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.

Occurrence of pseudoaneurysm in the foot and ankle is rare, and is usually caused by traumatic injury or by iatrogenic intervention. Iatrogenic pseudoaneurysms in the foot and ankle have been observed after rearfoot and ankle fusions, ankle arthroscopy, endoscopic and open plantar fasciotomy, tibial osteotomy with limb lengthening, midfoot amputation, and Lapidus procedure. We report on a patient who developed a pseudoaneurysm of the dorsal metatarsal artery following correction of hallux valgus. The patient underwent proximal chevron osteotomy and Akin phalangeal osteotomy. The feeding artery was ligated and the pseudoaneurysm was excised.

Acute ankle sprain is the most common injury in the lower extremities, and approximately 10% to 40% of acute lateral ankle ligament injury causes chronic pain or instability. For chronic symptoms lasting after an acute sprain, the possibility of joint damage, such as bony structures, ligaments, cartilage, and nerves around the ankle joint, should be considered. Patients with chronic lateral ankle instability usually complain of repeated sprains or giving way sensations. There has been steady progress in the treatment options until recently, however new treatments are still being attempted. This paper describes the causes, diagnosis, and recent trends in the conservative and operative treatment of chronic lateral ankle instability.

Impingement syndrome of the ankle is defined as painful mechanical limitation of full ankle movement secondary to osseous and/or soft tissue abnormality. These conditions occur more commonly in active people and athletes probably because recurrent subclinical injury is an important factor in development of the syndrome. Impingement syndromes of the ankle are categorized according to their anatomical site around the ankle joint. Anterolateral, anterior and posterior impingement has been extensively described in the orthopaedic literature. The purpose of this article is to review the clinical feature and management of anterior impingement syndrome of the ankle.

Total ankle replacement has been performed for treatment of end stage arthritis of the ankle, hopefully being an alternative to ankle arthrodesis. However, due to its high failure rates, earlier versions of ankle replacements were not regarded as successful procedures. The latest design has shown increasingly positive results. Total joint replacement of the ankle itself is still regarded as a demanding procedure and much more challenging than that of the hip and knee in many aspects. Several studies, however, have pointed out that it is becoming the viable, accepted alternative for arthrodesis with advanced implants, appropriate patient selection, and proper training experience of procedures. Compared with arthrodesis, it shows equal or better outcomes in pain relief, range of motion, and patient's satisfaction. We are attempting to review its biomechanical characteristics, implant design, indications, complications, clinical outcomes, and survival rate.

Major technologic advances in fiberoptic light transmission, video cameras, and instrumentation have allowed great advances in small-joint arthroscopy. Arthroscopy in particular is now well established procedure for accurate diagnosis and operative management of certain ankle disorders. The small size of the ankle and significant periarticular soft tissue structures make placement and advancement of the arthroscope and instrumentation more difficult than in larger joints. Successful arthroscopy of the ankle requires knowledge of the regional anatomy and a familiarity with the available arthroscopic portals. This review article is going to describe the gross and arthroscopic anatomy of the ankle as it relates to current arthroscopic techniques. Particular emphasis is placed on the anatomic relations of the important osseous and soft tissue structures for a safe, reproducible approach to arthroscopic treatment of ankle pathology. Also, current arthroscopic equipment and instruments are included.

Ankle arthrodesis has been used as standard treatment of ankle arthritis unresponsive to conservative treatment. Transfibular approach was used for ankles with severe deformities and minimally invasive arthroscopic ankle arthrodesis was used for patients with mild deformities. Anterior approach may be used when lateral approach couldn't be performed. Tibiotalocalcaneal arthrodesis is standard treatment for coexisting ankle and subtalar arthritis, and modified Blair arthrodesis can be used if the talus body resection is necessary in severe talar necrosis. In serious infection of ankle arthritis, arthrodesis can be performed as staged operation. In cases with low bone density and severe deformities, Charcot arthropathy should be considered.

In this study, ground reaction force(GRF), absolute symmetry index(ASI) and coefficient of variation(CV) of fixed, single-axis and multi-axis prosthetic ankle assemblies were investigated to show the biomechanical evaluation for above knee amputees. In the experiments, 37 normal male volunteers, two male and two female AK amputees were tested with fixed, single-axis and multi-axis prosthetic ankle assembly. A gait analysis was carried out to derive the ratio of GRF to weight as the percentage of total stance phase for ten points. The results showed that fixed-axis ankle was superior to the other two ankle assemblies for the characteristic of forwarding and breaking forces. Multi-axis ankle was relatively superior to the other two ankle assemblies for gait balancing and movement of the center for mass. single-axis ankle was relatively superior to the other two ankle assemblies for CV and ASI of GRF.

Chronic lateral ankle instability occurs in 10% to 20% of individuals after acute ankle sprain. The management of chronic lateral ankle instability is traditionally conservative treatment in the acute phase. On the other hand, surgical intervention is considered if conservative treatment fails and the symptoms are ongoing. This review focuses on the surgical approaches to treatment of chronic lateral ankle instability, including $Brostr{\ddot{o}}m$ surgical techniques, with a review of the traditional procedure and newer techniques.

It has been reported that gastrocnemius tightness and posterior talar glide are crucial factors influencing ankle dorsiflexion. However, the relationship of ankle dorsiflexion and these factors is not identified in previous studies. The purpose of this study was to identify the relationship of ankle dorsiflexion passive range of motion and gastrocnemius tightness and posterior talar glide. Twenty-five male subjects participated in this study. Bilateral weight-bearing ankle dorsiflexion passive range of motion and amount posterior talar glide of participants were measured using an inclinometer. Change in myotendinous junction of medial gastrocnemius was measured using ultrasonography to identify gastrocnemius tightness. Pearson product moment correlations were performed to examine correlations between ankle dorsiflexion passive range of motion and gastrocnemius tightness and posterior talar glide. Present findings revealed significant correlation between ankle dorsiflexion passive range of motion and gastrocnemius tightness (p=0.017, r=0.336). Also, ankle dorsiflexion passive range of motion was correlated with posterior talar glide (p=0.001, r=0.470). The present findings provide experimental evidence for factors influencing weight-bearing ankle dorsiflexion.
