Brief summary

The purpose of the study is the evaluation of the clinical and radiological short- to long-term safety and performance of the RM Pressfit vitamys cup. The data will be used for an ongoing evaluation of the product safety and performance.

Detailed description

Prospective multicenter follow-up study which examines the short- to long-term post-market clinical data on the safety and performance of the RM Pressfit vitamys cup. In total 675 participants in 9 clinics are included in this international multicenter study. The primary endpoint of the study is the Harris Hip Score (HHS) 2 years after surgery. The following parameters will be collected during the regular clinical and radiological follow-up: Harris Hip Score, radiographic evaluation and detection of adverse events.

Design outcomes

Primary

MeasureTime frameDescription
Harris Hip Score (modified after Haddad et al, 1990)2 yearsThe primary endpoint of the study is the Harris Hip Score (HHS) 2 years after surgery. The HHS is a measure of dysfunction so the higher the score, the better the outcome for the individual. The maximum score possible is 100. Results can be interpreted with the following: \<70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent.

Secondary

MeasureTime frameDescription
Radiographic evaluation6-12 weeks - 10 yearsThe second endpoint of interest is the occurence of osteolysis around the cup
Adverse Events6-12 weeks - 10 yearsReporting of Adverse Events
