Endoprosthesis Register: Prospective Implant, Perioperative, and Outcomes Data for Hip and Knee Arthroplasty
Single-centre prospective registry capturing implant data, perioperative variables, and clinical outcomes for primary and revision hip and knee arthroplasty. The dataset anchors all other arthroplasty studies of the group.
Lead: Dimitar Tenev, MD
Ongoing 2026-present
PHQ-9 Depression Scores in Knee Arthroplasty Patients: A Prospective Observational Study
Prospective observational study of depressive symptom trajectories, measured with the PHQ-9, in patients undergoing primary knee arthroplasty. Pre- and post-operative time points capture the mental-health course alongside the standard surgical outcome set.
Lead: Georgi Enev, MD

PHQ-9 Depression Scores in Hip Arthroplasty Patients: A Prospective Observational Study
Prospective observational study of depressive symptom trajectories, measured with the PHQ-9, in patients undergoing primary hip arthroplasty. Companion to the knee-arthroplasty PHQ-9 study; identical instrument, distinct cohort.
Lead: Georgi Enev, MD
Ongoing 2026-present
Functional Capacity (FUNCAP27 Scale) in Knee Arthroplasty Patients: A Prospective Case Series
Prospective case series measuring functional capacity with the 27-item FUNCAP scale across the perioperative course of primary knee arthroplasty. Pre- and post-operative scoring quantifies the patient-reported recovery curve.
