Article Synopsis
- - This study explored the relationship between MRI findings and actual tissue degeneration in the anterior cruciate ligament (ACL) of patients with knee osteoarthritis (OA), aiming to create a new grading system based on MRI results matching histological analysis.
- - Researchers analyzed 106 ACL specimens from patients who had knee surgery, calculating the signal intensity of the ACL compared to muscle on MRI to assess degeneration.
- - The findings showed a strong correlation between MRI signal intensity ratios and the degree of collagen degeneration, leading to a new grading system that classifies ACL degeneration into three levels, potentially improving diagnosis and treatment of knee OA.
Article Synopsis
- The study aimed to explore the link between neuropathic pain (NP) and radiological findings in knee osteoarthritis (OA) patients undergoing surgery.
- Out of 197 patients, 34 were identified with possible NP, exhibiting higher central sensitization and worse symptoms compared to those with unlikely NP.
- No specific radiological indicators were found to predict NP in knee OA; however, patients with possible NP tended to have more severe pain and reduced knee function.
Article Synopsis
- The study investigated how the surgeon's experience affects the reproducibility of joint gap measurements during manual stress in robotic-assisted total knee arthroplasty (TKA) and whether the distraction force remains consistent throughout the range of motion (ROM).
- Results showed that an experienced surgeon achieved significantly larger joint gaps compared to an inexperienced surgeon, especially during specific flexion angles.
- There was a correlation between the gap measurement differences and preoperative hip-knee-ankle (HKA) angles, suggesting that the surgical technique and patient anatomy both influence joint stability outcomes.
Background: The purpose of this study was to investigate axial load resistance of the tibia depending on the thickness of tibial tuberosity osteotomy in medial open-wedge distal tuberosity proximal tibial osteotomy (OWDTO). The hypothesis is that a thin tibial tuberosity osteotomy shows high axial load resistance of the tibia.
Methods: The OWDTO model was constructed from imitation bones of the tibia.
Background: The function of the anterior cruciate ligament (ACL) in osteoarthritis (OA) of the knee remains to be elucidated. The purpose of this study is to evaluate histological changes of the ACL in end-stage knee OA and to clarify the relationship between histological changes in the ACL and knee function.
Hypothesis: The hypothesis in this study was that ACL degeneration in knee OA is associated with decreased knee function.
Article Synopsis
- - The study aimed to determine if the medial proximal tibial angle (MPTA) at the posterior tibial plateau can indicate the pre-arthritic MPTA in knees with advanced osteoarthritis (OA) that still have an intact anterior cruciate ligament (ACL).
- - In the analysis of 100 OA knees, researchers examined the hip-knee-ankle (HKA) angles and MPTAs using computed radiography and computed tomography, discovering variations in MPTA measurements across different regions of the tibial plateau.
- - The findings suggested that the MPTA at the posterior tibial plateau is reflective of the pre-arthritic MPTA in ACL-intact advanced OA knees, with significant correlations
