Brief Summary

This prospective observational study aims to collect and analyse data on functional outcomes, quality of life indicators, and costs in patients undergoing primary total knee arthroplasty (knee replacement) surgery.

Conditions

Knee Arthropathy

Keywords

knee arthroplasty; knee replacement; quality of life; functional outcomes; costs; cost-utility analysis

Outcome Measures

Primary Outcomes (3)

• Change in cost-utility of the primary total knee arthroplasty

  As part of the cost-utility analysis (CUA), the Average Cost-Utility Ratio (ACUR) will be calculated for each time frame after the surgery. ACUR is equal to average health-related costs generated over a time frame divided by average Quality-Adjusted Life years (QALYs) gained over the same time frame. Health-related costs will include all direct and indirect costs before and after surgery (from questionnaires administered to patients and financial data taken from the cost accounting system of the facility). Data on health-related quality of life collected using the EuroQol-5 Dimension questionnaire (EQ-5D-5L) will inform the QALYs calculation.

  Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery

• Change in functional outcomes measured by total scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire

  The WOMAC questionnaire consists of 24 questions. The overall WOMAC score (index) is determined by summing the scores across the three dimensions of pain (score ranges from 0 to 20), stiffness (score ranges from 0 to 8), and physical function (score ranges from 0 to 68).

  Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery

• Change in quality of life indicators measured by the 5-level version of the EuroQol-5 Dimension questionnaire (EQ-5D-5L) health profile (state), index and the visual analogue scale score (EQ VAS)

  The EQ-5D-5L questionnaire consists of 5 questions in 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. In the 5-level version of the questionnaire, each domain has 5 levels. The 5 answers to the 5 questions are combined into a 5-digit number that describes the patients' health profile (state). The 5-digit number can be converted into a single summary index value, which reflects how good or bad a person's health is relative to the general population of a country or region. Another part of the questionnaire is the EQ-VAS which records the patients' self rated-health on a scale from 0 to 100, where 0 = the worst imaginable health and 100 = the best imaginable health.

  Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery

Secondary Outcomes (1)

• Level of patients' satisfaction with the primary total knee arthroplasty procedure and overall treatment at the facility

  Up to 7 days after the surgery

Study Arms (1)

Knee arthroplasty

All adult patients undergoing primary total knee replacement surgery at the Traumatology, Orthopedics and Joint Pathology Clinic of the I.M. Sechenov First Moscow State Medical University (Sechenov University) who meet the inclusion criteria (described below) will be included.

Other: Questionnaire administration

Interventions

Questionnaire administration OTHER

All study participants will be surveyed with the EQ-5D-5L questionnaire to measure their quality of life indicators before the primary total knee arthroplasty and after the surgery (on 4 dates over a 1-year period); the WOMAC questionnaire to measure their functional outcomes before the primary total knee arthroplasty and after the surgery (on 4 dates over a 1-year period); the costs questionnaire to measure direct and indirect costs borne by patients because of their condition before the primary total knee arthroplasty and after the surgery (on 4 dates over a 1-year period).

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

Patients with degenerative joint disease who are undergoing primary total knee arthroplasty at the Traumatology, Orthopedics and Joint Pathology Clinic of the I.M. Sechenov First Moscow State Medical University (Sechenov University)

You may qualify if:

• Patient is aged 18 years and over
• Patient is willing and able to provide written informed consent to participate in the study including the pre-surgery questionnaire and all post-surgical follow-up questionnaires
• Patients is diagnosed with degenerative joint disease and are admitted to the Traumatology, Orthopedics and Joint Pathology Clinic of the I.M. Sechenov First Moscow State Medical University (Sechenov University) to undergo primary total knee arthroplasty

You may not qualify if:

• Patient is unable to provide written consent due to illness or personal circumstances
• Patient is cognitively unable to complete study questionnaires
• Patient refuses to participate in any of the pre-surgery and post-surgical outcome measures (e.g., refuses to provide their contact information for follow-up surveys)
• Patient has an existing condition that would compromise their participation and follow-up in the study (e.g., neuromuscular and psychiatric disorders, musculoskeletal cancer)
• Patient is a pregnant woman
