Radiological Evaluation of 3D Printed Porous Collars in Hip and Knee Resection Prostheses: Pilot Study.
An observational study of Bone Tumor, run by Regina Elena Cancer Institute at 1 site in Italy.
Trial summary
This study aims to evaluate the osseointegration of 3D printed porous collars in hip and knee resection prostheses, in order to eliminate one of the causes of diaphyseal osteolysis, which often lead to loosening of the implants, and therefore to guarantee a further improvement in fixation of the implants in terms of… Read more about this study

About this study
Official title: Radiological Evaluation of 3D Printed Porous Collars in Resection Prostheses Hip and Knee: Pilot Study.
This study aims to evaluate the osseointegration of 3D printed porous collars in hip and knee resection prostheses, in order to eliminate one of the causes of diaphyseal osteolysis, which often lead to loosening of the implants, and therefore to guarantee a further improvement in fixation of the implants in terms of both primary and secondary stability.
Read the detailed description
Non-interventional, retro-prospective, non-pharmacological multicenter pilot study.
The objective of the study is the radiological and clinical evaluation of collar osteointegration porous 3D printed in hip and knee resection prostheses.
Aims to enroll patients undergoing resection prosthesis surgery hip and knee with the use of 3D printed porous collars, performed according to normal practice clinic at the institutions participating in the study.
It is structured in a retrospective part which will evaluate the patients for whom follow-up data is available at the time of the start of the study up to at least 1 year after the operation. And a prospective part (both with regard to patients not yet subjected to intervention, at the start of the study, according to the inclusion criteria, both regarding those in follow-up for whom data are not available according to the time of observation required (1 year)) which will begin once all the necessary authorizations have been obtained administrative requests.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Retrospective part | Patients for whom follow-up data up to at least 1 year after surgery is available at the start of the study. | |
| Prospective part | Both for patients not yet undergoing treatment intervention, at the start of the study, according to the inclusion criteria, both regarding those in follow-up for whom data are not available according to the time of observation required (1 year), will begin once all necessary authorizations have been obtained administrative requests |
What is being measured
The primary outcome is the main question the study is designed to answer.
Radiological evaluation
Osseointegration will be assessed by x-ray analysis 6 months and 1 year after surgery
Measured: 6 months and 1 year
Secondary outcomes (1)
QoL evaluation
Patient satisfaction/quality of life will be assessed 6 months and 1 year after surgery validated clinical questionnaire (Oxford score).
Bone remodeling will be evaluated by x-ray analysis 6 months and 1 year after surgery. Number of adverse events of any nature during follow-up. Highlight any inter-observer variability in the detection of radiological measurements.
Measured: 6 months and 1 year

Questions about this trial
What is this clinical trial studying?
An observational study of Bone Tumor, run by Regina Elena Cancer Institute at 1 site in Italy.
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 7 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 22 Mar 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 Italy. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Nicola Salducca (06-5266.6894, nicola.salducca@ifo.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiological evaluation (time frame: 6 months and 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 22 Mar 2024; AzTrials last refreshed its copy on 7 Nov 2026.
