Woo, JOS, 2006) Meta-analyses evaluating success rates of ACL recon: 69%-95% (Freedman AJSM 2003) ESSKA approved teaching center ACL is the primary restraint to tibial anterior translation that is normally accompanied by a couple tibial rotation AM bundle is more important resisting AP translation. for PL bundle is tight near extension and plays a role in tibial internal rotation KSSTA, April 2012 MENISCUS & ACLR • Cross all rehab protocols and assess time frames and criteria of each associated injury • Respect timeframe of each repair/reconstruction technique/tissue healing. Flexion may be limited to 90 degrees - 3/4 weeks - in repairs of the posterior horn • Criteria based progress – accept a delay on ROM, weightbearing, strenghtening exercises, proprioception, neuromuscular reeducation if needed • Take advantage of time window for meniscal repair in the setting of concomitant injuries (ACLR) NO CONSENSUS IN LITERATURE ABOUT TECHNIQUE & RETURN TO SPORT 3D kinematic analysis to evaluate the functional levels of the knee, it has been found that in the ACL-deficient knee there is anterior tibial translation and excessive tibial rotation during everyday activities. ACLR is successful in restoring these functions when lowdemanding activities such as walking are performed. During high-demanding activities, ACLR seems to fail to restore excessive tibial rotation, which may be the cause of further degeneration in the medial compartment even after ACLR. PREVENTION GOALS OF ACLR “YOU CAN MAKE A DIFFERENCE!” • Absence of pain, swelling • Restoration of ROM and muscle strength • Restoration of proprioception • Return to work • Return to sport activity • Return to sports at the same level • Prevention of degenerative OA • Restoration of normal knee kinematics Lars Engebretsen, Editorial, KSSTA, May 2009 “The soccer players do not appear to spend much time on preventive work You need to bring the coaching staff & players to your side early (with the youngsters) The using the available science will reduce the injuries and post-injury problems” Engebretsen et al , AJSM, 2008 Hurd et al, AJSM, 2008 Soligard, et al, BMJ, 2008 RISK FACTORS Does bone morphology play a role in laxity & rotation? M. Fernandes, A. Monteiro, N. Sevivas H. Pereira and Espregueira-Mendes (in press) “Bone morphology of the external femoral & tibial condyles are the trochlea of the ACL” Conclusion: Methods 36 patients 29 ♂ and 7♀, with recent rupture of ACL were compared with other 36 subjects 29 ♂ and 7 ♀, without any knee pathology. We measured in the femur: the diameter of the shaft, height and anteroposterior diameter of the external condyle, the flattened lower limit of the epiphysis and the distance of the latter to the anterior and posterior cortical diaphysis (yz and xw). In the tibia, we measured the AP diameter of the tibial plateau and tibial slope. •There are significant differences in bone morphology Results ♂ with non traumatic rupture of the ACL (compared with healthy population) we found: A bigger height and AP length of the external condyle (yz and xw). A smaller AP diameter of the tibial plateau. •Condyle size is a risk factor for ACL injury – may influence knee Kinematics • Significant differences in bone morphology between ACL-injured and non-injured subjects •Notch width measures on MRI and arthroscopically have no correlation The results suggest that the parameters above can be risk factors in the ACL rupture. DIAGNOSIS HEMARTROSIS : 82% ACL Clinical evaluation X-Ray MRI Arthrometer/PKTD Arthroscopy CLINICAL EVALUATION “..THE DIAGNOSIS OF AN ACL RUPTURE IS DONE BY HAND..” MRI Evaluate associated lesions Meniscus Cartilage Bone bruise Other Ligaments Measure instability & evalute partial ruptures Is a diagnosis of partial or even total ACL rupture enough to indicate surgery in 2013 (PL in high level football players?) How to be sure about the functioning of the remaining bundle? Can we correctly measure AP translation & rotation? Can we control rotation without knowing the value of normal pattern? Do we know how much AP translation, rotation or both combined causes instability (“cut point”)? “A simple clinically applicable tool, similar to KT 1000 arthrometer, that could be used to quantify laxity and rotation needs to be developed” J. Irrgang, J. Bost & F. Fu Letter of AJSM 2009 “ Both instrumented laxity and MRI need to be used in combination with proper clinical evaluation to possibly acquire a greater diagnosis value.” D.
