RESUMO
Background@#The aim of this study was to investigate the clinical characteristics of nontuberculous mycobacterial tenosynovitis and to report the process of diagnosis and the outcomes of surgical debridement and drug administration in South Korea. @*Methods@#Between 2010 and 2019, 23 patients (10 men and 13 women) with nontuberculous tenosynovitis of the hand were treated at two centers. Their average age was 64 years, and the average duration of symptoms was 8 months (range, 1–36 months).Eight patients had a history of trauma or surgery. The average number of corticosteroid injections before diagnosis was 2.6 for 7 patients. All 23 patients were treated with a combination of extensive tenosynovectomy and antibiotics. @*Results@#Of the 23 patients, 20 were available for the final follow-up (1, lost to follow-up; 1, transferred to another hospital; and 1, died from a comorbidity). The most common species was Mycobacterium intracellulare (70%), followed by Mycobacterium abscessus (10%). The frequency of involvement of the extensor/flexor tendon was similar to that of the wrist/finger. The mean number of surgical debridement operations was 2.2. The average duration of antibiotic administration was 9.8 months. At the last follow-up, 3 patients were symptom-free with full range of motion at the involved site, 1 patient complained of localized swelling or pain with full range of motion, 1 patient was found to have a recurrence of infection in a finger, and 15 complained of restricted joint motion. @*Conclusions@#The most common species noted in patients with nontuberculous mycobacterial tenosynovitis was M. intracellulare. Patients with only 1 finger involved showed good range of motion at the final follow-up. Most patients experienced delayed wound healing and adverse effects from drug therapy during treatment and limited joint motion at the final follow-up.
RESUMO
Methods@#The electronic databases MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched for relevant articles comparing the outcomes of SB-ACLR versus DB-ACLR that were published until November 2019. @*Results@#Seventeen biomechanical studies were included. The anterior laxity measured using the anterior drawer test showed significantly better results in DB-ACLR when compared with SB-ACLR. In addition, outcomes of the anterior tibial translation test under a simulated pivot shift presented with better results at low flexion and 30° in DB-ACLR, compared with SB-ACLR. However, there were no significant biomechanical differences between the groups in internal rotation. @*Conclusions@#The present study demonstrated that both techniques for ACLR are associated with restoration of normal knee kinematics. DB-ACLR is superior to SB-ACLR in terms of restoration of anteroposterior stability.However, which technique yields better improvement in internal rotation laxity, and internal rotation laxity under a simulated pivot shift at a specific angle, remains unclear.Level of evidence: This is a level II meta-analysis.
