Background. Pragmatic review of outcomes for single stage revision ACL reconstruction performed in
a single center and the reasons for failure in primary surgery.
Material and methods. Retrospective study included 59 patients with revision ACL reconstruction done by one surgeon from 2007 to 2017.Clinical records, operative notes and x-rays were assessed to find the reasons of failure.
Results. The cause of failure was traumatic in 26 (44.1%) patients after primary reconstruction, incorrect tunnel position in 18(30.5%) and biological failure in 15 (25.4%). All ACL revisions were done using autografts; patellar tendon grafts in 33 patients (55.9%), ipsilateral hamstrings in 12 (20.3%), contralateral hamstrings in 9 (15.3%) and quadriceps tendons in 5 (8.5%). Twenty-one patients were contactable as regards postoperative functional outcome scores. There was an average 18 point improvement in Oxford knee score (OKS) post-operatively, 1.6 point improvement in Tegner scores and 30 point improvement in Lysholm scores. One patient (1.7%) developed septic arthritis, 4 (6.8%) had superficial infection, while 6 (10.2%) had residual instability after revision but did not have further surgery. There was lack of full extension in 4 (6.8%) patients. In BTB grafts, 2 (6.1%) patients sustained a post-traumatic patellar fracture.
Conclusions: 1. Good outcomes of single stage revision ACL reconstruction surgery are achievable as demonstrated in our cohort. 2. There is need for good quality research to identify whether BTB, hamstrings or quadriceps autografts are better for ACL Reconstruction.
A ring is traditionally worn as a symbol of love and affection or as decorative ornamental jewellery. However, rings are not without risk. The spectrum of danger can range from debilitating avulsion injuries to simple contact dermatitis. Unknown to many, an unusual rarity exists; previous authors have termed this entity 'embedded ring syndrome'. We sought to review the literature and collate evidence on the common features of this syndrome. A literature review was performed on cases reported from 1947 to 2017 accessed through the healthcare database advanced search (HDAS). A total of 28 cases were analysed for demographics, symptomatology and operative techniques. Overall, 64.3% were females, and 50% had a psychiatric comorbidity. There was a causative event preceding the injury in 35.7% of cases; 71.4% had a reduced range of movement or reported a stiff finger and 32.1% had reduced sensation. The majority of patients underwent ring removal and primary closure, without documentation as to whether neurovascular bundles and tendons were visualised. Embedded ring injuries are rare. Consequently, information is sparsely available regarding its natural history and management. The hand surgeon's approach requires an understanding that the chronicity of these injuries can have a significant traumatic impact on the structures of the finger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
