An interventional study of THA in Osteoarthritis and Degenerative Arthritis, sponsored by DePuy Orthopaedics. Terminated at 3 sites in Canada. Open to participants aged 21 Years and older. Per ClinicalTrials.gov, last updated 2025-12-19.

The primary objective is to establish the mean superior cup migration of the Pinnacle Acetabular Shell using model-based RSA over the first two years post-implantation. The primary endpoint is the mean vertical subsidence (Y translation, also known as superior cup migration) at 2 years as measured with RSA. This will be summarized for each surgical approach separately, as well as combined.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Mean Superior Cup Migration (Subsidence) at 6 Week and 2 Years

Time frame: At 6 week and 2 years
Patient Reported Outcome Measures (PROMs)- HOOS Jr.
Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) is a patient reported joint-specific score designed to evaluate outcomes after total hip arthroplasty. It assesses patient pain (2 items), and functions of daily living (4 items). Response to each item is scored from 0 (none) to 4 (extreme). Raw scores are added up and then converted to an interval score (0-100) using an interval table. The final interval score represents a patients total joint disability where 0 corresponds to total joint disability (worse outcome) and 100 is perfect joint health (best outcome).
Time frame: Pre Operation (-Day90 to Day 0), At 6 weeks, 3 months, 6 months, 1 year and 2 years
Patient Reported Outcome Measures (PROMs)- FJS-12
The Forgotten Joint Score (FJS-12) is a patient-reported outcome measure intended to determine a patient's ability to "forget" about their affected joint after surgery or treatment. The Forgotten Joint Score consists of 12 questions with response ranging from 0 (never) to 4 (mostly). All responses are summed and then divided by the number of completed items. This mean value is subsequently multiplied by 25 to obtain a total score range of 0 to 100. Finally, the score is subtracted from 100, to change the direction of the final score in a way that high scores indicate a high degree of "forgetting" the artificial joint, that is, a low degree of awareness.
Time frame: At 6 weeks, 3 months, 6 months, 1 year and 2 years

Patient Reported Outcome Measures (PROMs)- Harris Hip Score
The Harris Hip Score (HHS) has 10 items with four subscales comprising a minimum of 0 points and a maximum of 100 points with higher scores representing better function and outcomes. The four subscales include: pain severity, activities of daily living, absence of deformity and range of motion. Scoring is done according to the following: 90-100 = excellent, 80-89 = good, 70-79 = fair, 60-69 = poor, and below 60 is a failed result.
