Clinical Trial Summary

A randomised controlled study comparing two types of ultra-porous coated uncemented cups in total hip arthroplasty. Primary objective is to investigate if the clinical, radiological and patient-reported outcome of the new MobileLINK TabecuLINK cup combined with an X-LINKed insert is non-inferior to the clinical and radiological outcome of the Pinnacle Gription series 100 cup combined with the Marathon liner. Patients are evaluated up to 15 years postoperatively.


Description:

The purpose of this study is to evaluate the clinical outcome and long-term risk of development of osteolysis of a newly introduced cementless press-fit acetabular cup, consisting of a shell with a 3D surface structure and a highly cross-linked liner by precise measurement of early migration and wear. Migration describes the movement between the implant and the surrounding bone over time. Early migration of the implant, within 2 years after operation, has shown to be a strong predictor for increased risk for late failure. Thus, high precision migration studies can be used to evaluate the performance of new implants in small groups of patients with a relatively short observation time. Wear particles are one of the main causes of periprosthetic osteolysis. Although modern, more wear resistant materials, appears to have a greatly reduced risk of osteolysis, the desired complete elimination of osteolysis appears to be yet unachieved. It is most likely that the mechanism of periprosthetic osteolysis is multifactorial. In this study the investigators plan to include 70 patients that are planned for operation with an uncemented total hip arthroplasty. 35 patients will be randomized to receive the new implant and 35 patients will be included in the control group and receive a standard uncemented prosthesis. All patients will then be followed with CT scans and patient reported outcome measures 3-month, 1 year, 2 years, 5 years and 15 years after the operations. The CT scans will be used both for measurement of migration and wear and development of osteolysis around the implant.

Outcome

Type Measure Description Time frame Safety issue
Primary Early migration of the cup Migration of the cup between 3 month and 2 years after implantation of the cup measured with Computed Tomography scan based Micromotion Analysis (CTMA) in mm. 2 years after operation
Secondary Proximal wear Liner wear measured as proximal penetration of the femoral head prosthesis into the liner between 1 year and 5 years after operation in mm 5 years after operation
Secondary 3D wear Liner wear measured as 3D penetration of the femoral head prosthesis into the liner between 1 year and 5 years after operation in mm 5 years after operation
Secondary Long term migratio Migration of the cup measured in mm with CTMA 15 years after operation
Secondary Long term wear Liner wear measured in mm with CTMA 15 years after operation
Secondary Stem migration Distal and 3D migration in mm of the stem between post- operative examination and 3 month, 3 month and 2 years, 3 month and 5 years and 3 month and 15 years. 15 years
Secondary Patient reported outcome with Forgotten Joint Score Patient-reported outcome measured by Forgotten Joint Score (FSJ). The scores will be summarized and transformed to a scale ranging from 0 to 100, where a high value indicate that the patient tends to be less aware of the affected joint when performing daily activities. 15 years after operation
Secondary Patient reported outcome with Hip dysfunction and Osteoarthritis Outcome Score Patient-reported outcome measured by Hip dysfunction and Osteoarthritis Outcome Score (HOOS). Each of the 5 subscales will get a score of 0 to 100, with 0 indicating extreme symptoms and 100 indicating no symptoms. The subscales will be plotted as a HOOS profile, by connecting the mean scores for all 5 dimensions with a line. 15 years after operation
Secondary Patient reported outcome with University of California, Los Angeles Activity Score Patient-reported outcome measured by University of California, Los Angeles Activity Score (UCLA). The patients physical activity level rank from 1 (low) to 10 (high). 15 years after operation
Secondary Patient reported outcome with EuroQuol 5. Patient reported health related quality of life, measured by EuroQuol 5 dimensions (EQ-5D). For the calculation of the EQ-5D index the standard value set version 2.1 for Sweden is used. Index scores range from 0 ( 0 is the value of a health state equivalent to dead; negative values representing values as worse than dead) to 1 (the value of full health), with higher scores indicating higher health utility. 15 years after operation
Secondary Reoperations Incidence and rate of revisions, re-operations and operation-related complications 15 years after operation
Secondary Osteolysis Incidence and rate of patients showing osteolysis around the cup on CT scans and/or on x-rays 15 years after operation
Secondary Precision of migration measurements with CTMA Precision of migration measurement in mm with CTMA, by comparing double CT scans obtained on the same day at the 1 year follow-up. 1 year after operation
Secondary Precision of wear mearurements with CTMA Precision of wear measurement in mm with CTMA, by comparing double CT scans obtained on the same day at the 1 year follow-up. 1 year after operation
