Conditions

Rotator Cuff Tears

Brief summary

This is a prospective, parallel group, open-label, multi- center, randomized study to assess two accelerated rehabilitation programs for use with the InSpace device in the treatment of full thickness Massive, Irreparable Rotator Cuff Tears (MIRCTs) performed during an arthroscopic procedure.

Detailed description

Study Objectives: Primary: • To evaluate clinical outcomes of both a formalized or an at-home rehabilitation program when used in conjunction with the InSpace device as compared to the corresponding InSpace Pivotal study results. * To demonstrate consistency of each intervention group with the corresponding historical control study results. * To demonstrate that comparable clinical outcomes can be achieved for each intervention group. Secondary: • Change in clinical outcomes compared to baseline.

Design outcomes

Primary

MeasureTime frameDescription
Change in American Shoulder and Elbow (ASES) ScoreDay 0 through Month 12This is a subject self-report questionnaire and Investigator assessment questionnaire. The subject portion collects information on activities of daily living (i.e., 10 questions). The Investigator assessment portion documents ROM (forward elevation/flexion, external rotation, internal rotation, cross-body adduction), signs, strength, and instability. ASES minimal clinical important difference (MCID) and substantial clinical benefit (SCB) have been previously described for the ASES score in patients undergoing rotator cuff repair as 11.1 and 17.5, respectively. Change in American Shoulder and Elbow Surgeons (ASES) Score will be expressed as the percentages demonstrating a minimal clinical important difference (MCID; ASES ≥ 11.1) and the substantial clinical benefit (SCB; ASES ≥ 17.5) in ASES from baseline at Month 12. Minimum value: 0, Maximum value: 100 (with a higher score indicating a better outcome).

Secondary

MeasureTime frameDescription
Change in Western Ontario Rotator Cuff (WORC) ScoreDay 0 through Month 24Change in WORC Score from baseline. Minimum value: 2,100, Maximum value: 0 (with a lower score indicating a better outcome). This is a subject self-report questionnaire that is a disease-specific Quality of Life Measurement Tool specifically designed to evaluate quality of life in persons with pathology of the rotator cuff. It is comprised of 21 items in 5 domains (i.e., physical symptoms, sports and recreation, work, lifestyle, emotions).
Change in Constant Score (CS) Outcome ScoreDay 0 through Month 24Change in CS Outcome Score from baseline. Minimum value: 0, Maximum value: 100 (with a higher score indicating a better outcome). This is a self-reported questions as well as Investigator or designee performed assessment of the shoulder. The tool is divided into four subscales: pain, activities of daily living, strength and range of motion: forward elevation, external rotation, abduction and internal rotation of the shoulder.
Change in EuroQol 5-Dimensions Questionnaire (EQ-5D-5L) ScoreDay 0 through Month 24Change in EQ-5D-5L Score from baseline. Minimum value: 0, Maximum value: 100 (with a higher score indicating a better outcome). This is a subject self-report questionnaire to measure health-related quality of life (HRQOL). It consists of 5 questions capturing the subject's current health across five dimensions (i.e., mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). It also includes a numerical visual analogue scale (EQ-VAS).
Change in Visual Analog Scale (VAS) ScoreDay 0 through Month 24Change in VAS Score from baseline. This is a subject self-report questionnaire to measure pain. The patient marks on the line the point that they feel represents their perception of their current state. The amount of pain that a patient feels ranges across a continuum from none to an extreme amount of pain. (An extreme amount of pain would be considered a worse outcome)
Change in Range of Motion (ROM) ScoreDay 0 through Month 24Change in ROM Score from baseline. Minimum value: 0, Maximum value: 180 (with a higher score indicating a better outcome).
Safety AssessmentDay 0 through Month 24• Safety will be evaluated by type, frequency, severity, and relatedness of adverse events to study intervention at each follow-up visit through Month 24
Patient's satisfaction with their procedureMonth 12 and Month 24Patient Satisfaction Score at Month 12 and Month 24. This is a single-question to evaluate the patients' current state of satisfaction. Responses are binary with Yes or No answers. ('Yes' would be considered a positive outcome)
CostingDay 0 through Month 24Costs associated with all visits
Time to RecoveryDay 0 through Month 24Time to recovery by cumulative time between discharge and return to driving
Analgesia UseDay 0 through Month 24Analgesia use (drug and frequency)
Change in Single Assessment Numeric Evaluation (SANE) ScoreDay 0 through Month 24Change in SANE from baseline. Minimum value: 0%, Maximum value: 100% (with 100% being normal). This is a subject self-report questionnaire to measure function. The patient marks on the line the point that they feel represents their perception of their current state of functional improvement. Example: How would you rate your affected shoulder today as a percentage of normal (0% to 100% scale with 100% being normal)?
