Preliminary results of stabilization of far distal tibia fractures with the distal tibial nail: A prospective, multicenter case series study

IntroductionThe distal tibial nail (DTN) is a novel retrograde intramedullary nail used for distal tibial fracture stabilization. We investigated the clinical results of DTN use for distal tibial fractures and compared them with those reported in the literature on locking plates and antegrade intramedullary nails. Materials and methodsThis multicenter, prospective, observational cohort study examined distal tibial fractures with AO/OTA classification 43 types: A1, A2, A3 or C1. The primary outcomes included bone union rate, soft tissue problems, and surgical complications. Secondary outcomes were EuroQol-5 Dimension-5 Level (EQ-5D-5L), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot clinical scores 1 year postoperatively. Incidence of varus or valgus/anterior-posterior flexion deformity with a difference of ≥5° and postoperative reduction loss rate were evaluated. ResultsFive men and five women were enrolled (mean age, 69 years [range, 30–77 years]), including one open-fracture-type Gustilo type IIIB case. Bone union was observed in all patients at 6 months postoperatively. Delayed union, leg edema, and guide pin breakage were observed in three, one, and one cases, respectively. No soft tissue or surgical complications were observed. During the final follow-up, the EQ-5D-5L, SAFE-Q, and AOFAS hindfoot scores were 0.876 (0.665–1.0), 83–92, and AOFAS 92.6 (76–100), respectively. Varus and retroflexion deformities were observed in one case each. DiscussionDTN has been reported to have biomechanically equivalent or stronger fixation strength than locking plates or antegrade intramedullary nails. In addition, while DTN was thought to be less invasive for soft tissue and can avoid injury to the knee, it was thought that care should be taken to avoid medial malleolus fractures and posterior tibialis tendon injuries. Comparisons with literature treatment results for locking plates and antegrade intramedullary nails showed comparable to advantageous results. ConclusionsDTN treatment results for distal tibial fractures were as good as those for locking plates and antegrade intramedullary nails. DTN is useful for stabilization and does not compromise the surrounding soft tissues.

Treatment of Symptomatic Os Supranaviculare in Athletes.

Although the incidence of os supranaviculare (OSSN) is generally low, symptomatic OSSN affects athletes. The aim of this study was to assess the variations of OSSN and the results of osteosynthesis between the OSSN and the navicular bone. Eleven feet of 10 elite athletes with symptomatic OSSN were treated. There were 3 male and 7 female patients with an average age of 19 years. Eight feet exhibited navicular stress fracture (NSF). Operative treatment was performed in 9 feet of 8 patients and 2 conservatively. Seven OSSNs were fixed with 1 or 2 screw(s) according to their size, using an autologous bone graft. The accompanying NSF was also treated surgically in 4 feet. Foot condition was evaluated using the Japanese Society for Surgery of the Foot (JSSF) midfoot rating scale and sports activity score of the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). The median OSSN was 12.7 mm in width, 5.6 mm in length, and 6.6 mm in height. The dorsal surface of the OSSN required at least 70 mm2 to be fixed using 2 screws. Seven OSSNs of 6 patients treated surgically successfully fused with the navicular. Two small OSSNs that were not stabilized with screws also fused after surgical treatment for NSF. However, one of the 2 OSSNs with NSF treated nonoperatively did not achieve fusion. The patients were followed up for 24-161 months. The median JSSF score improved from 87 to 97.7 postoperatively (P = .00312). The median postoperative SAFE-Q sports score was 84.8. All patients returned to their original activities. Our results suggest that osteosynthesis with autologous bone graft was effective for symptomatic OSSNs. Even when the OSSN was small and not suitable for internal fixation, treatment of NSF was effective for union of OSSNs. The OSSN possibly belongs to a part or subtype of NSF. Level IV, retrospective case series.

Short-term efficacy and limitations of foot care in patients with rheumatoid arthritis.

Foot and ankle impairments are major issues in patients with rheumatoid arthritis (RA). Foot deformities often lead to skin disorders, such as callosities, ingrown toenails, and interdigital tinea pedis. This study was aimed at investigating the efficacy and limitations of foot care by experts in patients with RA. Thirty-one patients with RA who began receiving foot care from nurses at our institution between September 2020 and February 2023 were included. Responses to a survey using the self-administered foot evaluation questionnaire (SAFE-Q) for patient-reported outcome measures were compared at baseline, the second visit (1.3 ± 0.5 months after baseline), and the third visit (3.6 ± 1.6 months after baseline). Scores for 'Pain and pain-related' and 'General health and well-being' components of SAFE-Q markedly improved after foot care. On the other hand, there were no significant differences in the scores for 'Physical functioning and daily living', 'Social functioning', and 'Shoe-related' components during observation periods. Foot care for rheumatoid feet is effective in providing pain relief and improving general health and well-being. However, physical and social functioning and footwear issues did not improve. Clinicians must understand the effects and limitations of foot care in patients with RA.

Arthroscopic Modified Lasso-Loop Stitch Technique for Chronic Lateral Ankle Instability in Skeletally Immature vs Mature Patients.

In recent years, arthroscopic lateral ankle ligament repair has become increasingly popular. However, reports on the clinical outcomes of arthroscopic ankle stabilization for skeletally immature patients remain scarce. This study investigated the clinical outcomes of arthroscopic lateral ankle ligaments repair in skeletally immature patients compared to skeletally mature patients. Our retrospective analysis compared skeletally immature patients and skeletally mature adults who underwent arthroscopic repair of the ankle lateral ligaments with a modified lasso-loop stitch using a suture anchor. Skeletal immaturity was defined as patients whose epiphyseal line of the distal fibula remained open on plain radiography. Clinical outcomes were evaluated using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) at 2 years after surgery. The time to postoperative walking, jogging, and return to full sports activities were also evaluated. Sixty-four skeletally immature patients (IM group) and 103 skeletally mature adults (M group) were included. No significant differences were observed during both walking and jogging after surgery between the groups; however, return to full athletic activities was significantly earlier in IM group (P = .05). The mean scores in all SAFE-Q subscales significantly improved in both groups after surgery (P < .001). There were also no statistically significant differences between the groups in the mean postoperative SAFE-Q scores for all subscales. All patients in the IM group returned to playing sports at their preinjury levels postoperatively. We found that skeletally immature patients with chronic lateral ankle instability had generally similar responses to arthroscopic lateral ankle as skeletally mature adult patients at minimally 2 years' follow-up with a high rate of successful return to sport. Level III, retrospective case control study.

Long-term outcomes of first metatarsophalangeal hemiarthroplasty for hallux rigidus

Hallux rigidus (HR) is arthritis of the first metatarsophalangeal joint.First metatarsophalangeal joint hemiarthroplasty surgery is one of the treatment options for end stage hallux rigidus.The aim of this study is to evaluate the long-term outcomes of hemiarthroplasty of the first MTPJ with a metallic implant in patients with end-stage HR. Patients who underwent hemiarthroplasty surgery with the diagnosis of HR were included in the study. Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and Foot and Ankle Disability Index (FADI) scores were used in pre-operative and post-operative final follow-ups to evaluate the clinical status of the patients. Post-operative 1st metatarsophalangeal joint range of motion was measured and recorded separately for each patient. The intra-hospital and follow-up complications and revision surgeries of the patients were recorded. Thirty-five patients with a mean follow-up of 8.1 years were included in the study. There was a statistically significant positive change in both FADI and SAFE-Q scores compared to the pre-operative process(p = 0.0001). The average dorsiflexion angle at the final follow-up was 22.0 ± 8.2. Thus, it was determined that the 5-year and 8-year survival rates of patients in this study were 97.1% and 87.8%, respectively. In conclusion, the long-term results show that the use of hemiarthroplasty in the treatment of end-stage HR leads to high patient satisfaction, increased range of motion and a high survival rate.

Early full weight-bearing and gait exercise after cemented total ankle arthroplasty with modified antero-lateral approach.

According to the conventional postoperative procedure after total ankle arthroplasty (TAA) against end-stage osteoarthritis (OA) and rheumatoid arthritis (RA), mobilization and weight-bearing is currently started after completion of wound healing. Recently, early mobilization for dorsiflexion after TAA with modified antero-lateral approach was reported to be feasible and safe. To investigate the further possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early full weight-bearing and gait exercise after cemented TAA utilizing a modified antero-lateral approach. This retrospective, observational study investigated 23 consecutive ankles (OA: 14 ankles, RA: 9 ankles) that had received cemented TAA with a modified antero-lateral approach. These ankles were divided into three groups [1. conventional postoperative protocol: 8 ankles, 2. early dorsiflexion protocol: 7 ankles, 3. early dorsiflexion+full weight-bearing protocol: 8 ankles]. In group 3, after early dorsiflexion mobilization (day 3), full weight-bearing/gait exercise was started from 7 days after surgery (10 days after if malleolar osteotomy was added). Postoperative wound complications were observed and recorded. Number of days for hospitalization was also evaluated. Range of motion (ROM) of dorsiflexion/plantar flexion was measured. Patients also completed a self-administered foot evaluation questionnaire (SAFE-Q) and the scale of Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot score preoperatively and at final follow-up. No postoperative complications related to wound healing were observed even after early full weight-bearing and gait exercise. Days for hospitalization was significantly shortened in early full weight-bearing and gait exercise group (group 3) from 35-38 days to 24 days. ROM for both dorsiflexion and plantar flexion significantly increased in group 3, furthermore all indices of SAFE-Q score also showed stronger significant improvement in group 3. JSSF score improved significantly after TAA in all groups. Within this small number of cases, early full weight-bearing and gait exercise from 7 days after cemented TAA was feasible and safe with the modified antero-lateral approach. Combination of early dorsiflexion mobilization and weight-bearing/gait exercise contributed to shortening the hospitalization day, and improving ROM for both dorsiflexion and plantar flexion after surgery. Innovations in postoperative procedures for rehabilitation after TAA can be expected.

Anterior Ankle Impingement Syndrome With Spur Fragmentation: Is It an Os Talotibiale?

Bone fragments are often found in ankles with anterior bony impingement. However, whether they are detached osteophytes or accessory bones remains unknown. Among the 66 continuously enrolled cases of ankles with anterior bony impingement, 32 had a fragment located at the anterior margin of the tibia. The cases of posterior impingement, lateral instability, osteochondral lesions, or free bodies simultaneously treated were excluded. The enrolled subjects were classified into 2 groups: ankles without (group A) and with remarkable spurs (group B). The patients' backgrounds, location of the fragments, clinical scores, and other parameters required to resume sports were compared. The Japanese Society for Surgery of the Foot (JSSF) ankle rating scale was used to evaluate preoperative and postoperative ankle conditions, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) was used to evaluate postoperative sports abilities. Eight (seven subjects) and 11 ankles were classified into groups A and B, respectively, and the mean age of the 18 patients was 25.4 (range, 16-37) years. No statistical differences in patient backgrounds or fragment sizes between the groups existed. In group A, the fragments were located on the lateral plateau in 7 of the 8 ankles, whereas in group B, their locations varied. The patients were followed up for a median of 48 months (range, 24-168). No complications were observed. The postoperative JSSF and SAFE-Q sports activity scores were significantly higher in group A than in group B (P <.01 and <.001, respectively). The postoperative term to return to their original sports activities was significantly shorter in group A (P < .05). Anterior bony fragments of the ankle without a remarkable spur were located at a specific site, and the results of arthroscopic treatment were better than in those with remarkable spurs. Such a fragment may be called an os talotibiale. Level III, retrospective cohort study.

Proximal Supination Osteotomy for Hallux Valgus: Comparison of Clinical and Radiologic Outcomes for the Most Severe Deformities.

There is little available information regarding the difference in outcomes between severe hallux valgus (S-HV), defined as 40 degrees ≤ hallux valgus angle (HVA) < 50 degrees, and what we consider to be "super-severe HV" (SS-HV), defined as >50 degrees, following a proximal metatarsal osteotomy. We aimed to retrospectively compare the outcomes of a proximal metatarsal osteotomy in S- and SS-HV. The series consisted of 57 female patients (57 feet) treated with a proximal supination osteotomy for symptomatic S- and SS-HV (33 and 24 feet, respectively). The outcome measures included radiographic parameters and for 45 patients included the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) score, and a visual analog scale pain score (VAS-PS) preoperatively and at a minimum follow-up of 12 months with a median of 26 months. No significant differences were found in age, body mass index, and the duration of follow-up between patients with S-HV and SS-HV (P > .10 for all comparisons) with the numbers available. Preoperative HVA in patients with S- and SS-HV was significantly improved at the final follow-up (P < .0001 for both comparisons). No significant differences in postoperative HVA and IMA were observed between patients with S- and SS-HV (P = .51 and .50, respectively). All 5 preoperative subscale scores of SAFE-Q in patients with S- and SS-HV significantly improved postoperatively (P < .01 for all comparisons). Preoperative VAS-PS in patients with S- and SS-HV significantly improved postoperatively (P < .0001 and <.009, respectively). There were no significant differences in preoperative and postoperative scores of all the SAFE-Q subscales and VAS-PS between patients with S-HV and SS-HV (P > .10 for all) with the numbers available. We found for this patient group that a proximal supination osteotomy can achieve a large correction for SS-HV as well as S-HV and significantly improve radiologic and clinical outcomes in SS-HV. The outcomes between patients with S- and SS-HV were not different in this series. Level III, retrospective comparative study.

Characteristics of Nonunion After Arthroscopic Ankle Arthrodesis: A Multicenter Retrospective Cohort Study

Nonunion is a major complication of arthroscopic ankle arthrodesis. However, the characteristics and risk factors of nonunion are not well understood. This retrospective multicenter observational study aimed to clarify the characteristics of nonunion after arthroscopic ankle arthrodesis. We included 154 patients who underwent arthroscopic ankle arthrodesis at any 1 of 5 institutions. Patients were divided into 2 groups: union and nonunion, and the groups were compared. Age, sex, body mass index, diabetes, smoking, corticosteroid use, diagnosis, treatment information, treatment protocol, radiographic evaluation, and patient-reported outcomes were recorded and analyzed. On radiographs, bony union was observed in 142 ankles (91.0%) but not in 12 ankles (9.0%). Postoperative radiographic tibial bony gap (mm) was significantly larger in the nonunion group (medial = 1.98, center = 1.65, anterior = 2.21, middle = 1.72, posterior = 3.01) than in the union group (medial = 1.35, center = 1.13, anterior = 1.28, middle = 1.03, posterior = 2.03). Furthermore, the visual analog score (VAS) of pain and pain-related self-administered foot evaluation questionnaire (SAFE-Q) subscale score significantly worsened in the nonunion group (VAS = 3.83, SAFE-Q subscale score = 69.8) compared to that in the union group (VAS = 1.35, SAFE-Q subscale score = 76.6). A larger radiographic tibiotalar bony gap was observed in the nonunion group. Other measurement outcomes were not associated with nonunion. Additionally, patient-reported outcomes markedly worsened in the nonunion group.

Relationship between pain and intra-articular pathology in patients with chronic lateral ankle instability.

Repeated ankle sprains can lead to chronic lateral ankle instability (CLAI). It is unclear whether CLAI causes pain unless complicated by intra-articular lesions. This study aimed to analyze the characteristics of pain and the relationship between pain and intra-articular pathology in patients with CLAI. Fifty-three ankles in 46 patients with CLAI who had undergone surgery were retrospectively reviewed. The self-administered foot evaluation questionnaire (SAFE-Q) was given to patients the day before surgery. Intra-articular lesions were assessed using arthroscopy and magnetic resonance imaging (MRI). In addition, the Hounsfield Unit (HU) on computed tomography (CT) of the medial gutter was measured. The relationship between pain and intra-articular findings was also analyzed. The pain and pain-related scores in the SAFE-Q were significantly correlated with synovitis in 96.3% (rs = - 0.532). HU ratios in the tibia and talus were also significantly correlated with pain (rs = - 0.603, - 0.534, respectively). The arthroscopic synovitis score and HU ratios in patients with high pain scores were significantly higher than those in patients with low pain scores. Forty ankles (75.5%) had synovitis and articular cartilage injuries were observed in 22 ankles (41.5%). Patients with fluid collection or bone marrow lesions (BML) scored significantly lower in pain than those without, but there was no significant difference between patients with and without cartilage injury. Multiple regression analysis revealed that a high synovitis score and HU ratio of the talus were significantly associated with high pain. Intra-articular lesions such as synovitis and BML were associated with pain in patients with CLAI. Osteosclerotic changes in the medial gutter also induced ankle pain, indicating that osteoarthritic changes had already begun. Therefore, lateral ankle ligament injuries after ankle sprain should be appropriately treated to avoid secondary degenerative changes.

Clinical outcomes of arthroscopic lateral ligament repair using a knotless anchor for chronic lateral ankle instability

Background/objectiveArthroscopic lateral ligament repair (ALLR) for chronic lateral ankle instability (CLAI) has been improving with technical innovations. However, there is a lack of information regarding mid- and/or long-term clinical outcomes after the introduction of ALLR. This study aimed to report mid-term clinical outcomes of ALLR with a knotless anchor. MethodsThirty-two patients (11 men and 21 women; mean age, 28 ± 14 years) who underwent ALLR with a knotless anchor from December 2015 to October 2020 were included. The mean follow-up period was 31 ± 11 months. The Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were used for clinical evaluation preoperatively and at the 2-year follow-up. Surgical complications, particularly knot irritation, were also examined. ResultsThe JSSF scale scores were significantly improved, from 71.3 ± 13.1 preoperatively to 96.6 ± 5.1 postoperatively (P < 0.05), and the SAFE-Q showed similar improvement in all subscales (P < 0.05). One case had a complication of persistent pain around the lateral portal (3.1%). ConclusionALLR using a knotless anchor provided satisfactory clinical outcomes over 2 years, and no major complications, such as knot irritation, were observed. Case seriesLevel of Evidence, 4.

Treatment of Intra-Articular Lesions After Posterior Inferior Tibiofibular Ligament Injury: A Case Series of Elite Rugby Players.

Surgical intervention is not typically used to treat symptoms after mild tibiofibular ligament injuries without ankle dislocation or subluxation. To describe outcomes in patients arthroscopically treated for unique intra-articular lesions after sustaining syndesmosis injury of the ankle. Case series; Level of evidence, 4. A total of 11 elite male rugby players with a mean age of 21.0 years (range, 17-28 years) were referred to our hospital for prolonged posterior ankle pain after a high ankle sprain during rugby football. The patients were examined using standing view radiography, computed tomography (CT) and magnetic resonance imaging (MRI) to determine the extent of ligament damage. Posterior ankle arthroscopy was performed to examine intra-articular lesions. The patients were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle/hindfoot rating scale and sports activity score of the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). The average reduced tibiofibular overlap on the standing mortise view was 1.2 mm (range, 0.5-2.0 mm) compared with the opposite ankles. Mason type 1 fracture was detected on CT in 6 patients, and ossification of the interosseous membrane was detected in 2 patients. A bone bruise in the posterior malleolus was observed on MRI in all but 1 patient. Intra-articular fragments located in the posterior ankle were observed and removed arthroscopically. Symptoms improved rapidly after arthroscopic treatment in all patients. All patients returned to rugby games at a median of 11 weeks postoperatively. The median AOFAS scores improved from 77 preoperatively to 100 postoperatively (P < .01), and the median SAFE-Q sports activity subscale score improved from 49.4 to 100 (P < .01). All unique intra-articular lesions that developed in rugby football players after syndesmosis injury were able to be treated arthroscopically. Patients returned to playing rugby football without syndesmosis reduction. Posterior ankle arthroscopy was effective in patients with residual symptoms after syndesmosis injury.

Hindfoot Alignment and Ankle Stability Following Arthroscopic Lateral Ankle Ligament Repair.

Hindfoot varus deformity is a known risk factor for chronic lateral ankle instability (CLAI). The impact of this deformity on clinical results following arthroscopic lateral ankle ligament repair (ALLR) for CLAI has not been studied. Sixty-three ankles from 62 patients who received ALLR for CLAI were retrospectively examined. Preoperative plain radiographs were used to measure tibial articular surface (TAS) angles, and long axial hindfoot alignment radiographs were used to measure tibiocalcaneal angles (TCAs) pre- and postoperatively. Results included ratings on the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and recurrent ankle instability (respraining of the operated ankle following surgery). Recurrent ankle instability, defined as incidence of any new ankle sprain after surgery reported in the follow-up period, occurred in 13 ankles. The TAS angles of these patients were significantly low, and their preoperative TCA was significantly high. Multivariate analysis showed that preoperative TCA was an independent risk factor for recurrent ankle instability. The threshold values for preoperative TCA for recurrent instability were determined via the receiver operating characteristic curve analysis to be 3.4 degrees. Patients were assigned to a low- or high-TCA group based on the reported average TCA (2.7 degrees) of healthy patients. In the high-TCA group, recurrent instability was significantly more frequent, and the scores on the pain subscale of the postoperative SAFE-Q were significantly lower. Hindfoot varus alignment was associated with pooreroutcomes after ALLR. Level III, retrospective comparative study.

Early mobilization of dorsiflexion from 3 days after cemented total ankle arthroplasty with modified antero-lateral approach

BackgroundAccording to the conventional postoperative procedure after total ankle arthroplasty (TAA), mobilization is currently started after completion of wound healing. To investigate the possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early mobilization of dorsiflexion after cemented TAA utilizing a modified antero-lateral approach. Materials and methodsThis retrospective, observational study investigated 14 consecutive ankles that had received cemented TAA. Mobilization of dorsiflexion was started from 3 days after surgery. Postoperative wound complications including blister formation, eschar formation, wound dehiscence, peri-incisional decreased sensation were observed and recorded. Range of motion (ROM) of dorsiflexion/plantar flexion was measured. Patients also completed a self-administered foot evaluation questionnaire (SAFE-Q) and the scale of Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot score preoperatively and at final follow-up. ResultsNo postoperative complications related to wound healing were observed. ROM for dorsiflexion, SAFE-Q score, and JSSF score improved significantly after TAA. ConclusionWithin this small number of cases, early mobilization of dorsiflexion from 3 days after cemented TAA was feasible and safe with the modified antero-lateral approach. Innovations in postoperative procedures for rehabilitation after TAA can be expected.

Risk Factors for the Recurrence of Instability After Lateral Ankle Ligament Repair.

Arthroscopic anterior talofibular ligament (ATFL) repair is widely performed for chronic lateral ankle instability (CLAI). Although many studies have reported excellent outcomes with this procedure, the recurrence of instability remains a common concern. Therefore, this study aimed to analyze the risk factors for the recurrence of instability after arthroscopic repair for CLAI. Fifty-six ankles of 53 patients with a mean age of 31.8 ± 14.7 years were retrospectively reviewed. All patients underwent arthroscopic ATFL repair. If instability remained immediately after ATFL repair, calcaneofibular ligament (CFL) repair was performed. The Ankle Activity Score (AAS) was assessed preoperatively, and clinical outcomes including the Japanese Society for Surgery of the Foot scale, Karlsson-Peterson scores, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were evaluated preoperatively and at the final follow-up. Talar tilt angle (TTA) was assessed preoperatively and 1 year postoperatively. Ankles were divided into 2 groups-nonrecurrence (postoperative TTA, <6 degrees) and recurrence (postoperative TTA, ≥6 degrees)-and clinical outcomes were compared. Sixteen ankles showed recurrent instability, whereas 40 did not. AAS, TTA, and social functioning in the SAFE-Q were significantly higher in the recurrence group than those in the nonrecurrence group preoperatively. In addition, the rate of poor ATFL remnant quality and the number of CFLs not repaired despite the preoperative injury diagnosis were significantly higher in the recurrence group than in the nonrecurrence group. Arthroscopic repair for ATFL and CFL deficiencies with preoperative high activity, poor remnant quality, and neglected CFL injury can result in the recurrence of instability. Appropriate surgical procedures to prevent the recurrence of instability should be selected for these ankles. Level IV, retrospective case series.

Association of Preoperative Depression Score With Outcomes of Transfibular Total Ankle Arthroplasty

Favorable short-term results of transfibular total ankle arthroplasty have been reported in several studies; however, the factors affecting these results have not been elucidated. This study aimed to determine whether preoperative depression affects the outcome of transfibular total ankle arthroplasty and whether depression changes with surgery. Scores from the Japanese Society of Surgery of the Foot Ankle/Hindfoot scale (JSSF scale), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), Hospital Anxiety and Depression Scale (HADS), and Timed Up & Go test (TUG) were collected preoperatively, at 6 months-, and at 1 year postoperatively from 20 patients. Eighteen patients were diagnosed with osteoarthritis and two patients with rheumatoid arthritis. The mean age of the patients was 75 years. Patients were divided into two groups: those with preoperative HADS depression scores above the median (higher depression score group) and below the median (lower depression score group), and intergroup comparisons were made. No significant differences were observed in the JSSF and TUG scores between the groups, both preoperatively and postoperatively. Meanwhile, the SAFE-Q pain subscale score was significantly lower in the higher depression score group than in the lower depression score group (median, 59 vs. 90) 1 year postoperatively. There were no differences in the other SAFE-Q subscale scores between the groups. The results suggested that depressive tendencies did not affect postoperative functional results using objective assessment measures but had a negative impact on pain in subjective assessment measures.

Clinical outcomes of surgical treatment for end-stage ankle osteoarthritis in patients aged ≥ 75 years: a multicenter, retrospective study

BackgroundThis study aimed to clarify the clinical outcomes of surgical treatment for end-stage ankle osteoarthritis in patients aged ≥ 75 years and compare these outcomes with those of patients aged < 75 years.MethodsA total of 148 patients, including 65 who underwent total ankle arthroplasty and 83 who underwent ankle arthrodesis, were retrospectively surveyed. Clinical outcomes were assessed preoperatively and at the last follow-up using the Japanese Society for Surgery of the Foot Hindfoot Scale and a self-administered foot evaluation questionnaire (SAFE-Q). Patient characteristics, including age, sex, body mass index, radiographic severity, and follow-up period, were also assessed. The patients were divided into older (≥ 75 years) and younger (< 75 years) age groups. Improvements in outcomes were then compared between age groups using univariate analysis and analysis of covariance adjusted for patient characteristics. Total ankle arthroplasty and ankle arthrodesis were analyzed separately.ResultsAll clinical outcome scores improved postoperatively in the older age groups for both procedures. Scores for the pain and pain-related subscale of the SAFE-Q improved by 37 points (p < 0.001) in post-total ankle arthroplasty patients and by 35 points in post-ankle arthrodesis patients (p < 0.001). Furthermore, multivariate analysis showed that the improvements observed in all scores were not different between the older and younger age groups for both post-total ankle arthroplasty and post-ankle arthrodesis patients, except for the SAFE-Q physical functioning subscale score for post-ankle arthrodesis patients. The clinical outcomes improved significantly in post-total ankle arthroplasty and post-ankle arthrodesis patients aged ≥ 75 years. Moreover, these improvements were similar to those observed in patients aged < 75 years.ConclusionsSurgical treatment of end-stage ankle osteoarthritis can be a viable treatment option, even in elderly patients, and can be expected to improve similarly to younger patients.

Cross-cultural adaptation and validation of a Spanish version of the self-administered foot evaluation questionnaire (SAFE-Q)

BackgroundThe self-administered foot evaluation questionnaire is a comprehensive measure for assessing the perception of patients regarding their foot-related problems. However, it is currently only available in English and Japanesse. Therefore, this study aimed to cross-culturally adapt the questionnaire to Spanish and assess its psychometric properties. MethodsThe methodology recommended by the International Society for Pharmaco Economics and Outcomes Research for translating and validating patient-reported outcome measures was followed for the Spanish translation. After a pilot study with 10 patients and 10 controls, an observational study was carried out between March and December 2021. The Spanish version of the questionnaire was filled by 100 patients with unilateral foot disorders, and the time spent to complete each questionnaire was recorded. Cronbach's alpha was calculated to analyze the internal consistency of the scale and Pearson's correlation coefficients for the degree of inter-subscale associations. ResultsThe maximum correlation coefficient for the Physical Functioning, Daily Living, and Social Functioning subscales was 0.768. The inter-subscale correlation coefficients were significant (p < 0.001). Additionally, the value of Cronbach's alpha for the whole scale was 0.894 (95% confidence interval, 0.858–0.924). The values of Cronbach's alpha varied between 0.863 and 0.889 when the value of one of the five subscales was suppressed, which can be considered a measure of good internal consistency. ConclusionThe Spanish version of the questionnaire is valid and reliable. The method followed for its transcultural adaptation ensured its conceptual equivalence with the original questionnaire. Health practitioners can use the self-administered foot evaluation questionnaire as a complementary method to assess the interventions performed for ankle and foot disorders among native Spanish speakers; however, further research is necessary to assess its consistency for use by populations from other Spanish-speaking countries.

Quality of life in Werner syndrome and associated subjective foot/ankle symptoms: A cross-sectional survey.

The aims of this study were to assess the general quality of life and foot/ankle health-related quality of life among subjects with Werner syndrome (WS) and to determine subjective foot/ankle symptoms associated with quality of life. Using a questionnaire survey, patients were asked to provide information on age, sex and presence of subjective symptoms and complete both the 36-Item Short Form Health Survey (SF-36) questionnaire and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). Statistical analyses were performed using Student's t-test, the Mann-Whitney U test, Fisher's exact test and Spearman's rank correlation. Data from 12 patients with an average age of 54 ± 8.6 years were analyzed. The mean SF-36 score for the domain of physical functioning was 21.2; for role-physical function, 32.6; for bodily pain, 38.5; for general health, 34.4; for vitality, 44.8; for social function, 38.5; for role-emotional function and for mental health, 46.7. The mean mental component summary was as high as the national standard, but it was low in men. The mean SAFE-Q scores were also low. Patients with ulcers had significantly more pain and low general health perception. As compared with the national standard, the role/social component score was not low, and there was a correlation in most domains of the SAFE-Q. In WS, the general health-related quality of life was low overall in the physical domain and low only in men for the mental domain, whereas it was low in the social domain when foot/ankle health-related quality of life was low.

Total Talar Replacement for Idiopathic Osteonecrosis of the Talus: Investigation of Clinical Outcomes, Pain, ADL, QOL

Treatment of osteonecrosis of the talus is challenging. Nonoperative management includes nonweightbearing treatment. Various types of hindfoot fusion procedures have been performed, but delayed union and shortening of the operated leg have reportedly occurred. In contrast, talar body prosthesis is a surgical procedure with potential that relieves pain, restores ankle joint function, and is not associated with leg-length discrepancy. The aim of this study was to investigate postoperative pain, clinical outcomes, activities of daily living (ADL), and quality of life (QOL) after total talar replacement in patients with osteonecrosis of the talus. Ten ankles in 10 patients with idiopathic osteonecrosis of the talus who were treated with a total talar replacement between 2007 and 2015 were included in the investigation. Scores according to the visual analog scale (VAS), Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, Functional Independence Measure (FIM), and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were assessed. The VAS score significantly improved from a mean of 80 ± 8 points before surgery to 18 ± 22 points after surgery (P < .01). The JSSF ankle-hindfoot scale score significantly improved from a mean of 53 ± 12 points before surgery to 89 ± 7 points after surgery (P < .01). The FIM score significantly improved from a mean of 122 ± 1 points before surgery to 125 ± 1 points after surgery (P < .01). The mean postoperative SAFE-Q scores were as follows: 81 ± 10.3 points for pain, 78 ± 14.7 points for physical function, 90 ± 12.4 points for social function, and 83 ± 15.4 points for shoe-related. Total talar replacement is a useful treatment for patients with osteonecrosis of the talus. This replacement surgery preserves the function of the ankle and subtalar joints, and improves pain, ADL, and QOL. Level IV, case series.
