“… 4 , 5 However, CT-constructed bone models may also be used for MBM, which makes it possible to evaluate in vivo joint kinematics without markers. 6 - 8 Analysis with MBRSA though is time consuming as it requires manual user interaction. A second method for analysis of stereoradiographs is by use of digitally reconstructed radiographs (DRR).…”

ObjectivesTo validate the precision of digitally reconstructed radiograph (DRR) radiostereometric analysis (RSA) and the model-based method (MBM) RSA with respect to benchmark marker-based (MM) RSA for evaluation of kinematics in the native hip joint.MethodsSeven human cadaveric hemipelves were CT scanned and bone models were segmented. Tantalum beads were placed in the pelvis and proximal femoral bone. RSA recordings of the hips were performed during flexion, adduction and internal rotation. Stereoradiographic recordings were all analyzed with DRR, MBM and MM. Migration results for the MBM and DRR with respect to MM were compared. Precision was assessed as systematic bias (mean difference) and random variation (Pitman’s test for equal variance).ResultsA total of 288 dynamic RSA images were analyzed. Systematic bias for DRR and MBM with respect to MM in translations (p < 0.018 mm) and rotations (p < 0.009°) were approximately 0. Pitman’s test showed lower random variation in all degrees of freedom for DRR compared with MBM (p < 0.001).ConclusionSystematic error was approximately 0 for both DRR or MBM. However, precision of DRR was statistically significantly better than MBM. Since DRR does not require marker insertion it can be used for investigation of preoperative hip kinematics in comparison with the postoperative results after joint preserving hip surgery.

“…La utilización de este refuerzo en cirugías de revisión del LCA también mejora la estabilidad de la rodilla (106) . Sin embargo, Anderson et al (108) y Roth et al (109) no encontraron ningún beneficio al añadir este refuerzo lateral, al igual que otro estudio actual (110) . Sonnery-Cottet et al (38) , en un estudio clínico prospectivo con 2 años de evolución, evidenciaron mejoría en los pacientes con esta plastia de refuerzo lateral tanto en estabilidad como en fallos y complicaciones.…”

“… 84 Because of its potential role in preventing translation and internal rotation near extension, it may be a factor behind a high grade of pivot shift and a failure to restore normal kinematics in some individuals undergoing ACLR only; a majority of biomechanical, clinical, and cadaver studies support this theory. 82 83 84 85 86 …”

Sports medicine physicians have a keen clinical and research interest in the anterior cruciate ligament (ACL). The biomechanical, biologic, and clinical data researchers generate, help drive injury management and prevention practices globally. The current concepts in ACL injury and surgery are being shaped by technological advances, expansion in basic science research, resurging interest in ACL preservation, and expanding efforts regarding injury prevention. As new methods are being developed in this field, the primary goal of safely improving patient outcomes will be a unifying principle. With this review, we provide an overview of topics currently in controversy or debate, and we identify paradigm shifts in the understanding, management, and prevention of ACL tears.
