Severe ankle sprain secondarily leads to chronic lateral ankle instability in 20-30%. Many surgical procedures have been presented for reconstruction of the lateral ankle instability, but controversy still remains for the ideal surgical option. Br$\ddot{o}$strom procedure or its modifications have been widely used but they have some limitations for the instabilities for the over-weight, physically high demanding patients and especially for significantly deficient or attenuated ligaments. Moreover the tenodesis procedures using peroneus brevis tendon are non-anatomical and sacrifice important lateral stabilizing tendon. Therefore recently, many reconstructive procedures for lateral ankle instability utilizing free allograft or autograft tendon have been introduced to anatomically stabilize the lateral ligaments to various degrees.

Traumatic dislocation of the peroneal tendon is an infrequent injury. This injury is caused by forceful dorsiflexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior peroneal retinaculum and allows the tendons to snap anteriorly. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by bone block surgery using autograft of lateral fibula and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

This is a case of the core reamer breakage during anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft. A 19-year-old man with acute anterior cruciate ligament rupture had reconstruction surgery. During tunneling in the proximal tibia, the core reamer have been cracked open and broken. Rest of the procedure was performed routinely except the tibial sided fixation of bone block which was performed with larger interference screw than usual. The patient followed the accelerated rehabilitation program. The result was satisfactory at 2 years after surgery.

Bone-grafting procedures are common in orthopedic trauma surgeries. There are only few reports on the morbidity after proximal tibia harvesting. Here, we report an experience of complication after proximal tibia harvesting while treating subtrochanteric femoral osteomyelitis.

The pretibial cyst is a very rare complication after anterior cruciate ligament (ACL) reconstruction. It occurs whatever kind of graft choice or kind of graft fixation method at tibial side. It have been known such as graft necrosis at tibial side, extra-articular leakage of joint fluid through tibial tunnel, foreign body reaction due to breakdown of the bioabsorbable screw and incomplete incorporation of graft to bony tunnel as the cause of pretibial cyst. We experienced one case of pretibial cyst which had undergone ACL reconstruction with autogenous hamstring graft fixed with biodegradable interference screw. We report a rare case of pretibial cyst with literature review.

Cranioplasty is performed using autograft and allograft materials on patients to whom craniectomy was applied previously due to the facts that, this region is open to trauma and the scalp makes irritation and pressure onto the brain paranchyma causing brain atrophy and convulsions. Dramatical improvement of neurological deficits, control of convulsions and partial prevention of cerebral atrophy are achieved after these operations. One of the most important complications of cranioplasty is late infection. Here, we report a 43-year-old male patient admitted with the history of purulant discharge from the right temporal incission site for one year to whom cranioplasty had been performed with allograft material 20 days after craniectomy which had been performed in 1989. Allograft cranioplasty material was removed and cranioplasty was performed using new allograft material with the diagnosis of late cranioplasty infection.

Persistent instability following an acute lateral ankle sprain eventually require ligamentous reconstruction in some cases. Over 50 surgical procedures have been described to reestablish lateral ankle stability varying from direct in situ repair of the anterior talofibular ligament and the calcaneofibular ligament to augmented reconstructions with either autograft or allograft tissue. The author describes the rationale and the technique of anatomic ankle ligament reconstruction with the 4th extensor digitorum longus tendon.

Osteochondral lesions of the talus are isolated cartilage and/or bone lesions that are known cause of chronic ankle pain. They can occur as the result of a single acute ankle injury or from repetitive loading of the talus. Technical development in radiologic imaging and ankle arthroscopy have improved diagnostic capabilities for detecting osteochondral lesions. Characteristics which are important in assessing an osteochondral lesions include: the size, the type (chondral, subchondral, cystic), the stability, the displacement, the location, and the containment of lesion. Nonoperative treatment involving period of casting and non-weight-bearing is recommended for acute, non-displaced osteochondral lesions in select pediatric and adolescent patients. Operative treatment is recommended for unstable lesions or failed conservative management. Marrow stimulation techniques (abrasion chondroplasty, multiple drilling, microfracture), osteochondral autograft or allograft, autologous chondrocyte implantation, are frequently employed. The purpose of this article is to review the historical background, etiology, classification systems, diagnostic strategies, and to describe a systematic approach to management of osteochondral lesions of the talus.
