For insight into medium-term results of ACL reconstruction, see the July 2005 article Clinical Outcome at a Minimum of Five Years After Reconstruction of the Anterior Cruciate Ligament, by Spindler et al., in the Long-term Consequences of ACL Injuries Subsection. For insight into the simplified kinematics (motion) of the ACL-reconstructed knee, a consequence of the single-unit (i.e. single-bundled if hamstring autograft, single-stranded if patellar-tendon autograft) nature of modern-day ACL grafts, see the the June 2004 article Abnormal Rotational Knee Motion During Running After Anterior Cruciate Ligament Reconstruction, by Tashman et al., in the Biomechanics, Knee Alignment, and Component Interdependency Subsection. Fixed tibial subluxation after successful anterior cruciate ligament reconstruction, Louis C Almekinders et al.; American Journal of Sports Medicine, Baltimore; May/Jun 2001, Vol 29/3, pages 280-283. Comments: This study discusses the biomechanical problems and consequent long-term concerns associated with tibial subluxation in the ACL-reconstructed knee. Although modern tendon-graft ACL-reconstruction methods are good for restoring the kinematics of the knee, the fact that a natural ACL has a multifascicular structure makes exact replication its function with a single-bundle graft infeasible. Development and evaluation of an activity-rating scale for disorders of the knee, Robert G. Marx; The American Journal of Sports Medicine, Baltimore; Mar/Apr 2001, Vol 29/2, p. 213. Comments: This article discusses a knee-function classification system, and includes points on planning and presentation of knee-patient questionnaires. Comparison of score evaluations and instrumented measurement after anterior-cruciate-ligament reconstruction, Ralph Hrubesch; The American Journal of Sports Medicine, Baltimore; Nov/Dec 2000, Vol 28/6, p. 850. Comments: Hrubesch et al. note the differences in how the various serviceability-rating scales that are commonly used when evaluating ACL-reconstructed knees record parameters indicative of knee functioning, and delve into the issues underlying the need for inter-rating-system universality and consistency. The reader is assumed to have an understanding of some aspects of statistics. Rigorous statistical reliability, validity, and responsiveness testing of the Cincinnati knee rating system in 350 subjects with uninjured, injured, or anterior-cruciate-ligament-deficient knees, Sue D. Barber-Westin; The American Journal of Sports Medicine, Baltimore; Jul/Aug 1999, Vol 27/4, p. 402. Comments: This detailed article is a thorough and carefully-done study of the Cincinnati knee-serviceability scoring system. Some background in introductory statistics is assumed.
