Vidyadhar V Upasani,Dylan G Kluck,Christine L Farnsworth et al.
Vidyadhar V Upasani et al.
Cobalt chromium (CoCr) and titanium (Ti) alloys are popular spinal rod choices due to biocompatibility, less imaging artifact than stainless steel, and greater corrosion resistance. This study assesses the mechanical behavior in bending of ...
Acute Prolonged Hamstrings Vibration Reduces Limb Stiffness Following Anterior Cruciate Ligament Reconstruction During a Single-Limb Drop-Jump Task [0.03%]
股四头肌振动降低前交叉韧带重建术后单腿跳任务中的下肢刚度
Timothy Lowe,Hao-Yuan Hsiao,Xuanliang Neil Dong et al.
Timothy Lowe et al.
Impaired quadriceps function influences lower limb biomechanics following anterior cruciate ligament reconstruction (ACLR). This often results in stiff limb loading which leads to the development of knee osteoarthritis. Greater hamstrings/q...

Vahid Danesh,Paul Arauz,Maede Boroji et al.
Vahid Danesh et al.
Pelvic bone tumor resections remain significantly challenging due to complex three-dimensional anatomy and limited surgical visualization. While accurate, current navigation systems and patient-specific instruments present limitations, incl...
Patellofemoral Cartilage Changes Are Not Associated With Quadriceps Metrics After ACLR With Patellar Tendon Autografts [0.03%]
前交叉韧带移植术后股四头肌力量与髌骨软骨变化无关
McKenzie S White,Steven A Garcia,Yuxi Pang et al.
McKenzie S White et al.
Quadriceps dysfunction (e.g., weakness or atrophy) is often implicated in the increased prevalence of posttraumatic osteoarthritis (PTOA) following anterior cruciate ligament reconstruction (ACLR). However, the relationship between quadrice...
Peak Vertical Ground Reaction Force Modifies Gait Biomechanics Bilaterally Following ACL Reconstruction: A Randomized Experiment [0.03%]
前交叉韧带重建后峰值垂直地面反作用力修改步态生物力学的随机实验
Elizabeth Bjornsen,Alyssa Evans-Pickett,Hope Davis-Wilson et al.
Elizabeth Bjornsen et al.
Vertical ground reaction force (vGRF) is a promising target for modifying aberrant gait biomechanics in individuals post-anterior cruciate ligament reconstruction (ACLR). However, an adequate sample size and arandomized, mechanistic study i...
Aberrant Gait Biomechanics Linked to Cartilage Changes After ACL Reconstruction in Those With High Body Mass Index [0.03%]
身体质量指数较高的患者前交叉韧带重建后的步态生物力学异常与软骨变化有关
Hyunwook Lee,Ashley N Buck,Cortney Armitano-Lago et al.
Hyunwook Lee et al.
A history of anterior cruciate ligament reconstruction (ACLR) and high body mass index (BMI) are strong risk factors for incident knee osteoarthritis. Limited research has evaluated the interaction between ACLR and high BMI on limb-level lo...
