Purpose: To assess the relation between tendon migration, as measured by radiostereometric analysis, and patient-reported outcome measures (PROMs) after biceps tenodesis (BT); to determine the likelihood of achieving clinically significant outcomes (CSOs) after BT; and to identify factors that impact CSO achievement.
Methods: Patients undergoing arthroscopic suprapectoral or open subpectoral BT at a single, high-volume academic medical center were prospectively enrolled. A tantalum bead sutured to the tenodesis construct was used as a radiopaque marker.

Meniscal tearing can increase the contact pressure between the tibia and femur by causing gapping of torn meniscus tissue. The aim of this study was to quantify gapping behavior of radial and longitudinal tears and their impact on peak contact pressure and mean contact area. Twelve porcine knee joints underwent unicondylar, convertible osteotomy for exact tear application and consecutive suturing.

Background: Studies suggest that similar clinical results are achieved via arthroscopic and open biceps tenodesis (BT) techniques.
Purpose: To quantify the postoperative migration of the BT construct between arthroscopic suprapectoral BT (ASPBT) and open subpectoral BT (OSPBT) techniques via interference screw (IS) or single-suture suture anchor (SSSA) fixation using radiostereometric analysis.
Study Design: Cohort study; Level of evidence, 2.
A 53-year-old man undergoing painless colonoscopy for long-term diarrhea. After colonoscopy withdrawing to the sigmoid colon, a local perforation was found, about 3 cm in size, oval in shape. We used a two-channel endoscope and grip to pull the edges of the intestinal wall on both sides of the perforation site to close together, and then repair the 3 cm oval perforation of the colon through multiple ordinary titanium clips.

Postoperative anastomotic leaks are the most feared complications after gastric surgery. For diagnostics clinicians mostly rely on clinical symptoms such as fever and tachycardia, often developing as a result of an already fully developed, i.e.
