This is a multi-center first-in-human prospective clinical investigation to evaluate the safety and performance of the FibroFix™ Cartilage P Implant and Drill Set. The Implant is a medical device designed by Orthox Ltd. to repair a damaged area of cartilage within the knee joint.
The aim is to 75 participants over two Stages:
In STAGE I, up to a total of 6 subjects will be recruited and safety assessed after 6 months of follow-up.
In Stage II an additional 69 subjects. The subjects will be followed up for 2 years with MRI imaging, then a further 8 years with patient outcome questionnaires.
This is a multi-center, prospective, non-randomized, open-label clinical investigation. Safety oversight throughout will be provided by an independent data monitoring committee (DMC). The clinical investigation will be split into two stages.
Stage I of the clinical investigation will enroll a small cohort of subjects, up to a total of 6 (accounting for a 17% dropout rate) having been implanted with the FibroFix Cartilage P, to provide a minimum of 5 evaluable subjects. The initial safety of the FibroFix Cartilage P implant and the FibroFix Cartilage P Drill Set will be evaluated in these subjects across a maximum of 2 sites. Recruitment into the clinical investigation will then be paused.
Following the implantation of FibroFix Cartilage P in the initial cohort of subjects, the DMC will monitor all emerging safety issues against the stopping rules of the clinical investigation. Any treatment-emergent Serious Adverse Events (SAE) or other safety concerns during Stage I of the clinical investigation will immediately be referred, on a case-by-case basis, to the DMC for review against the stopping rules.
A formal review of safety against the stopping rules will be undertaken by the DMC at two-time points:
Each DMC review will be triggered by the last subject within the safety cohort completing the relevant 3-month and 6- month post-surgery follow-up activities, respectively.
The re-opening of recruitment will only be triggered by authorization from the DMC to proceed.
Stage II of the clinical investigation will evaluate the performance and safety of FibroFix Cartilage P and the FibroFix Cartilage P Drill Set in a wider group of subjects, a further 69 recruited from all participating clinical centers to provide 60 evaluable out of 75 recruited subjects who have been implanted with the FibroFix Cartilage P, allowing for 20% drop out rate.
Stage I (safety cohort) subjects will be analyzed with the Stage II subjects as an overall cohort unless amendments to the treatment protocol and/or medical device are required following the evaluation of the safety cohort.
Primary outcomes will be reported in an interim report following completion of the 1-year post-surgery follow-up. All subjects will be follow-up for a total of 2 years post-surgery after which a final clinical study report will be written.
All participants in this clinical investigation will receive a single appropriately sized FibroFix Cartilage P implant, surgically implanted using the corresponding FibroFix Cartilage P Drill Set.
If it is not possible to implant FibroFix Cartilage P during surgery because the lesion is too large or, if once debrided the area is too large for study implant, the standard of care will be implemented at the discretion of the surgeon, and any adverse events related to use of the FibroFix cartilage P Drill Set will be followed.
The objective of Stage I, the initial safety cohort, will be to demonstrate the safety of FibroFix Cartilage P implant in a small number of subjects at 3- and 6-month post-surgery follow-up, and FibroFix Cartilage P Drill Set intraoperatively.
The objective of Stage II, Full cohort, will be to demonstrate the performance and safety of FibroFix Cartilage P implant at 1-year post-surgery follow-up, and FibroFix Cartilage P Drill Set intraoperatively. Performance of FibroFix Cartilage P will be determined by change in the Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain and Function (Sport/Rec) scores from baseline at 1-year post-surgery follow-up.
The null hypothesis being tested is the mean improvement in KOOS pain score at 1-year post-surgery from baseline is less than or equal to 8 points versus the alternative hypothesis that the mean improvement is greater than 8 points.
Subject participation will last 2 years and will require several visits to the doctor's office. Screening:
Subjects who are potential candidates for the clinical investigation will be identified by clinical research team members at the clinical centers involved. During the Screening phase, the following assessments will be performed:
Pre-operative Assessment:
If the subject has consented to participate and meets the inclusion criteria but none of the exclusion criteria, the following baseline assessments will be conducted. The subject's following medical history and medication history will be reviewed as part of this baseline assessment: demographics, patient history, and physical (review of systems, allergies, vital signs, physical examination, MRI assessment available to provide diagnosis, and urine pregnancy test for female subjects), concomitant medications, and MRI will be reviewed and baseline questionnaires (KOOS, Lysholm Knee Score and Tegner Activity Scale, Visual Analogue Scale (VAS) Pain, EuroQol 5-Dimension 5-Level (EQ-5D-5L), and Kellgren and Lawrence system) will be completed.
Post-operative Assessment:
For the study, subjects have to visit the hospital 6 times over 2 years (at 2w, 6w, 3m, 6m, 1y, and 2y). During all the follow-up visits, concomitant medications and safety events will be reviewed and subjects have to complete the VAS Pain, Lysholm, and Tegner activity questionnaires. In addition, during all visits except the 2w visit, subjects have to complete the KOOS questionnaire. During the 6m, 1y, and 2y visits, patients also have to complete the EQ-5D. An MRI will be conducted at 3m, 6m, 1y, and 2y.
Participants will then be followed up for a further 8 years for Device related adverse events and the same patient outcome questionnaires.

| Change in EQ-5D-5L -month 6 | Change from baseline in the EQ-5D-5L score. The EuroQol 5-Dimension 5-Level (EQ-5D-5L) score is a standardised measure of health status developed by the EuroQol Group to provide a simple, generic measure of health for clinical and economic appraisal. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. | baseline (pre-surgery) to month 6 after surgery |

| Usability Questionnaire - Surgeons and Theatre nurses | A usability questionnaire will be completed after performing the surgery to assess their opinion of using the FibroFix Cartilage P implant and Drill set by surgeons and theatre nurses. The data collected may be from open questions or using Likert scales to determine the strength of opinion. Analysis of the data collected during the formative evaluations and summative testing will be presented in the form of descriptive summaries, diagrammatic form (e.g., bar charts or histograms), and simple computation calculations such as means, standard deviations where possible, ranges of results, or percentages (e.g., percentage of people that thought…). | immediately post-surgery |
| Usability Questionnaire - Processing staff | A usability questionnaire will be completed by the processing staff after processing (cleaning and sterilizing) the Drill set (instrumentation used to prepare the implant site during surgery) to assess their opinion of the ease of cleaning and sterilizing the instruments. The data collected may be from open questions or using Likert scales to determine the strength of opinion. Analysis of the data collected during the formative evaluations and summative testing will be presented in the form of descriptive summaries, diagrammatic form (e.g., bar charts or histograms), and simple computation calculations such as means, standard deviations where possible, ranges of results, or percentages (e.g., percentage of people that thought…). | after processing of instruments |
| Usability Questionnaire - Patients | A usability questionnaire will be completed by the Patients after being given the implant card and related patient leaflet after surgery and before discharge to assess their opinion of the ease of understanding of the material given to them.
