Pseudoaneurysm is extremely rare complication after ankle arthroscopy with standard anteromedial and anterolateral portals. We report a case of a pseudoaneurysm of the anterior tibial artery detected at 3 months after ankle arthroscopy in a 16-year-old male. He had sustained painful swelling of his right ankle after the arthroscopic surgery, and referred to our hospital with an MRI checked postoperatively. We failed to make the diagnosis of pseudoaneurysm with the postoperative MRI, thus the patient underwent another arthroscopy which revealed massive hemarthrosis within the joint. The diagnosis was confirmed with an angiography, and the vascular lesion was ligated.

Microfracture as a reparative strategy is the treatment of choice for an osteochondral lesion of talus. Although the results of microfracture are generally excellent, at least 30% of patients who received microfracture have acute or chronic ankle pain with several or unknown causes. The most important factor for unsatisfactory outcome after microfracture is the size of the lesion. For failed osteochondral lesion of talus, the second options are autologous osteochondral graft, autologous chondrocyte implantation, or re-microfracture. In this article, we present the autologous chondrocyte implantation as a second procedure for failed microfracture and compare its clinical outcome with other methods based on a literature review.

A modified $Brostr{\ddot{o}}m$ procedure has been widely accepted as a treatment of choice for patients with chronic lateral ankle instability. The procedure is highly reliable and provides successful outcomes in approximately 90% of cases. Severe degree of instability, absence or poor quality of the ligamentous remnant, obesity, and generalized joint hypermobility have been regarded as poor prognostic factors related to the modified $Brostr{\ddot{o}}m$ procedure. However, these perceptions are based on a low level of evidence studies or expert opinions. Therefore, the aim of this article was to search for evidences regarding the poor prognostic factors of the modified $Brostr{\ddot{o}}m$ procedure.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.

Recurrence is a common complication following hallux valgus surgery. The postoperative recurrence rates have been reported to be between 2.7% and 16%. Reoperation is considered only for the recurrent deformities with intractable pain. The success of reoperation depends on identifying and addressing the cause of the recurrence appropriately. The surgical principle of reoperation for a recurrent hallux valgus is similar to that of the primary surgery, but arthrodesis and proximal metatarsal osteotomies with greater correcting power are adopted more frequently.

Symmetrical Digital Gangrene (SDG) is characterized by the sudden onset of peripheral, symmetrical gangrene in the absence of any major vascular occlusive disease. Catecholamine inotropes are frequently used for the treatment of septic shock combined with an unstable hemodynamic state, and their usage can rarely induce SDG. There is no standard treatment for the SDG. Early recognition and prompt management of sepsis and expeditious process of weaning off of the inotropes are necessary to prevent progression of SDG. To the best of our knowledge, this is the first report in Korea regarding the treatment of SDG induced by catecholamine inotropes.

Symptomatic neuromas after amputation can be troublesome to treat and make it difficult to properly fit a brace. Surgical management is required when conservative management such as prosthetic socket modification or local injections fail. However, small cutaneous nerves adhere to adjacent soft tissue and they are difficult to locate. The authors suggest that ultrasonography guided tattoo localization using a charcoal suspension is useful to find a visually indistinguishable neuroma.

Motion of the metatarsophalangeal joints is essential for the normal gait. Therefore it is important to recover the motion of normal joint in the treatment of stiffness of the metatarsophalangeal joints. However, there have been no report about the treatment of stiffness of the four lateral lesser metatarsophalangeal joints yet. We report an experience that good clinical and radiographic results were obtained after resection arthroplasty for the post-traumatic stiffness of the four lateral lesser metatarsophalangeal joints.

Patients with chronic lateral ankle instability often experience a range of associated injuries. The well-known comorbidities include intra-articular pathologies (osteochondral lesion, soft tissue or bony impingement, and loose body), peroneal tendon pathologies, neural injuries, and other extra-articular pathologies. Surgeons should have a high index of suspicion for these associated pathologies before operative intervention, correlate the clinical findings, and plan the treatment. Despite the restoration of ankle stability following ligament repair or reconstruction surgery, a high prevalence (13%~35%) of postoperative residual pain has been reported. This pain can negatively affect the clinical outcomes and patient satisfaction. This study examined the causes of persistent pain after surgical treatments for chronic ankle instability.

As a result of the increased participation in recreational and competitive sports activity, the incidence of chronic lateral instability has risen. Because chronic ankle instability can cause significant comorbidity and increase the social cost, the interest in this issue is growing. Although there are well-documented and effective surgical treatments for managing this condition, conservative treatments are a viable first option in selected patients. Through conservative treatment, surgical treatments can be reduced or delayed without necessarily affecting the overall outcome, but the failure of conservative treatment results in the need for surgical treatment to reduce the long term complications. Appropriate postoperative rehabilitation is essential for adequate functional recovery, even when surgical treatment is required.
