Purpose: The purpose of this study is to compare the clinical results between two different methods of hindfoot endoscopy to treat posterior ankle impingement syndrome. Materials and Methods: Between January 2008 and January 2014, 52 patients who underwent hindfoot endoscopy were retrospectively reviewed. Two methods of hindfoot endoscopy were used; Group A was treated according to van Dijk and colleagues' standard twoportal method, and group B was treated via the modified version of the above, using a protection cannula. For clinical comparison, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, time required to return to activity, and the presence of complications were used. Results: There was no statistically significant difference in the AOFAS scores at the final follow-up, and there was also no statistically significant difference in the times for the scores to return to the preoperative level. There were no permanent neurovascular injuries and wound problems in either group. Conclusion: Use of protection cannula may provide additional safety during hindfoot endoscopy. We could not prove whether protection cannula can provide superior safety for possible neurovascular injury. Considering the possible safety and risk of using additional instrument, the use of this method may be optional.

Purpose : The purpose of this study was to investigate the change of the peak plantar pressure distribution under the foot areas and the range of motion (ROM) of ankle joint according to gradients in treadmill gait. Method : Thirty normal subjects (15 male and 15 female) walked on treadmill at three gradient conditions ($0^{\circ}$, $10^{\circ}$, and $15^{\circ}$) in normal speed. The ankle ROM was measured using the CMS70P that is three dimensional analyzer for excursion of ankle ROM, plantar flexion, and dorsi flexion. The peak plantar pressure distribution under the hallux, 1st metatarsal head (MTH) and heel was measured using the F -Scan system with an in-shoe sensor. Data was collected from 9 steps of left sife foot in at each gradient condition while all subjects walked. Result : As the treadmill gradient increased, the excursion of ankle joint was significantly increased (p<.05). Also, plantar flexion and dorsi flexion was significantly increased according to treadmill gradients (p<.05). The peak plantar pressure under the 1st MTH was significantly increased (p<.05) and the peak plantar pressure under the heel was significantly decreased (p<.05) as the treadmill gradient increased. No significant different in the peak plantar pressure under the hallux was observed. Conclusion : This study suggests that physical therapy for patients who have limited ankle ROM should be considered sufficient range of motion for functional ambulation. And individuals that have painful forefoot syndromes, including metatarsalgia, hallux valgus, and plantar ulceration should be careful in walking to uphill, as there is high plantar pressure under the forefoot.

Purpose: The purpose of this study is to establish guidelines for ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure with regard to healing of diabetic foot amputation wound. Material and Methods: We designed a retrospective study that included patients with diabetic foot ulcer. From 2008 to 2011, 46 patients who had suffered from amputation of a foot due to diabetic foot ulcer were included in this study. We divided them into amputation-success group and amputation-revision group, and compared their ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure between two groups. Amputation-revision group is that first forefoot amputation is failed to heal successfully and need to have another proximal amputation. Results: Toe pressure was 78 mmHg (54~107) in the amputation success group, 0 mmHg (0~43) in the amputation revision group (p=0.000). Ankle-brachial index was 1.1650(1.0475~1.1975) in the amputation success group, 0.92(0.5275~1.0750) in the amputation revision group (p=0.05), and toe-brachial index was 0.6100(0.4050~0.7575) in the amputation success group, 0.00(0.00~0.4150) in the amputation revision group (p=0.04), respectively. Conclusion: ABI, TBI, toe pressure of amputation success group were significantly higher than those of amputation revision group.

Purpose: The aim of this study was to evaluate biological ligament healing quantitatively after suture-tape augmentation for chronic lateral ankle instability. Materials and Methods: Thirty-two patients underwent magnetic resonance imaging (MRI) at a minimum of 2 years after lateral ligament augmentation using suture-tape. Signal/noise ratios (SNRs) and widths of anterior talofibular ligaments (ATFLs) were measured on preoperative and postoperative MRI by three researchers. ATFL biological healing degrees were analyzed using changes in SNRs and widths of ATFLs and by comparing these metrics with those of normal contralateral ankles. Clinical evaluations were performed using foot and ankle outcome scores (FAOSs), Foot and Ankle Ability Measure (FAAM) scores, and ankle stress radiographs. Results: Mean FAOS and FAAM scores improved significantly from 62.4 to 93.6 and 58.3 to 92.3, respectively, at final follow-up (p<0.001). Mean SNRs and ATFL widths improved insignificantly from 8.49 to 8.21 and 2.07 to 2.15 mm, respectively, at final follow-up (p=0.424, p=0.718). Significant differences in mean SNRs and ATFL widths were found between ipsilateral and contralateral sides (p<0.001, p=0.002). Spearman's correlation analysis revealed no significant association between clinical outcomes and degrees of biological healing of ATFLs based on MRI findings. Conclusion: Despite improvements in clinical outcome measures, the effects of suture-tape augmentation for chronic lateral ankle instability on biological ligament healing were insignificant. In addition, no significant correlation was found between clinical outcomes and degrees of biological healing of ATFLs.

Objective: The aim of this study was to analyze body stability Joint coordination pattern though as bending stiffness of shoes during stance phase of running. Method: 47 male subjects (Age: 26.33 ± 2.11 years, Height: 177.32 ± 4.31 cm, Weight: 65.8 ± 3.87 kg) participated in this study. All subjects tested wearing the same type of running shoes by classifying bending stiffness (A shoes: 3.2~4.1 N, B shoes: 9.25~10.53 N, C shoes: 20.22~21.59 N). They ran 10 m at 3.3 m/s (SD ±3%) speed, and the speed was monitored by installing a speedometer at 3 m intervals between force plate, and the measured data were analyzed five times. During running, ankle joint, MTP joint, coupling angle, inclination angle (anterior-posterior, medial-lateral) was collected and analyzed. Vector coding methods were used to calculate vector angle of 2 joint couples during running: MTP-Ankle joint frontal plane. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was Bonferroni. Results: Results indicated that there was an interaction between three shoes and phases for MTP (Metatarsalphalangeal) joint angle (p = .045), the phases in the three shoes showed difference with heel strike~impact peak (p1) (p = .000), impact peak~active peak (p2) (p = .002), from active peak to half the distance to take-off until take-off (p4) (p = .032) except for active peak~from active peak to half the distance to take-off (p3) (p = .155). ML IA (medial-lateral inclination angle) for C shoes was increased than other shoes. The coupling angle of ankle angle and MTP joint showed that there was significantly difference of p2 (p = .005), p4 (p = .045), and the characteristics of C shoes were that single-joint pattern (ankle-phase, MTP-phase) was shown in each phase. Conclusion: In conclusion, by wearing high bending stiffness shoes, their body instability was increased during running.

Purpose: This study aimed to evaluate the effectiveness of deltoid ligament repair on syndesmotic stabilization in patients with acute ankle fractures with ruptured deltoid and syndesmotic ligaments. Materials and Methods: The medical records of 41 patients (41 ankles) who underwent surgery for Weber type B ankle fracture with ruptured deltoid and syndesmotic ligaments were retrospectively analyzed. The mean follow-up duration was 36 months (range 18~65 months). Patients were divided into two groups: those that underwent deltoid ligament repair (the deltoid group) and those who did not (the non-deltoid group). Both groups were also divided into two subgroups, namely, the D1/S1 group, which underwent syndesmotic screw fixation, or the D2/S2 group, which did not. Medial clear space (MCS), tibiofibular clear space (TFCS), anterior fibular line (AFL) ratio, and posterior fibular line (PFL) distance were measured, and visual analog scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS), and Foot Function Index (FFI) scores were evaluated. Results: TFCS changed significantly after surgery in the D2 and S1 groups (p=0.01, p=0.03, respectively). Subgroup MCSs, TFCSs, and AFL ratios were not significantly altered by surgery in the four subgroups (p=0.82, p=0.45, p=0.25, respectively). However, postoperative PFL distances were significantly different in the D2 and S1 groups and the S1 and S2 groups (p=0.02, p=0.02, respectively). Mean TFCS decreased significantly after surgery in the D2 and S1 groups. The postoperative VAS, AOFAS scores, and FFI were not significantly different between the subgroups (p=0.44, p=0.40, and p=0.46, respectively). Conclusion: Deltoid ligament repair seemed to restore ankle stability without addressing syndesmosis in Weber type B ankle fractures with rupture of deltoid and syndesmotic ligaments.

Purpose: Tumors of the foot and ankle account for approximately 3%~5% of all musculoskeletal tumors, and accurate diagnosis is often delayed due to their rare prevalence. Therefore, the authors aimed to analyze the incidence, treatment methods, and prognostic factors of foot and ankle tumors treated at the authors' hospital. Materials and Methods: A retrospective single-center study examined 342 patients treated for foot and ankle tumors at the authors' hospital from January 2011 to February 2022. Data were collected from the electronic medical records (EMR) and picture archiving and communication systems (PACS). The information analyzed included gender, age, follow-up period, diagnosis, tumor occurrence and recurrence, treatment, and clinical outcomes. Results: Most cases (93.3%) were benign, but 6.7% were malignant. The main treatment for malignant tumors was surgical resection (91.3%). Approximately 53.1% of benign tumors and 91.3% of malignant tumors were treated with surgery, and two of the malignant tumors that did not undergo surgery had metastatic cancer. After surgery, 8.2% of benign lesions and 19.0% of malignant lesions recurred, and 9.5% of the patients with malignant tumors died after surgery. Conclusion: Most foot and ankle tumors are benign tumors, and the prognosis is not poor if treated properly, but most malignant tumors often require amputation. In some cases, however, amputation can be avoided with a combination of chemotherapy and radiation therapy.

Background: Ankle sprains are a common clinical ankle disorder and alternations in tibiofibular joint biomechanics along with the talus are thought to contribute to its occurrence. During ankle joint dorsi flexion, proper movement requires the talus to glide posteriorly. Due to the wider front of the talus head, achieving the end range of dorsi flexion necessitates both superior and posterior glide of the distal fibula and anterior glide of the proximal fibula. The purpose of this study was to investigate the effects of tibiofibular joint mobilization on pain, range of motion, and balance in patients with lateral ankle sprains. Methods: Participants were randomly assigned to a control group (n=33) or an experimental group (n=31). Both groups underwent ankle joint mobilization three times a week for two weeks. Additionally, the experimental group received proximal and distal tibiofibular joint mobilization three times a week for two weeks. Measurements were obtained pre-intervention and post-intervention (after 2 weeks). Results: Evaluation parameters included the visual analog scale score (VAS), range of motion (ROM), and one-leg standing test (OLS). Post-intervention, both groups demonstrated significantly improved results for all assessments (p<.01). A significant intergroup difference was observed only in the ROM (p<.01) and OLS (p<.05). Conclusion: Our findings suggest that tibiofibular joint mobilization, combined with ankle joint mobilization, may be beneficial in enhancing outcomes for individuals with lateral ankle sprains.

PURPOSE: This study was conducted to investigate the effect of gluteal muscle strengthening exercises (GMSE) with ankle joint pumping exercises (AJPE) on thigh swelling, gait ability, and pain level in patients who underwent total hip arthroplasty. METHODS: A total of 38 patients who had undergone total hip replacement surgery >1 week prior participated in this study. Participants were randomly assigned to a group that performed only GMSE (CG; n = 19) and a group that performed GMSE and AJPE (EG; n = 19). The CG group performed GMSE for 30 min, and the EG group performed GMSE for 30 min followed by AJPE for 15 min. Exercises were performed five times a week, for a total of 20 times over 4 weeks in both groups. Thigh swelling (thigh size), 10 m walking test (10MWT) and timed up and go test (TUG) results, pain level (visual analogue scale, VAS) scores, Short Form 36 health survey (SF-36), and hip outcome scale (HOS) scores were evaluated before and after the intervention. RESULTS: After 4 weeks of intervention, significant differences were observed in the thigh size, 10MWT, TUG, VAS, SF-36, HOS before and after intervention in both groups (p < . 05). However, only thigh size showed a significant interaction between group and measurement time (p < . 05). CONCLUSION: GMSE combined with AJPE might be effective in improving the gait ability and pain level in patients with total hip arthroplasty, and GMSE may be more effective in improving thigh swelling and gait ability than GMSE without AJPE.
