Background Anatomically surgical reduction of ankle fractures does not always result in a clinically favorable outcome. Arthroscopic examination combined with treatment of intra-articular lesion may related to clinical outcomes Objectives The purpose of the present study was to review initial and second look arthroscopic finding of acute ankle fracture and to evaluate clinical outcomes. Results Lauge-Hansen classification system of ankle fractures included supination-external rotation type (n = 24), supination-adduction type (n = 3), pronation-external rotation type (n = 7), and pronation-abduction type (n = 6), total 40 ankles. Osteochondral lesions were found in 25 ankles (62%) with an initial arthroscopic finding of acute ankle fracture. Newly discovered chondral lesions in secondary arthroscopy were found in 17 cases. According to the Ferkel and Cheng staging at secondary arthroscopy, 4 of 25 ankles with osteochondral lesions of the talus were deteriorating (more than stage D). In terms of ICRS overall repair grades, 5 ankles (20%) were abnormal (grade III). Diffuse synovitis and arthrofibrosis were found in 12 and 7 ankles, respectively, in secondary arthroscopy, and correlations were found between AOFAS scores, VAS and intra-articular lesions. Conclusion Second-look arthroscopic examination combined with treatment of intra-articular lesion such as arthrofibrosis and osteochondral lesion arising from ankle fracture surgery may consider to improve clinical outcomes.

Deltoid ligament repair can be challenging, and implementation of an arthroscopic method can be useful in terms of minimizing morbidity associated with open dissection, as long as the repair is effective and durable. In this brief report, we describe a method of arthroscopic deltoid ligament repair that we have found to be useful.

Background: Morton's neuroma is a common cause of metatarsalgia and many treatments had been described in literature. However, there have been only a few reports that treat the neuroma with an osteotomy on the proximal, not distal portion of the metatarsal bone using a plate. This study describes the clinical outcome of sliding osteotomy on the proximal metatarsal bone for the treatment of Morton's neuroma. Materials and Methods: Sixty five consecutive patients (85 feet) who underwent surgery for Morton's neuroma between November 2010 and February 2013 were identified from hospital records to include in this retrospective study. Average followup period was 37.3 months (range 24–51 months). Mean patient age at surgery was 50.2 years (range 23–75 years). Metatarsal sliding osteotomies were only performed on the third metatarsal bone. Clinical evaluations with the American Orthopaedic Foot and Ankle Society Lesser Metatarsophalangeal Interphalangeal Scale (AOFAS LMIS) and Foot Function Index (FFI) were performed. The length of the lesser toe was measured for radiologic evaluation. Results: Postoperatively, AOFAS LMIS and FFI were improved from 52.1 (range 45–60) and 62.4 (range 54–73) to 74.2 (range 68–86) and 31.3 (range 26–37). At the last followup, preoperative pain was dissolved in 79 feet (93% of overall 85 feet). A shortened 3.2 mm (±1.1) metatarsal bone following osteotomy was radiographically measured. There were six cases of complications (soft tissue infection, early numbness, delayed union, limitation of dorsiflexion and metal failure, etc.). Conclusions: This proximal metatarsal sliding osteotomy can be a relatively effective operative method in relieving pain from Morton's neuroma.

The present study compared the quality of reduction and the clinical assessment between screw fixation and suture-button fixation with an ankle fracture accompanied by syndesmosis injury. We studied the clinical and radiologic findings 1 year postoperatively through retrospective examination of 24 patients who had undergone screw fixation from January 2011 to December 2012 and prospective examination of 20 patients who had undergone suture button fixation from January 2013 to May 2014. Regarding the tibiofibular clear space, tibiofibular overlap, and medial clear space, the screw fixation group had improvement from a preoperative mean of 6.97 (range 2.79 to 15.81) mm, 4.43 (range 0 to 7.87) mm, 7.90 (range 4.24 to 19.50) mm to a postoperative mean of 4.95 (range 2.72 to 9.08) mm, 6.29 (range 0 to 10.37) mm, and 4.32 (range 1.98 to 6.57) mm, respectively. The corresponding improvement for the suture-button fixation group was from a preoperative mean of 6.65 (range 3.94 to 13.73) mm, 5.39 (range 0 to 9.44) mm, 7.27 (range 4.04 to 16.00) mm to a postoperative mean of 5.15 (range 2.93 to 7.30) mm, 7.21 (range 2.15 to 10.30) mm, and 4.25 (range 2.97 to 5.71) mm. No statistically significant difference was found between the 2 techniques. Both suture-button and metal screw fixation are effective treatment methods for an ankle fracture accompanied by syndesmosis injury. However, a long-term and prospective analysis is needed.

Background To compare the effectiveness of intraoperative three-dimensional (3D) image and conventional two-dimensional (2D) fluoroscopic images, which are used in the treatment of acute calcaneal fractures. Methods We retrospectively analyzed 40 patients who suffered calcaneal fracture and underwent surgery at Inje University Busan Paik Hospital. The patients were divided into two groups. Only 2D fluoroscopy was used to evaluate 20 patients of group 1. On the other hand, 3D fluoroscopy was performed on the remaining 20 patients of group 2; 3D fluoroscopy was performed on these patients after they were extensively evaluated by 2D fluoroscopy during surgery. We reviewed the radiographic and clinical outcomes of these patients, whose average follow-up period was 42.6 months. Results In group 2, 3D fluoroscopy detected four cases (20%) of articular incongruence and screw misplacement. All these complicated cases were corrected during surgery. At the final follow-up session, the mean American Orthopedic Foot and Ankle Society (AOFAS) hind foot score was 78.3 (range, 65 to 95) in group 1 and 82.3 (range, 68 to 95) in group 2. Conclusions Intraoperative 3D imaging of calcaneal fractures is considered to be useful in evaluating the congruence of joints and the placement of implants.

Purpose To compare the clinical results of single-bundle anterior cruciate ligament (ACL) reconstruction using the conventional transtibial technique and the anatomical outside-in technique for femoral tunneling. Materials and Methods From 2007 to 2011, 89 patients who received ACL reconstruction were followed for ≥1 year were enrolled in the study. The conventional transtibial technique was used in 41 patients and the outside-in technique, in 48 patients. Femoral tunnel angle measurement and three-dimensional computed tomography (3D CT) were used for radiologic assessment of the location of femoral tunnel and Lysholm score and other tests were used for clinical assessment. Results Both techniques did not reveal statistical differences in the clinical assessment. However, in International Knee Documentation Committee subjective knee evaluation, the sum of two questionnaire items regarding instability showed a statistically significant difference (p=0.01). In the pivot shift test, the anatomical outside-in technique showed outstanding rotational stability over the transtibial technique (p=0.04). The mean femoral tunnel inclination in coronal plane were 69.2° and 30.3°, respectively, for both techniques, and 21.6° and 50.8°, respectively in sagittal plane, showing statistically significant differences on simple radiography (p=0.04, 0.05). A 3D CT was performed in 17 patients with the conventional transtibial technique and 25 patients with the outside-in technique. Coefficients of variation were 0.33 and 0.13, respectively, from dorsal border of the condyle and 0.67 and 0.24, respectively, from the roof of intercondylar notch. Conclusions Femoral tunnels created with the outside-in technique have superior knee joint rotational stability compare to the transtibial technique. Therefore, the outside-in technique could be considered as a valuable technique in single-bundle ACL reconstruction.

Category: Ankle Introduction/Purpose: This retrospective study was performed to evaluate the clinical outcomes of internal brace technique using suture tape for chronic ankle instability. Methods: twenty-three patients were followed for more than 2 years after suture tape augmentation for lateral ankle instability. Twenty five patients were followed for more than 2 years after modified Brostrom procedure. The clinical results after using two techniques were evaluated and compared using Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot and Ankle Society (AOFAS) score, Olarud and Molander score, Hamilton score and Visual Analogue Scale (VAS). Anterior talar translation and talar tilt angle were obtained from stress radiographs to evaluate the mechanical ankle stability. Results: There was no significant difference in VAS at final follow-up (P < .325). There was no significant difference in FAOS at final follow-up (P < .242). There was no significant difference in AOFAS score at final follow-up (P < .418). There was no significant difference in Olarud and Molander score at final follow-up (P < .244). According to the Hamilton score, 14 cases (93%) in internal brace group and 23 cases (92%) achieved satisfactory functional results. Talar tilt angle and anterior talar translation had improved to an average of 2.2 degrees and 4.4 mm in internal brace group and 2.7 degrees and 5.4 mm in modified Brostrom group, respectively, at final follow-up, and there was no significant difference (P < .128, < .226, respectively). There were no complications such as skin irritation and wound infection. Conclusion: Suture tape augmentation has shown the potential for stabilizing the lateral ankle ligmament complex as an alternative to direct repair. Functional, objective, and subjective outcomes were excellent in all cases and no complications were seen postoperatively. To confirm the above further, it is appropriate to conduct a larger study.

Purpose: Not much is known about the obvious relationship between posteroinferior rotator cuff tear and biceps lesion. The purpose of this study is to analyze the effect of posteroinferior rotator cuff tear on a biceps lesions by comparing the rotator cuff tear and biceps lesions with the number of cuff tears and the degree of degeneration of the rotator cuff. Materials and Methods: 65 patients who underwent surgery for a posteroinferior rotator cuff tear from 2002 to 2009 were included as subjects. The study determined the factors (the number of cuff tears and the degree of degeneration as assessed by MRI) that affected biceps lesions and the kinematic stability of the rotator cuff. Results: Biceps lesion was noted 11 patients among the 51 patients with supraspinatus tendon tears and in 8 patients among the 14 patients with supraspinatus, infraspinatus or teres minor tendon tears, and there was a statistically significant difference between those two groups (p

The aim of the present study was to evaluate the radiologic factors related to ankle pain before and after total knee arthroplasty (TKA) among patients with a varus osteoarthritic knee. Fifty-five patients (65 ankles) with a varus osteoarthritic knee who had undergone TKA and were followed up for >24 months were enrolled. For clinical assessment, the visual analog scale for pain and the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale were used. For radiologic assessment, the mechanical axis deviation angle, talar tilt, tibial anterior surface angle, distal medial clear space, medial tibiotalar joint space, frontal tibial ground angle, and hindfoot alignment view angle were measured. The patients with ankle pain before TKA (11 ankles) had a larger hindfoot alignment view angle (9.2° ± 2.6°) than that of patients without ankle pain before TKA (54 ankles; 5.5° ± 4.8°; p = .007). The patients with newly developed ankle pain or experienced an aggravation of existing pain after TKA (8 ankles) had a significantly larger degree of residual varus (5.1° ± 2.1°) than did the patients without ankle pain before and after TKA or those with ankle pain before surgery. However, the severity of the pain was not different during the follow-up period (52 ankles; 1.6° ± 2.5°; p = .001). The results of the present study showed that residual varus deformity was associated with ankle pain after TKA. Surgeons should perform evaluations of the ankles of patients who complain of pain before and after TKA and should give careful attention to the correction of alignment during TKA.

Chronic recurrent multifocal osteomyelitis (CRMO) is a non-infectious inflammatory bone disease that occurs mainly in children and adolescents. The clinical presentation shows imprecise bone pain, while radiologic findings and histologic exam are similar to those of infectious osteomyelitis. It is a rare disease, which is difficult to distinguish from other diseases, therefore it could be misdiagnosed. We report on a case of CRMO on the distal tibia and fibula in an 11-year-old boy.
