Event Description
This report is being filed after the review of the following journal article: abdul g.Dudhniwala et al, 2012, ¿lateral meniscal tear resulting from the femoral cross-pin used for hamstring graft fixation in anterior cruciate ligament reconstruction¿, the knee volume 19 number 6 pages 951-952, united kingdom.The study emphasized that in using cross-pin system there is known incidence of breakage.The study recommends a low threshold to investigate with a mri scan any new symptoms following acl reconstruction with cross pin fixation.The patients evaluated on course of this study: a (b)(6) man presented with history of injury to his right knee whilst playing football resulting in a complete acl tear, he underwent acl reconstruction with a four-strand hamstring tendon autograft.The graft was fixed on the femur using two bioabsorbable cross-pins (rigidfix®, depuy mitek inc.) and on the tibia with an intrafix screw (depuy mitek inc) and sheath.The article describes the following procedure: diagnostic arthroscopy performed during this procedure did not reveal any other meniscal.Chondral or ligament injury.No untoward events were encountered during the operation and satisfactory graft fixation and knee stability were achieved.Following this he underwent routine acl rehabilitation under the supervision of physiotherapists, achieving full knee range of motion and knee stability on clinical examination.He was discharged from clinical follow up and started participation in sporting activities within 9 months of acl reconstruction.The devices involved were: two bioabsorbable cross-pins (rigidfix®, depuy mitek inc.) and on the tibia with an intrafix screw (depuy mitek inc).Complications mentioned in the case report were: the patient presented 13 months following the acl reconstruction with symptoms of knee pain, locking and catching.He did not recall any specific injury to the knee which initiated these symptoms.On clinical examination of the knee there was a mild joint effusion, tenderness over the lateral joint line and a stable acl on pivot shift and lachman test.To investigate these new symptoms an mri scan of the knee was performed which showed lateral end of the distal femoral cross-pin abutting the lateral meniscus (fig.1), tear in the lateral meniscus, and breakage of the distal cross pin at the bone-graft junction.There was a minimal joint effusion and an intact acl graft without any evidence of graft impingement, tunnel osteolysis or cyclops lesion.He underwent a knee arthroscopy which revealed the broken distal cross-pin which was pistoning in its tunnel and was in contact with the lateral meniscus (fig.2).There was a tear in the lateral meniscus at this site of abutment with cross pin and inflammation of the surrounding synovium.The acl graft was intact and functional.The broken cross-pin was removed, and the lateral meniscus was repaired with meniscal sutures.Postoperatively his symptoms resolved, and he returned to his activities after rehabilitation.
