Trial Outcomes & Findings for Comparison of BioCartilage Versus Marrow Stimulating Procedure for Cartilage Defects of the Knee (NCT NCT02203071)

NCT ID: NCT02203071

Last Updated: 2020-03-16

Results Overview

The primary endpoint is to determine whether subjects receiving a marrow stimulating procedure (MSP) augmented with BioCartilage have improved outcomes (MRI) compared to subjects who receive MSP without the use of BioCartilage. Quantitative (%fill) and qualitative (tissue quality) MRI assessments of repair tissue will be performed by a musculoskeletal (MSK) radiologist who is blinded to treatment group, and compared for differences between treatment groups.

PRIMARY outcome

Timeframe: 1 year post-operatively

Population: There were 6 screen fails and 10 enrolled subjects who did not complete the study. Fifteen patients who were screened, consented, and enrolled, completed the 2-year study. Five patients who completed the study were assigned to the MSP treatment group and ten were assigned to the BioCartilage treatment group.

SECONDARY outcome

Timeframe: Approximately 2 years

Population: There were 6 screen fails and 10 enrolled subjects who did not complete the study. Fifteen patients who were screened, consented, and enrolled, completed the 2-year study. Five patients who completed the study were assigned to the MSP treatment group and ten were assigned to the BioCartilage treatment group.

The 12-item Short Form Survey (SF-12) is a general health questionnaire. The SF-12 was constructed using questions drawn from each of the 8 dimensions of the MOS 36 item Short Form Survey (SF-36). It is designed to have similar performance to the SF-36, while taking less time to complete. Two summary scores are reported from the SF-12 - a mental component score (MCS-12) and a physical component score (PCS-12). Physical and Mental Health Composite Scores (PCS \& MCS) are computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.

The Marx Scale consists of four questions concerning four activities or actions: running, cutting, deceleration, and pivoting. The patient or survey respondent is asked to report on the frequency with which they performed the activity in their healthiest state within the past year. The four knee functions are rated on a 5-point scale of frequency and scores are added up to a minimum score of 0 and a maximum of 16 points, with a higher score indicating more frequent participation.

The Knee injury and Osteoarthritis Outcome Score (KOOS) assesses patient pain (9 items), other symptoms (7 items), function in daily living (17 items), function in sport and recreation (5 items), and knee related quality of life (4 items). Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms. The KOOS is a patient reported joint-specific score, which may be useful for assessing changes in knee pathology over time, with or without treatment.

The IKDC Questionnaire is a subjective scale that provides patients with an overall function score. The questionnaire looks at 3 categories: symptoms, sports activity, and knee function. The symptoms subscale helps to evaluate things such as pain, stiffness, swelling and giving-way of the knee. Meanwhile, the sports activity subscale focuses on functions like going up and down the stairs, rising from a chair, squatting and jumping. The knee function subscale asks patients one simple question: how is their knee at present versus how was their knee prior to injury? Scores are obtained by summing the individual items, then transforming the crude total to a scaled number that ranges from 0 to 100. This final number is interpreted as a measure of function with higher scores representing higher levels of function.

This is a two question survey administered to subjects that obtains subjective data "Yes / No" regarding whether the subject has been able to return to work or sports activity since surgery.
