Trial Outcomes & Findings for Exceed ABT Acetabular Cup Cementless System (NCT NCT04255394)

NCT ID: NCT04255394

Last Updated: 2024-07-26

Results Overview

Clinical performance - as measured by clinical score data (HHS). The HHS was developed for the assessment of the results of hip surgery, and is intended to evaluate various hip disabilities and methods of treatment in an adult population. The domains covered are pain, function, absence of deformity, and range of motion. The score has a minimum of 0 and a maximum of 100 points. The scale: Excellent:90 - 100, Good: 80 - 89, Fair: 70 - 79, Poor: \< 70.

PRIMARY outcome

Timeframe: 10 years

Clinical performance - as measured by clinical score data - womac pain The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic duties The scores for each subscale are summed up, with a possible score range of 0-20 for pain, 0-8 for stiffness, and 0-68 for physical function. A higher score indicates a worse clinical outcome. Womac pain score is reported here.

SECONDARY outcome

Timeframe: 10 years

The Oxford hip score (OHS) is self-completion patient-centered outcome measure tool designed to assess disability in patients undergoing total hip replacement. The OHS consists of 12 questions about pain and disability experienced over the past four weeks. Each item has five response categories, given a score of between 1-5 (low disability to high disability). Scoring involves summating the total for each item to produce a final score between 12-60, with a higher score indicating greater disability (old Oxford score).
