Arthroscopic microfracture with atelocollagen augmentation for osteochondral lesion of the talus: a multicenter randomized controlled trial.

Background: We aimed to evaluate whether arthroscopic microfracture with atelocollagen augmentation could improve the clinical outcomes and quality of regenerated cartilage in patients with osteochondral lesion of the talus (OLT). We hypothesized that the clinical outcomes and quality of the regenerated cartilage would be superior in patients undergoing arthroscopic microfracture with atelocollagen augmentation compared to those undergoing arthroscopic microfracture alone.

Methods: In this multicenter, randomized controlled trial, 60 patients were randomly allocated to two groups: arthroscopic microfracture with atelocollagen augmentation (group 1, n = 31) and arthroscopic microfracture alone (group 2, n = 29).

Conservative treatment of refractures after modified tension band wiring of fifth metatarsal base stress fractures in athletes.

Objective: Recurrent fifth metatarsal base stress fractures (MT5-BSF) in athletes present a challenging problem. The aim of this study was to evaluate the result of conservative treatment for the refracture of MT5-BSF after modified tension band wiring (MTBW).

Materials And Methods: The outcomes of 15 elite athletes undergoing conservative treatment for refracture of MT5-BSF after MTBW were retrospectively reviewed.

Treatment of Acute Achilles Tendon Rupture.

There is no clear consensus on the optimal treatment of acute Achilles tendon rupture. Recently, studies have demonstrated the critical role of functional rehabilitation in the treatment of ruptured Achilles tendons. Hence, conservative treatment is preferred by a growing number of surgeons seeking to treat the condition without the risk of complications from surgery.

Operative Results of Plantar Plating for Fifth Metatarsal Stress Fracture.

Background: The treatment of fifth metatarsal stress fractures can be challenging. Various operative fixation methods have been reported for fracture management. Among them, intramedullary screw fixation has become increasingly popular.

Candy Closure Technique for Chronic Open Infective Lateral Malleolus Bursitis.

The aim of this study was to report the effectiveness of the Candy closure technique as a treatment for chronic open infective lateral malleolus bursitis. From June 2014 to March 2018, we performed the Candy closure technique as a treatment for chronic open infective lateral malleolus bursitis in nine patients without secondary operation. We first performed infectious tissue debridement to control infection, and if primary closure was not possible, we performed the Candy closure technique for small wounds.

Potential of Allogeneic Adipose-Derived Stem Cell-Hydrogel Complex for Treating Diabetic Foot Ulcers.

Mesenchymal stem cells (MSCs) may hold great promise for treating diabetic wounds. However, it is difficult for a clinician to use MSCs because they have not been commercialized. Meanwhile, a new commercial drug that contains adipose-derived stem cells (ASCs) has been developed.

A chronic sinus tract infection developing after suture anchoring of the ankle: A case report.

Rationale: Suture anchors are increasingly used to fix soft tissue to bone. Favorable outcomes of the modified Brostrom operation (MBO) using suture anchors have been reported. However, to the best of our knowledge, few complications of suture anchors used in ankle surgery have been described.

Outcome of Second-Ray Pathologies Following Weil Osteotomy in Patients Treated for Hallux Valgus.

We hypothesized that the cause of second-ray pathology with hallux valgus is excessive relative length of the second metatarsal and performed Weil osteotomy to shorten it, with correction of hallux valgus. The purpose of this study is to evaluate the outcome of second-ray pathology after distal chevron osteotomy (DCO) with Weil osteotomy to correct metatarsal parabola. We performed concomitant Weil osteotomy of the second metatarsal with DCO of the first metatarsal as part of hallux valgus with second-ray pathology correction surgery in 45 feet (40 patients).

Modified Proximal Scarf Osteotomy for Hallux Valgus.

Background: We developed a modified proximal scarf osteotomy technique for moderate to severe hallux valgus in an attempt to obtain better correction of the deformity. In addition, we compared the clinical and radiographic results of this modified technique with those of the classic scarf osteotomy reported in other studies.

Methods: Between December 2004 and July 2009, 44 cases of modified proximal scarf osteotomy was performed in 35 patients with moderate hallux valgus.

Sesamoid Position in Hallux Valgus in Relation to the Coronal Rotation of the First Metatarsal.

Hallux valgus (HV) is not a simple two-dimensional deformity but is instead a three-dimensional deformity that is closely linked to sesamoid position and first metatarsal (MT) pronation. HV may or may not be accompanied by sesamoid subluxation and/or first MT head pronation. Each of these scenarios should be assessed using weighted computed tomography scan preoperatively, and the necessary corrections should be performed accordingly.

Biomechanical Comparison Study of Three Fixation Methods for Proximal Chevron Osteotomy of the First Metatarsal in Hallux Valgus.

Background: Fixation of proximal chevron metatarsal osteotomy has been accomplished using K-wires traditionally and with a locking plate recently. However, both methods have many disadvantages. Hence, we developed an intramedullary fixation technique using headless cannulated screws and conducted a biomechanical study to evaluate the superiority of the technique to K-wire and locking plate fixations.

Comprehensive Assessment of Ankle Syndesmosis Injury Using 3D Isotropic Turbo Spin-Echo Sequences: Diagnostic Performance Compared With That of Conventional and Oblique 3-T MRI.

Objective: The objective of this study is to evaluate the diagnostic performance of 3D sampling perfection with application-optimized contrasts using different flip angle evolution (SPACE) sequences in the evaluation of ankle syndesmosis injuries, compared with that of conventional orthogonal MRI and oblique proton density-weighted turbo spin-echo (TSE) sequences performed with 3-T MRI.

Materials And Methods: This retrospective study included 98 patients with suspected ankle syndesmosis injuries who underwent both MRI and surgery. Fifty patients (mean [± SD] age, 34.

Effectiveness of Headless Bioabsorbable Screws for Fixation of the Scarf Osteotomy.

Background: Scarf osteotomy has been used in hallux valgus surgery due to its large fixation surface for screws and low postoperative complications. However, screws may cause skin irritation from their head, which may require an additional surgical procedure to remove.

Methods: This study included 115 patients (106 females and 9 males, 115 feet) who underwent hallux valgus correction with a scarf osteotomy using bioabsorbable screws between September 2010 and September 2012.

Misdiagnosis of Talar Body or Neck Fractures as Ankle Sprains in Low Energy Traumas.

Background: The talus has a very complex anatomical morphology and is mainly fractured by a major force caused by a fall or a traffic accident. Therefore, a talus fracture is not common. However, many recent reports have shown that minor injuries, such as sprains and slips during sports activities, can induce a talar fracture especially in the lateral or posterior process.

Total Ankle Arthroplasty: An Imaging Overview.

With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices.

Purpose: To determine whether concomitant chronic syndesmotic injury or chronic medial ankle instability is associated with unsatisfactory outcomes in patients with chronic lateral ankle instability (CAI).

Methods: We conducted a retrospective review of prospectively collected data from 276 male military patients with CAI who had undergone a modified Broström procedure between May 2007 and March 2010 and had been followed up for a mean of 26.7 months (range, 22 to 41 months).

A Case of Glomangiomatosis of the Ankle and Foot: Ultrasonographic Appearance Correlated With the Magnetic Resonance Imaging Findings.

Glomangiomatosis, a rare category of glomus tumors, comprises 2% to 3% of glomus tumors in adults. We report a case of glomangiomatosis in a 48-year-old man who underwent multiple excisions of recurrent soft tissue masses in the ankle and foot. Ultrasonography revealed multiple nodular soft tissue tumors and dilated vascular channels with increased blood flow, suggesting the presence of vascular tumors.

A New Measure of Tibial Sesamoid Position in Hallux Valgus in Relation to the Coronal Rotation of the First Metatarsal in CT Scans.

Background: We aimed to find a new radiographic measurement for evaluating first metatarsal pronation and sesamoid position in hallux valgus (HV) deformity.

Methods: Data from a clinical study of 19 control patients (19 feet) with no HV deformity were compared with preoperative data of 138 patients (166 feet) with HV deformities. Using a weightbearing plain radiograph in anteroposterior (AP) view, the intermetatarsal angles (IMAs) and the hallux valgus angles (HVAs) of the control and study groups were measured.

Paratrooper's ankle fracture: posterior malleolar fracture.

Background: We assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes.

Methods: Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications.

Osteoarthritis of the second metatarsophalangeal joint associated with hallux valgus deformity.

Background: Hallux valgus is speculated to increase the load on the second metatarsophalangeal (MTP) joint, possibly inducing degenerative osteoarthritis. In addition, the severity of arthritis may be correlated with the severity of hallux valgus. This study evaluated the association of arthritis of the second MTP joint in hallux valgus patients and the relationship between arthritis of the second MTP joint and hallux valgus deformity.

Deltoid ligament in acute ankle injury: MR imaging analysis.

Objective: To identify the pattern of deltoid ligament injury after acute ankle injury and the relationship between ankle fracture and deltoid ligament tear by magnetic resonance imaging (MRI).

Materials And Methods: Thirty-six patients (32 male, and 4 female; mean age, 29.8 years) with acute deltoid ligament injury who had undergone MRI participated in this study.

Factors associated with recurrent fifth metatarsal stress fracture.

Background: Many surgeons agree that fifth metatarsal stress fractures have a tendency toward delayed union, nonunion, and possibly refracture. Difficulty healing seems to be correlated with fracture classification. However, refracture sometimes occurs after low-grade fracture, even long after apparent resolution.
