Background: This study aimed to investigate ankle syndesmosis in healthy subjects under non-weight bearing (NWB) and weight bearing (WB) conditions using two US methods. Methods: The anterior tibiofibular clear space (ATFCS) was measured in healthy subjects in NWB and WB conditions using two US procedures. Method 1 measured 10 mm above the ankle joint and Method 2 measured 30° from the line of 10 mm above the ankle joint. Results: A total of 60 ankles from 30 subjects (male/female, 15/15) were included. There was a significant difference in the ATFCS between the two US methods (p < 0.001), and Method 2 was better at detecting the change in diastasis from NWB to WB conditions. The ATFCS was significantly greater on WB than on NWB, irrespective of the US method. Conclusions: Method 2 was better at detecting diastasis of the syndesmosis from NWB to WB conditions. The influence of WB needs to be considered when evaluating syndesmosis using US. Level of evidence: Cross-sectional cohort study; Level of evidence, Ⅳ

Posterior tibial translation (PTT) after double-bundle posterior cruciate ligament (PCL) reconstruction has sometimes occurred. Purpose of this study is to identify the risk factors for postoperative PTT after double-bundle PCL reconstruction with a hamstring autograft. Comparing the results of bilateral gravity sag view (GSV) at 12 months after surgery, over 5-mm PTT was defined as ‘failure’ in this study. Of 26 isolated PCL reconstruction cases, over 5-mm PTT was seen in 7 cases (group F: 9.57 ± 1.28 mm), and 19 cases had less than 5 mm (group G: 2.84 ± 1.29 mm). Age, sex, body mass index (BMI), preoperative GSV, posterior slope angle of the tibia, anterolateral bundle (ALB) and posteromedial bundle (PMB) graft diameters, and tibial tunnel diameter were evaluated. The two groups were compared with the 2 × 2 chi-squared test, the Mann Whitney U-test, and Spearman’s rank correlation coefficient. Multivariate logistic regression analysis was also performed to determine the risk factor. Statistical significance was indicated as p < 0.01 for correlation with postoperative PTT, and as p < 0.05 for all other comparisons. Mean age (group G 31.8 ± 12.5 vs group F 34.9 ± 15.9 years), sex (male/female: 15/4 vs 3/4), BMI (25.6 ± 4.6 vs 24.9 ± 3.9 kg/m<sup>2</sup>), preoperative GSV (11.3 ± 2.2 vs 11.6 ± 2.9 mm), PMB diameter (5.37 ± 0.33 vs 5.36 ± 0.48 mm), and tibial tunnel diameter (9.32 ± 0.58 vs 9.29 ± 0.49 mm) showed no significant differences. ALB diameter was significantly greater in group G (7.0 ± 0.5 mm) than in group F (6.5 ± 0.29 mm; p = 0.022). There was also a significant difference in posterior tibial slope angle (group G 9.19 ± 1.94 vs group F 6.54 ± 1.45, p = 0.004). On Spearman rank correlation coefficient analysis, ALB diameter GSV (correlation coefficient: − 0.561, p = 0.003) and posterior tibial slope angle (correlation coefficient: − 0.533, p = 0.005) showed a significant correlation with postoperative PTT. Multivariate logistic regression analysis showed that ALB diameter (OR 19.028; 95% CI 1.082–334.6; p = 0.044) and posterior slope angle of tibia (OR 3.081; 95% CI 1.109–8.556; p = 0.031) were independently associated with postoperative PTT, respectively. In double-bundle PCL reconstruction with hamstring, smaller ALB graft diameter and lower (flatted) tibial slope angle were considered risk factors for postoperative PTT.

Background: Alkaptonuria (AKU) is a rare hereditary disease. Ochronotic arthropathy, tendinopathy, and osteopenia/osteoporosis are generally musculoskeletal manifestations in patients with AKU. Because of the ochronotic tendinopathy and osteopenia, the surgical strategy for chronic ochronotic Achilles tendon rupture may be challenging. No studies have reported the surgical treatment of chronic Achilles tendon rupture in patients with AKU. Case presentation: We report a case of AKU that required surgical treatment for chronic Achilles tendon rupture. A 60-year-old woman was referred to our department for the assessment of left hindfoot pain that persisted for more than nine months after an ankle sprain. Three years prior to the first presentation to our hospital, she was diagnosed with AKU due to pigmented hip cartilage at the time of total hip arthroplasty. The patient was diagnosed as chronic Achilles tendon rupture based on the results of physical examination and magnetic resonance imaging (MRI). The MRI showed enlarged scar tissue of the Achilles tendon with an intrasubstance high signal intensity. We performed resection of the central part of the scar tissue (total length, 24 mm) followed by direct repair using the proximal and distal stumps of the scar tissue. The MRI at 12months after surgery showed continuity of the repaired Achilles tendon. At 18 months after surgery, the Achilles Tendon Total Rupture Score improved from 22 points preoperatively to 84 points postoperatively. The foot and ankle outcome score also improved. Conclusions: We reported a case of AKU with chronic Achilles tendon rupture in which direct repair using scar tissue between the tendon stumps was effective. Careful selection of the surgical procedure for the treatment of chronic ochronotic Achilles tendon rupture is recommended because of concomitant ochronotic tendinopathy and osteopenia/osteoporosis.

【はじめに】ステロイド薬は他薬との薬物相互作用が比較的少なく汎用されるが，抗結核薬のリファンピシン（以下RFP）との相互作用はあまり知られていない．ネフローゼ症候群加療中に非結核性抗酸菌症（以下NTM）を合併し，ステロイドとRFPの併用で原疾患およびNTMの治療に難渋した1例を経験した．【症例】41歳男性，21歳時にネフローゼ症候群と診断され，ステロイドを内服中に手関節掌背側の腫脹を認め，滑膜切除術後に非結核性抗酸菌性滑膜炎の診断となった．RFPを含む抗結核薬3剤を開始したところ，ネフローゼ症候群が悪化しステロイドを増量，尿蛋白は改善するも手関節腫脹が再発し，2回目の滑膜切除術施行後，高気圧酸素療法で感染は鎮静化した．【考察】NTMにはRFPが汎用されるが，ステロイドとの相互作用により治療に難渋することがある．薬物の相互作用を十分に熟知し，NTMの治療にあたる必要がある．
