A study testing No Xray and Xray in people with Prosthetic Knee Surgery, run by Corporacion Parc Tauli at 1 site in Spain.
Trial summary

About this study
Official title: Prospective Randomized Study of the Clinical Utility to Follow-up Radiographs During the First Year of Knee Replacement Surgery
Primary prosthetic surgery for the treatment of gonarthrosis is currently one of the most prevalent surgical treatments in Traumatology. The Arthroplasty Register in Catalonia, which started in 2005, counted more than 60.000 knee prothesis until 2015. Regarding the peridiocity for taking control radiographs in patients undergoing knee replacement surgery, there is no consensus. This means, that in similar studies that evaluate the results of prosthetic surgery, there is a great variability in radiological follow-up protocols, especifically during the firts post-operative years. Given the high prevalence and the long survival period demonstrated by these implants, it seems reasonable to be able to establish the real value of the radiographs performed during the first year of follow-up after surgery. From this perspective, the aim of our study is to evaluate if conducting just two radiographs instead of five during the first postoperative year after the surgery, has any influence on the clinical and functional results of our patients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Primary prosthetic surgery for the treatment of gonarthrosis is currently one of the most prevalent surgical treatments in Traumatology. The Arthroplasty Register in Catalonia, which started in 2005, counted more than 60.000 knee prothesis until 2015. Regarding the peridiocity for taking control radiographs in patients undergoing knee replacement surgery, there is no consensus. This means, that in similar studies that evaluate the results of prosthetic surgery, there is a great variability in radiological follow-up protocols, especifically during the firts post-operative years. Given the high prevalence and the long survival period demonstrated by these implants, it seems reasonable to be able to establish the real value of the radiographs performed during the first year of follow-up after surgery. From this perspective, the aim of our study is to evaluate if conducting just two radiographs instead of five during the first postoperative year after the surgery, has any influence on the clinical and functional results of our patients.

Questions about this trial
What is this clinical trial studying?
A study testing No Xray and Xray in people with Prosthetic Knee Surgery, run by Corporacion Parc Tauli at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
KSS Test change (time frame: Preoperative, 6 and 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05944679, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2024.
