Study Details

Study Description

Brief Summary

This study will evaluate the subscapularis repair versus non-repair during a reverse shoulder arthroplasty (RSA).

Condition or Disease Intervention/Treatment Phase
  • Device: Repair of the subscapularis
N/A

Detailed Description

The primary objective of this study is to evaluate pain and function in patients undergoing RSA with or without subscapularis repair. This primary outcome will be measured by analysis of Constant scores at two years post-operative.

Secondary objectives are to evaluate pain, function and imaging, between the two groups at each applicable time point.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Reverse Shoulder Arthroplasty with subscapularis repair

The subscapularis will be repaired using the "suture through bone and prosthesis holes" surgical technique.

Device: Repair of the subscapularis
The subscapularis will be repaired using the "suture through bone and prosthesis holes" surgical technique.

No Intervention: Reverse Shoulder Arthroplasty without subscapularis repair

The subscapularis will not be repaired.

Outcome Measures

Primary Outcome Measures

  1. Constant-Murley Shoulder Outcome Score [Collected at at pre-op, but the primary outcome is the score at 2 years post-procedure.]

    A combination of objective measures and patient-reported outcomes. It defines the level of pain and the ability to carry out the normal daily activities of the patient. It is a 0-100 point scale, the higher the score, the higher the quality of the function.

  2. Constant-Murley Shoulder Outcome Score [Collected at at 9 week post-op timepoint, but the primary outcome is the score at 2 years post-procedure.]

    A combination of objective measures and patient-reported outcomes. It defines the level of pain and the ability to carry out the normal daily activities of the patient. It is a 0-100 point scale, the higher the score, the higher the quality of the function.

  3. Constant-Murley Shoulder Outcome Score [Collected at at the 26 week post-op timepoint, but the primary outcome is the score at 2 years post-procedure.]

    A combination of objective measures and patient-reported outcomes. It defines the level of pain and the ability to carry out the normal daily activities of the patient. It is a 0-100 point scale, the higher the score, the higher the quality of the function.

  4. Constant-Murley Shoulder Outcome Score [Collected at at 1 year post-op timepoint, but the primary outcome is the score at 2 years post-procedure.]

    A combination of objective measures and patient-reported outcomes. It defines the level of pain and the ability to carry out the normal daily activities of the patient. It is a 0-100 point scale, the higher the score, the higher the quality of the function.

  5. Constant-Murley Shoulder Outcome Score [Collected at the 2 year post-op timepoint, and is the primary outcome measure]

    A combination of objective measures and patient-reported outcomes. It defines the level of pain and the ability to carry out the normal daily activities of the patient. It is a 0-100 point scale, the higher the score, the higher the quality of the function.

Secondary Outcome Measures

  1. Ultrasound [Collected once at either the 6 month, 1 year or 2 year timepoint.]

    Evaluation of the subscapularis complex in patients that have been randomized to "repair of the subscapularis" to examine the subscapularis complex. Ultrasound scans will be read and the integrity of the subscapularis complex will be determined by the clinician to be "intact", "attenuated", "partial tear" or "complete tear".

  2. American Shoulder and Elbow Surgeons (ASES) subjective survey [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    A combination of objective measures and patient-reported outcomes, it measures pain and functional limitations in the shoulder. The objective questionnaire allows documentation of range of motion in the patient.

  3. Simple Shoulder Test (SST) questionnaire [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    Provides a standardized way of recording the function of a shoulder before and after treatment.

  4. Visual Analog Scale (VAS) [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    The standard measure for pain on a 0-10 scale, 10 being the worst.

  5. Western Ontario Osteoarthritis of the Shoulder Index (WOOS) [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    A patient administrated questionnaire for measurement of the quality of life. It provides scores on four domains: 1.) physical symptoms, 2.) sport, recreation, and work, 3.) lifestyle and 4.) emotions.

  6. Veterans Rand 12 Item Health Survey (VR-12) [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    A self-administered health measure. Answers are summarized into two scores, a Physical Component Score and a Mental Component Score, which provides an important contrast between the respondents' physical and psychological health status.

  7. Single Assessment Numeric Evaluation score (SANE) [Collected at pre-op, 9 weeks, 26 weeks, 1 year and 2 year post-op timepoints.]

    Asks patients to rate shoulder pain as a percentage of normal.

  8. Standard Pre-Operative Form [Collected at the pre-op visit.]

    A patient administered form that asks patients to evaluate their expectations of their scheduled Arthroplasty procedure.

  9. Return to Work Form [Collected at pre-op, 26 weeks and 1 year.]

    A patient administered form that asks patients to determine the effect that their shoulder has had on their employment.

  10. Standard Late Postoperative Form [Collected at the 1 year and 2 year timepoints.]

    A patient administered form that asks patient to evaluate if their expectations were met regarding their Arthroplasty procedure.
