This report is being filed after the review of the following journal article: kee-byung lee, et al , 2010 "delayed intra-articular migration of the intrafix outer sheath after anterior cruciate ligament reconstruction: a case report" elsevier b.V.The knee 18, page no-347-349, south korea.The study emphasizes on the observation of the delay of intra-articular migration of the intrafix outer sheath after anterior cruciate ligament reconstruction.The patients evaluated on course of this study: a (b)(6)-year-old female with a 6-month history of left knee pain after a twisting injury was taken as a subject.Physical examination revealed positive lachman test, tenderness at the lateral joint line and mild effusion.Magnetic resonance imaging (mri) revealed an acl discontinuity and a tear of the discoid lateral meniscus.Acl reconstruction was performed.At 5 months after surgery, the patient experienced a sudden catching sensation and a slight pain without any obvious twisting or trauma.At 6 months after surgery, extension deficit was 20°.At arthroscopy, intra-articular migration of the outer sheath from the tibial tunnel and reactive synovitis were observed.The article describes the following procedure: acl reconstruction was performed with an 8.5-mm tibial allograft tendon.Partial menisectomy and arthroscopy was also performed.The devices involved were: the graft was secured with a bioabsorbable rigid fix cross pins (depuy mitek, raynham,ma) on the femoral side and non-absorbable intrafix (dupey mitek, westwood, ma) with a post-tie staple on the tibial side.Complications mentioned in the article were: 5 months after surgery, the patient noted a sudden catching sensation and a slight pain with swelling in her operated knee with no obvious twisting or trauma.Mild effusion.Lateral joint line tenderness.Remnant lateral meniscal tear.Reactive synovitis.
