Case:A 31-year-old US service member presented with a patellar tendon tear that was repaired acutely with 2 biocomposite suture anchors. He presented more than 2 years later with a stress fracture through a suture anchor drill hole and was treated with partially threaded screw fixation.Conclusion:Stress fracture through a suture anchor drill hole after patellar tendon repair is a previously unreported complication. Surgeons should have a high index of suspicion and low threshold to obtain advanced imaging in cases of unexplained pain after patellar tendon repair.
Anterior cruciate ligament (ACL) tears with concomitant cartilage injuries resulting in ACL reconstruction (ACLR) with cartilaginous procedures are common in the young, high-demand population. The purpose of this study was to report and characterize cartilage treatments performed at the time of index ACLR reconstruction and to determine if those treatments are associated with revision surgery (of any kind) in the 4-year follow-up. We performed a consecutive series of active duty service members in the Military Health System Data Repository with ACLR with and without concomitant cartilage procedures done at military facilities between October 2008 and September 2011. Patients were continuously enrolled with no history of knee surgeries for 2 years prior to primary ACLR. ACLR failure was defined as revision ACLR within 4 years following the primary ACLR. Of the 2,735 primary ACLRs included in the study, 5.3% (143/2,735) underwent isolated ACLR with a cartilage procedure. Of these patients, 23.07% (33/143) experienced ACLR failure within 4 years after ACLR with cartilage procedures, including 33.33% (11/33) undergoing revision ACLR. We found concomitant cartilage procedures at time of index ACLR to have the following rates of revision 35.59% (21/59) for microfracture, 14.63% (6/41) for chondroplasty, and 13.95% (6/43) for osteochondral grafts. The overall clinical failure rate of service members with ACLR plus concomitant cartilage procedure is 23.07% with minimum 4-year follow-up. Further research should be done to identify modifiable demographic and surgical factors associated with failure. This is a retrospective case-control study that reflects level of evidence III.
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.
