Correction of Functional Deformity
Osteoarthritis

Registration Number: NCT04255394

Lead Sponsor: Zimmer Biomet

Brief Summary: A Post-market Clinical Follow-up Study to provide safety, performance and clinical benefits data on the Exceed ABT acetabular cup (implants and instruments) when used in combination with ceramic liners or polyethylene articulating liners bearing Options.

A single-center, cohort observational clinical outcomes study

Detailed Description: Study Aim: To collect survivorship and clinical outcomes long-term data confirm-ing safety, performance and clinical benefits of the Exceed ABT ce-mentless cup when used in combination with ceramic and polyeth-ylene articulating liners

Objectives: Primary Objectives:

Clinical performance - as measured by clinical score data (HHS, WOMAC and Oxford Hip Score), radiographic as-sessments and survivorship which will be based on removal of the device.

Secondary Objectives:

Safety will be evaluated by monitoring incidence of adverse events. Length of study: 13 years (3 years enrollment plus 10 years follow-up): Post-operative follow-up visits at: 1, 3, 5, 7 and 10 years

Primary Outcome Measures

Name	Time	Method
Harris Hip Score	10 years	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.
10 Year Survivorship	10 years post-operative	Calculated Kaplan-Meier Survivorship based on revision of any component for any reason. Presented as the % of participants with the implant still in place 10 years post-operative.
Western Ontario and McMasters Universities Osteoarthritis Index-WOMAC Pain Score	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 Measures

Name	Time	Method
Oxford Hip Score	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).
