MDR - PMCF Study for Taperloc Complete Stems

This study is a long-term follow-up registry for patients who have received the Taperloc Complete hip stem implant during hip replacement surgery. The goal is to collect real-world data on how well this implant performs over time — including how often complications arise and how patients' quality of life and function improve after surgery. This type of study, called a Post-Market Clinical Follow-up (PMCF), is required to ensure medical devices continue to meet safety and performance standards after they are approved. Participants will be followed over several years with periodic check-ins. You may be eligible if: - You are 18 years of age or older and skeletally mature - You have undergone primary or revision hip replacement surgery using the Taperloc Complete stem - Your surgery was for osteoarthritis, avascular necrosis, rheumatoid arthritis, functional deformity, or certain hip fractures - You are willing to sign informed consent You may NOT be eligible if: - You have an active infection, sepsis, or osteomyelitis - You have significant osteoporosis, bone loss, or metabolic bone disease - You have a neurological or psychiatric condition that prevents following study directions - You are pregnant, a prisoner, or a known substance abuser Talk to your doctor to see if this trial is right for you.
