Exceed ABT Acetabular Cup Cementless System

A Post-market Clinical Follow-up Study to Provide Safety, Performance and Clinical Benefits Data on the Exceed ABT Acetabular Cementless Cup System (Implants and Instruments)

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

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

Inclusion Criteria:

• Patients who are capable of understanding the doctor's explanations, following his instructions and are able to participate in the follow-up program

Exclusion Criteria:

• Infection, sepsis, and osteomyelitis
• Patients who are unwilling or unable to give consent, or to comply with the follow-up program
• The patient is known to be pregnant or breastfeeding
• Any vulnerable subjects (= individuals whose willingness to volunteer in a clinical investigation could be unduly influenced by the expectation, whether justified or not, of benefits associated with participation or of retaliatory response from senior members of a hierarchy in case of refusal to participate)
