– Discussion: – see Arthrex, Mitek, Linvatec, Smith-Nephew – in choosing a fixation technqiue consider the need for the following: – circumferential (360 deg) healing of graft against tunnel wall (interference screws do not permit this); – bioabsorbable material … Read more
– Discussion: – femoral tunnel – tibial tunnel: – isometric placement of ACL refers to the concept that a full range of knee can be achieved w/o causing long-term ligament deformation; – isometry can not exist because, during ROM, there is no one point on femur that … Read more
– Discussion: – anatomy of ACL; – ACL biomechanics; – graft tunnel sites / isometry: – hamstring ACL reconstruction is an alternative to bone patellar bone graft fixation; – size and strength of graft: – double looped hamstring graft is more than twice as … Read more
– See: Achilles Tendonitis – Discussion: – ruptures typically occur after age 30, more often in people beyond middle age; – rupture at musculous tendinous junction occurs most often in young people, but ruptures near the calcaneus also occur; – inciting event may be related to … Read more
