The ASES evaluation generally has a patient self-evaluation section and a physician assessment section. The patient self-evaluation section of the form contains visual analog scales for pain, instability, an activities of daily living (ADL) questionnaire. The physician assessment section includes an area to collect demographic information and assesses range of motion, specific physical signs, strength, and stability. A shoulder score can be derived from the visual analogue scale score for pain (50%) and the cumulative activities of daily living score (50%) (Richards, Bigliani, Gartsman, Iannotti, & Zuckerman, 1994). The ASES evaluation has a total of 100 points possible; with 100 being the best possible outcome, and 0 being the worst.

The Constant-Murley Shoulder Score is a 100-point functional shoulder assessment tool in which higher scores reflect increased function. The subjective variables are pain (15 points) and function (Activities of Daily Living - sleep, work, recreation/sport) (20 points), for a total of 35 points. The objective variables are active range of motion (clinician assessment) (40 points) and strength (25 points), for a total of 65 points (Stiller & Uhl, 2005).

The Simple Shoulder Test (SST): a series of 12 "yes" or "no" questions the patient answers about the function of the involved shoulder; 2 questions relate to pain, 7 questions relate to function and 3 questions relate to range of motion. The answers to these questions (yes = 1, no = 0) provides a standardized way of recording the function of a shoulder before and after treatment (McClure & Michener, 2003). A score of 12 on the Simple Shoulder test represents the best possible outcome, while a score of 0 represents the worst possible outcome.

Subjects will have MRI to assess healing of the repaired tendon at 6 and 12 months post-op. The rate of re-tear will be reported.

Two different definitions of a re-tear were used for the analysis.

1. Primary definition (used for analysis of the secondary objective): Full thickness tear that is 80% or greater in length of the original tear size.
2. Sub-analysis: Full thickness tear one centimeter or greater in length.

Complications were summarized by reporting adverse events of special interest. AEs of special interest were defined as any reported infection (incision, wound, surgical site), seroma, hematoma, inflammation (surgical site, wound), and re-tear. The re-tear rate reported in this section is the number reported via AE or surgical intervention (not the MRI results). The AEs of special interest were chosen because they are in alignment with the potential complications listed on the product insert.

Subject underwent irrigation and debridement of the shoulder, was given antibiotics, and the SAE was resolved without sequelae.
