Trial Outcomes & Findings for SCP Hip Outcomes Study (NCT NCT03494660)

NCT ID: NCT03494660

Last Updated: 2026-04-21

Results Overview

Change in Modified Harris Hip Score using a 0-100 overall score, from baseline at 2-years. Subscales of pain, function, and activity levels are combined to generate the overall score. Pain is scored out of 44 possible points, function is scored out of 33 possible points and subject activities are scored out of 14 possible points. The maximum score of 91 is multiplied by 1.1 to give a total score out of 100; a higher score represents better patient reported pain, function and activity levels.

Subchondroplasty Using AccuFill®
Participants underwent the subchondroplasty (SCP) procedure using AccuFill® bone substitute material. Per the Instructions for Use (IFU), the material was intended to be mixed with blood or saline; however, some participants unintentionally received off-label treatment where AccuFill® was mixed with other materials (e.g., bone marrow aspirate concentrate). All participants were analyzed together for the primary and secondary endpoints, with subgroup analyses planned for on-label and off-label treatments.

Hip function and pain were assessed using the Modified Harris Hip Score (mHHS), a validated instrument that evaluates pain, daily activities, and gait. Scores range from 0 to 100, where higher scores indicate better hip function and less pain. Change from baseline was calculated at each follow-up timepoint.

Quality of life will be assessed using the EQ-5D-5L questionnaire, which evaluates five dimensions of health: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated on five levels of severity. Responses will be converted into a single utility index score using the appropriate value set, with values typically ranging from 0 (worst health) to 1 (best health). Higher scores indicate better quality of life.

SECONDARY outcome

Timeframe: 12 Weeks

Population: The number analyzed is lower than the number enrolled because analyses included only participants with available and complete survey data for the relevant outcome measure.

The EQ-5D-5L VAS records the subject's self-rated health on a scale from 0 (worst imaginable health) to 100 (best imaginable health).

Measure
Subchondroplasty Using AccuFill®
n=66 Participants
Participants underwent the SCP procedure using AccuFill® bone substitute material. Per the IFU, the material was intended to be mixed with blood or saline; however, some participants unintentionally received off-label treatment where AccuFill® was mixed with other materials (e.g., bone marrow aspirate concentrate). All participants were analyzed together for the primary and secondary endpoints, with subgroup analyses planned for on-label and off-label treatments.
