Significant effect of the posterior tibial slope and medial/lateral ligament balance on knee flexion in total knee arthroplasty
TLDR
The postoperative flexion angle is affected by multiple factors, especially in cruciate-retaining-type TKAs, and it is important to pay attention not only to the posterior tibial slope, but also to the flexion medial/lateral ligament balance during surgery.
Added Value of Preoperative Computed Tomography for Determining Cartilage Degeneration in Patients With Osteochondral Lesions of the Talar Dome
Background: Osteochondral lesions of the talar dome (OLTs) involve the articular cartilage and subchondral bone. The subchondral bone plate (SBP) plays a crucial role in cartilage metabolism, and
Evaluation of articular cartilage following rotational acetabular osteotomy for hip dysplasia using T2 mapping MRI
TLDR
This study suggests that biomechanical and anatomical changes could apparently cause decreased T2 values 1–2 years postoperatively compared with those preoperatively, and that preoperative T2values of the acetabulum can be prognostic factors for the clinical results of RAO.
Evaluation of Articular Cartilage Injury Using Computed Tomography With Axial Traction in the Ankle Joint
TLDR
CT with axial traction produced acceptable levels of sensitivity and specificity for the evaluation of articular cartilage injuries, in addition to the assessment of subchondral bone.
Factors affecting the potential for posterior bony impingement after total hip arthroplasty
TLDR
Posterior bony impingement after THA is more likely in patients with a wider ischium and a narrow ischiofemoral space, and a high femoral offset and posterior pelvic tilt are also risk factors for this type of impingements.
Relationship Between Bone Marrow Lesions on MRI and Cartilage Degeneration in Osteochondral Lesions of the Talar Dome
TLDR
Investigating the relationship between the BML and cartilage degeneration in OLT revealed that a large area of BML on MRI exhibited low degeneration of cartilage of the osteochondral fragment, while a small area ofBML indicated sclerosis of the subchondral bone with severe degenerationof cartilage.
Local administration of WP9QY (W9) peptide promotes bone formation in a rat femur delayed-union model
TLDR
Results reveal that W9 has an effect on fractures of promoting healing and could be applied as a fracture treatment.
Magnetic Targeted Delivery of Induced Pluripotent Stem Cells Promotes Articular Cartilage Repair
TLDR
The magnetic delivery system proved useful and safe for cartilage repair using iPS cells and maintained pluripotency, and the histologic grading score was significantly better in the treatment group compared to the control group.
Outcome of autologous bone grafting with preservation of articular cartilage to treat osteochondral lesions of the talus with large associated subchondral cysts
TLDR
Autologous bone grafting with fixation of chondral fragments preserves the original cartilage in the short term, and could be considered in the treatment for adult patients with symptomatic osteochondral defect and subchondral cysts.
