Background: A robotic arm-assisted and a computed tomography (CT)- based navigation system have been reported to improve the accuracy of component positioning in total hip arthroplasty (THA). However, no study has compared robotic arm-assisted THA (rTHA) to CT-based navigated THA (nTHA) concerning accuracy of cup placement and acetabular fractures using the direct anterior approach (DAA). This study aimed to compare the accuracy of cup placement and the presence of intraoperative acetabular fractures between rTHA and nTHA using DAA in the supine position.

No study has compared these two procedures matching surgical approach and patient background. This study aimed to clarify the differences between SimBTHA using direct anterior approach (SimBTHA-DAA) and StaBTHA using the direct anterior approach (StaBTHA-DAA).

- A case study discusses a rare use of knotless suture anchors for treating patellar tendon ruptures following total knee arthroplasty (TKA) in an 82-year-old female who experienced a fall.
- The patient sustained the injury 8 weeks post-surgery, prompting a surgical repair using a knotless suture anchor and a twist-in knotless anchor with flat-braided suture.
- The study emphasizes the importance of addressing complications from TKA and suggests that this surgical method is a safe and effective option for repairing such injuries.
Article Synopsis
- The study evaluates the effectiveness of the iASSIST accelerometer-based navigation system in improving alignment accuracy during total knee arthroplasty (TKA) compared to conventional surgical methods using 3D imaging.
- A total of 83 knees were analyzed, with 42 using the iASSIST system and 41 using traditional guides, and results showed better alignment within 3° of neutral in both coronal and sagittal planes for the iA group.
- The findings concluded that iASSIST significantly improves femoral alignment during TKA, although there were no notable differences in clinical outcomes or patient reports at the 6-month check-up.
Ossification of spinal ligament is characterized by heterotopic bone formation in the spinal ligaments that are normally composed of fibrous tissues. The pathogenesis of ossification of spinal ligament has been suggested to be associated with osteogenic differentiation of the spinal ligament cells. In order to address this hypothesis, cells derived from human spinal ligament were investigated for their osteogenic potential by the treatment of dexamethasone in vitro.

- - Articular cartilage has a limited ability to heal itself, often resulting in tissue that is more fibrocartilage than the desired hyaline cartilage, leading to eventual degeneration of the articular surface.
- - A study investigated the impact of basic fibroblast growth factor (bFGF) on healing full-thickness cartilage defects in rabbits, using varying concentrations of bFGF mixed with collagen gel.
- - Results showed that treating defects with 100 ng of bFGF significantly enhanced cartilage repair compared to untreated defects, with improvements observed up to 50 weeks post-operation, indicating that bFGF could be a key player in cartilage repair strategies.
