Purpose: Patient-reported outcome measures (PROMs) are important measures of success after total knee arthroplasty (TKA) and being able to predict their improvements could enhance preoperative decision-making. Our study aims to compare the predictive performance of machine learning (ML) algorithms and preoperative PROM thresholds in predicting minimal clinically important difference (MCID) attainment at 2 years after TKA.
Methods: Prospectively collected data of 2840 primary TKA performed between 2008 and 2018 was extracted from our joint replacement registry and split into a training set (80%) and test set (20%).
Background: Diabetes is one of the most common comorbidities in patients undergoing total knee arthroplasty (TKA) for osteoarthritis. However, the evidence remains unclear on how it affects patient-reported outcome measures after TKA.
Methods: We reviewed prospectively collected data of 2840 patients who underwent primary unilateral TKA between 2008 and 2018, of which 716 (25.
The current review aims to compare the outcomes of anterior cruciate ligament (ACL) reconstruction in the female population after patellar-tendon-bone and hamstring grafts. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All original randomized controlled trials and prospective cohort studies that compared clinical outcomes after female ACL reconstruction using hamstring versus patellar-tendon-bone grafts were included.

It has been shown to have comparable outcomes with open stabilization. This usually involves the use of 2 portals anteriorly: one anterosuperior accessory portal and another anteroinferior working portal.

This study aims to determine and predict if computed tomography (CT) scans alone can be performed without risking oversight of substantial injuries found on follow-up magnetic resonance imaging (MRI).
Methods: This is a retrospective cohort study of 63 blunt trauma patients with a Glasgow Coma Scale of < 8.
Polyaxial screw head dislocation in the absence of a manufacture defect is extremely rare and represents a biomechanical overload of the screw, leading to early failure. A 58-year-old gentleman underwent instrumented fusion using polyaxial pedicle screws-titanium rod construct with interbody cage for spondylolytic spondylolisthesis at the L5/S1 level. He attempted to bend forward ten days after the surgery which resulted in a dislocation of the right S1 polyaxial screw head from the screw shank with recurrence of symptoms.

However, the influence of patient sex on the outcome after ACL reconstruction remains unclear, with some authors reporting inferior outcomes in females and others noting no significant difference.
Purpose: To provide a comprehensive systematic review and meta-analysis to examine the possible association between patient sex and the subjective and objective outcomes after ACL reconstruction.
