As the time since injury was more than 6 weeks in all of the patients, they were categorized as having chronic MKI. Patients were assessed clinically for laxity, and the diagnosis was confirmed radiologically. Ipsilateral hamstring tendons were used for medial collateral ligament (MCL) or posterolateral corner reconstruction in a patient with Schenck knee dislocation (KD) type III. In these cases, the posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) were reconstructed by using the peroneus longus and contralateral hamstring tendons respectively. Ipsilateral hamstring tendons were used for ACL reconstruction and an ipsilateral peroneus longus tendon graft was used for reconstruction of the PCL in a KD type II injury. In two cases of KD type IV injury, the lateral laxity was only grade II and was managed conservatively; the rest of the ligaments were addressed like a KD type III injury.

This study aims to determine if short-duration chemoprophylaxis after TKA reduces the incidence of VTE in an Asian population.</p><p><strong>Methods: </strong>A retrospective study of 316 patients who underwent unilateral primary TKA between 1 January 2011 and 31 December 2013 was conducted. All patients received mechanical prophylaxis. One hundred seventeen patients (37%) received additional chemoprophylaxis, whereas 199 patients (63%) did not. A Doppler ultrasound (DUS) of both lower limbs was conducted for all patients within 6 days after surgery (median = 3 days) to assess for both proximal and distal DVT. Chemoprophylaxis in the form of enoxaparin (low molecular weight heparin; LMWH), aspirin, or heparin was administered until patients had a normal DUS, for a median duration of 4 days. Patients were followed up clinically for a minimum of 6 months to monitor for delayed or recurrent VTE and at least 2 years for patient-reported outcome measures.</p><p><strong>Results: </strong>Overall, 24 patients (7.59%) developed deep vein thrombosis (DVT): three proximal and 21 distal DVTs. Twenty-three of the 24 patients were asymptomatic. Twenty of 199 patients (10.05%) with only mechanical prophylaxis developed DVT, whereas four of 117 patients (3.42%) with additional chemoprophylaxis developed DVT. Multivariate analysis showed that chemoprophylaxis use was associated with reduced incidence of DVT (odds ratio = 0.19, p value = 0.011). Other factors associated with increased DVT incidence include female gender (odds ratio = 5.45, p value = 0.034), positive history of cancer (odds ratio = 5.14, p value = 0.044), and increased length of stay in hospital (odds ratio = 1.19, p value < 0.001).</p><p><strong>Conclusions: </strong>Our study has shown that despite the low incidence of DVT in Asian patients undergoing TKA, short-duration chemoprophylaxis might be effective in reducing the incidence of DVT. However, most DVTs observed in our study were distal and may be of limited clinical significance. Further studies are needed to investigate the impact of chemoprophylaxis use on the incidence of PE and overall mortality rates among Asian patients.</p>","PeriodicalId":17886,"journal":{"name":"Knee Surgery & Related Research","volume":"32 1","pages":"58"},"PeriodicalIF":3.1,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1186/s43019-020-00077-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38566210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the use of tissue adhesive after hip and knee arthroplasty has been described. We believe that knee arthroplasty wounds exhibit different behavior compared to hip arthroplasty due to the increased wound-margin tension associated with knee flexion.</p><p><strong>Patients and methods: </strong>Forty-three patients undergoing total knee arthroplasty (TKA) by a single surgeon were studied. All wounds were closed using staples with or without tissue adhesive. Post-operatively, the wounds were reviewed daily for ooze. Dressings were changed only if soaked > 50% or if there was persistent wound discharge of more than 2 × 2 cm at 72 h.</p><p><strong>Results: </strong>There were 21 patients in the tissue adhesive (group 1), 22 in the non-tissue adhesive (group 2) with the average age for group 1 of 72.2 years and for group 2 of 69.3 years. The median length of stay for both groups was 4 days (range of 3-7 days for group 1 and 2-6 days for group 2) (P = 0.960). The tissue adhesive group showed a statistically significant reduction in wound ooze on day 1 (P = 0.019); however, the difference was not significant on the following days. The median for the number of dressing changes for group 1 was zero changes and for group 2, one change. This was not statistically significant (P = 0.112). No complications were observed in both groups and there were no reactions to the tissue adhesive.</p><p><strong>Conclusion: </strong>The data from this case series suggest that the use of tissue adhesive may reduce wound ooze on day 1 only. The latter is most likely due to significant tensile forces to which the knee arthroplasty wound is subjected in the immediate post-operative rehabilitation. Further, the cost of tissue adhesive is not offset by reduced dressing changes or length of hospital stay.</p>","PeriodicalId":17886,"journal":{"name":"Knee Surgery & Related Research","volume":"32 1","pages":"57"},"PeriodicalIF":3.1,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1186/s43019-020-00073-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38551737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
