Background:Loss of motion (LOM) remains a common complication after anterior cruciate ligament (ACL) reconstruction and can be detrimental to patient outcomes after surgery. LOM is multifactorial, but nonsurgical and surgical solutions to this complex problem are available. A paucity of quality data exists evaluating clinical outcomes after the surgical treatment of patients with LOM after ACL reconstruction.Hypothesis:Patients undergoing surgical lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction will exhibit decreased function, lower outcome scores, and delayed time of release to play when compared with matched controls without LOM.Study Design:Cohort study; Level of evidence, 3Methods:A database of 1572 patients undergoing ACL reconstruction was sampled from 2013 to 2017 to identify a total of 58 patients (LOM group [n = 29] vs matched control group [n = 29]). Group comparisons were examined for patients requiring a second surgical procedure for LOM versus matched controls after ACL reconstruction for differences in surgical timing, self-reported International Knee Disability Committee scores, objective function at release to play, and subjective knee function at 2 years with the Single Assessment Numeric Evaluation. The risk of a type I error was set at α = .05 for all statistical analyses.Results:Patients who underwent lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction exhibited no differences in Single Assessment Numeric Evaluation knee function at 2 years when compared with matched controls (85.8 ± 14.9 vs 88.0 ± 10.8, P = .606). All patients met release-to-play criteria. Only International Knee Disability Committee scores ( P = .046) and single-legged hop testing ( P = .050) reached statistically significant differences, with higher scores in the control group. There was no difference in the time to release to play ( P = .034) or level of participation ( P = .180) between the control and surgical groups. Subjective function scores at 2 years were not significantly different between groups. Tourniquet time during the index ACL reconstruction was shorter in the control group ( P = .034).Conclusion:The findings of this study suggest that patients who undergo surgical treatment for LOM after ACL reconstruction can release to play at similar times but display relative deficits in single-legged-hop symmetry and lower self-reported function when compared with matched controls. Longer surgical times may increase the risk for LOM after ACL reconstruction.Registration:NCT03704376 (ClinicalTrials.gov identifier)

Introduction: Vascular injuries, although rare, can occur after total hip arthroplasty. this complication is potentially limb or lifethreatening. case report: We report on a patient who had an acute arterial thrombosis of an aortobifemoral bypass graft after revision total hip arthroplasty through an anterior approach. this occlusion occurred in the immediate postoperative period was recognized and treated effectively. conclusion: After thorough research review, only two instances of aortobifemoral bypass graft occlusion were found after total hip arthroplasty. this is the first case report of an arterial thrombosis of an aortobifemoral bypass graft in a total hip via an anterior (modified Hardinge) approach to the hip. It is also the first case report of a revision procedure causing thrombosis in this graft type. this paper illustrates the importance of vigilance of vascular complication in post-surgical total joint patients.
