This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Introduction The recovery of periarticular strength is a major criterion in return-to-play testing. The rationale of the study was to assess the impact of the delay of surgery (∆ between injury and surgery) on knee extensor and knee flexor strength of anterior cruciate ligament (ACL)-deficient patients six months after reconstruction. Materials and methods In a retrospective cohort study, all patients with ACL ruptures between 03/2015 and 12/2019 were analyzed. Inclusion criteria were isolated ACL rupture without any associated lesions undergoing a reconstruction using ipsilateral hamstring tendon autograft and adherence to isokinetic strength testing before and at 5-7 months postoperatively. These patients were then clustered into three groups: EARLY reconstruction (∆ 42 days), DELAYED reconstruction (∆42-180d), and CHRONIC (∆ 180d). Knee extensor and flexor strength of the ipsi- and contralateral leg were analyzed by concentric isokinetic measurement (60°/s). Primary outcomes were the maximal knee extension and flexion torque, hamstrings-to-quadriceps ratio (H/Q) ratio), and the corresponding limb symmetry indices. Results n = 444 patients met the inclusion criteria. From EARLY to DELAYED to CHRONIC, a progressive reduction in postoperative strength performance was observed in knee extension (1.65 ± 0.45 to 1.62 ± 0.52 to 1.51 ± 0.5 Nm/kg resp.) and flexion (1.22 ± 0.29 to 1.18 ± 0.3 to 1.13 ± 0.31 Nm/kg resp.) strength on the ACL reconstructed leg. This general loss in periarticular strength was already apparent in the preoperative performance even on the healthy side. When controlling for the preoperative performance using ANCOVA analysis, EARLY performed significantly better than DELAYED (extension p = 0.001, flexion p = .02) and CHRONIC (extension p = 0.005, flexion p 0.001). Also, there were significantly higher values for H/Q ratio in the injured leg across all groups where the H/Q ratio increased from EARLY to CHRONIC and from pre- to postoperative values.brbrConclusions
Download or read book Estimating Muscle Forces and Joint Contact Forces in the Anterior Cruciate Ligament Deficient Knee written by Emily Gardinier and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the estimated 200,000 individuals who sustain anterior cruciate ligament (ACL) injuries annually in the U.S. experience characteristic knee instability with daily activities (.noncopers.). The risk for developing knee osteoarthritis (OA) increases after injury, and within 20 years half of ACL-injured patients will have radiographic OA, significant pain and functional limitation. The noncoper gait strategy has been described in terms of aberrant movement and altered muscle activity, but neither muscle forces nor joint loads have been investigated. Further characterization of their neuromuscular strategy and knee joint loading will ultimately expand our understanding of the onset and progression of knee OA after ACL injury. Therefore, the first aim of this work was to identify the well-described decreased injured limb peak extensor moment in a group of noncopers and to identify the muscle force adaptation which drove that gait asymmetry. We used an EMG-driven modeling approach to partition flexor and extensor group forces during normal walking. We found that noncopers accomplished the decreased peak moment with decreased muscle force from both flexor and extensor muscle groups. This strategy may be explained by muscle weakness which frequently accompanies ACL injury, or by apprehension, low confidence and fear of further injury. The second aim of this work was to determine whether medial and lateral joint contact forces are altered acutely after ACL rupture. Medial and lateral compartment loads were calculated using muscle forces obtained from EMG-driven modeling. Noncopers unloaded their injured knees. This adaptation may cause cartilage deconditioning, resulting in an increased potential for cartilage insult with the resumption of normal or excessive loading. The lower muscle force in the injured limb of these patients affirms the existence of neuromuscular asymmetries following ACL injury. The loading analyses provide a basis from which to compare longitudinal changes in knee joint loading.

Download or read book The Patella written by Giles R. Scuderi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems of the patellofemoral joint remain a challenge to the orthopaedic surgeon. In spite of many articles in scientific journals, an outstanding monograph, and several excellent textbook chapters, the patella is still an enigma in many respects. The etiology of patellar pain is controversial, and there is no completely satisfying explanation for its cause or its relationship to chondromalacia. Curiously, neither the widespread use of arthroscopy nor the advent of newer diagnostic tests such as CT scanning and magnetic resonance imaging have cast much light. Without a better understanding of why patellar disorders occur it is not surprising that there is no consensus on how to fix them. Arthros copy has contributed little except to the patient's psyche. The currently most popular surgical treatment for recurrent dislocation of the patella was first described 50 years ago. One concrete advance, albeit a small one, is a better understanding of the role of anatomical abnormalities and patellofemoral dysplasia in patellar instabilities. It gives me great pleasure that many of the contributors are, like Dr.
