Minimal changes in patella height after aseptic revision from unicompartmental to total knee arthroplasty.

Introduction: If revision of a unicompartmental knee arthroplasty (UKA) is required, converting it to a total knee arthroplasty (TKA) remains the favored approach. However, worse functional outcomes after revision from UKA to TKA are reported compared to primary TKAs. One potential driver may be a decline in patella height, limiting knee flexion, and increasing patellofemoral stress.

Medium-term outcomes after magnetic sphincter augmentation vs. fundoplication for reflux disease due to hiatal hernia: a propensity-score matched comparison in 282 patients.

Background: An increasing number of reflux patients opt for magnetic sphincter augmentation (MSA) instead of fundoplication. However, few studies compare the medium-term efficacy and safety of the procedures.

Methods: We conducted a retrospective single-center analysis of consecutive MSA and Nissen fundoplication cases between 01/2015 and 06/2020.

Long-term results after laparoscopic revision fundoplication: a retrospective, single-center analysis in 194 patients with recurrent hiatal hernia.

Background: After laparoscopic fundoplication, 10-20% of patients experience symptom recurrence-often due to resurgence of the hiatal hernia. The standard surgical treatment for such cases remains laparoscopic revision fundoplication. However, there is little data on the time frame and anatomic patterns of failed fundoplications.
