Introduction: Stair ascent and descent are physically demanding tasks requiring higher functional ability of the lower extremity muscles and joint range of motion than level walking, and are associated with patient satisfaction after total knee arthroplasty (TKA). This study aimed to investigate stair ascent and descent ability after cruciate-retaining (CR)-TKA using the patient-reported outcomes, and to examine the role of knee sagittal stability and handgrip strength in postoperative stair ascent and descent ability.
Materials And Methods: This study included 84 female patients who underwent primary unilateral CR-TKA for knee osteoarthritis at our institute between April 2015 and February 2019.
Article Synopsis
- The study investigates how effectively MRI can detect meniscal ramp lesions in the knee when positioned at 120° flexion versus near extension, noting that traditional MRI methods have low sensitivity for these types of injuries.* -
- Researchers analyzed data from 154 patients undergoing ACL reconstruction and found that MRI in the flexed position had significantly higher sensitivity (91.9% vs. 69.4%) and specificity (94.6% vs. 77.2%) in identifying these lesions.* -
- The findings suggest that performing MRI scans with the knee flexed improves diagnostic accuracy for ramp lesions, which is crucial for proper preoperative planning in ACL reconstructive surgery.*
Purpose: Medial meniscus posterior root tears (MMPRT) are a risk factor for knee osteoarthritis. The predominant treatment for MMPRT is transtibial pullout repair, and loop suture remains the gold standard procedure. This study aimed to investigate the structural properties of the meniscus-suture-tibia (MST) complex after loop stitch using ultra-high molecular weight polyethylene (UHMWPE) suture tape of different thicknesses.

- A study analyzed the forearms of 36 patients who underwent surgery for distal radial fractures using an anterior locking plate via the trans-flexor carpi radialis approach.
- Results showed that after the placement of the plate, the median nerve was positioned more radially (towards the thumb side) than on the healthy side, and exhibited signs of hypertrophy and flattening.
- The findings suggest that confirming the radial positioning of the median nerve with ultrasonography before removing the plate is essential to avoid potential nerve injuries.
