after surgical management, but the right side was self-limited with conservative management. The diagnosis was partial avulsion fracture of the tibial tuberosity which has been called 'Osgood-Schlatter disease' in dogs.

Although rare, the treatment options for a medial collateral avulsion fracture during total knee arthroplasty (TKA) range from conservative management using a cast and orthosis to internal fixation using metal screws. Bioabsorbable suture anchors have been used to replace metal fixators with distinct advantages, such as biocompatibility, radiolucency, and unnecessary second removal surgery, but complications, such as osteolysis, have been reported. This paper reports a potential risk of an extensive osteolysis-related suture anchor fixation of a medial collateral ligament (MCL) avulsion fracture during TKA in conjunction with a literature review.

Purpose: We describe a new and simple technique for arthroscopic fixation of tibial intercondylar eminence avulsion fracture using bioabsorbable pins in skeletally immature patients. Operative Technique: Diagnostic knee arthroscopy is performed using anterolateral and anteromedial portals. Fracture debris and blood clot are debrided to expose the injured site well. The fragment is reduced with the probe and fixed temporarily with a 1.1-mm diameter K-wire that is inserted percutaneously from the anterosuperior aspect of the knee joint. The drill guide is introduced into the joint and the fragment is secured by bioabsorbable, poly-p-dioxanone 1.3-mm pins inserted from different angles. The pins are 40 mm in length. The knee is placed in a long leg cast in extension for 4 weeks to assure that full extension is obtained. Conclusion: Arthroscopic fixation of an tibial intercondylar eminence avulsion fracture using bioabsorbable pins is not a technically demanding, suitable method that ensures fracture healing and restores the stability of the joint.

Avulsion of the ischial tuberosity is an acute injury caused by sudden contraction of the hamstrings, typically occurs in early adolescence, whereas ischial apophysitis has a more insidious onset during times of increased activity and its diagnosis is often missed. Authors present a rare case of having neglected avulsion fracture of the the ischial tuberosity in one side and ischial apophysitis in the other side with characteristic radiological features in a 16-year-old male who was an active Tae-Kwon-Do player.

Purpose: Radiocarpal dislocation (RCD), which is caused by high-energy trauma, often involves radial styloid fractures and short radiolunate ligament (SRLL) injuries. Although SRLL injuries may occur as a simple rupture at the attachment site of radius, it may occur with a relatively large avulsed-fragment in the volar rim of the lunate facet of the radius. This study aimed to differentiate the injury type of SRLL and assess the differences in the treatment results depending on the treatment methods that have been applied in RCD with radial styloid fractures. Materials and Methods: Eighteen patients managed surgically with RCD were enrolled in this study. The patients were classified as Group 1 and Group 2 by using the Dumontier method. In this study, Group 2 was subdivided into 2A (purely ligamentous or small avulsion fracture of the volar rim of lunate facet) and 2B (large avulsed-fragment enough to internal fixation) according to the injury type of SRLL. Groups 2A and 2B were treated with direct repair and screw fixation, respectively. Pain, range of motion of the wrist joint, grip strength, and complications on final radiographs were examined. The outcomes were evaluated using patient-rated wrist evaluation (PRWE), and modified Mayo wrist score (MMWS). Results: All patients were Group 2 (six and twelve patients in 2A and 2B, respectively). The mean flexion to extension arch recovered 79%,and the mean grip strength was 72.9% of the uninjured side. Group 2A showed better recovery in extension, flexion and pronation than Group 2B, but there was no difference in radial deviation, ulnar deviation, supination, grip strength and pain. No differences in the PRWE and MMWS were observed between two groups. Complications included traumatic arthritis in seven patients and residual instability in five patients. Conclusion: When the SRLL was injured, the involvement of a large avulsion fracture on the anterior plane of the radiolunate did not affect the test results. On the other hand, it should be observed cautiously because avulsion fractures tend to disturb the joint's reduction through rotation or displacement. In addition, anatomical reduction and sturdy internal fixation are important for restoring the function of the SRLL.
