Study summary

The purpose of the research study is to determine the efficacy and efficiency of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care, L-O (Lew-Omar), suture repair technique. The investigators will also determine if there are similar or different rates of complications and failures via both objective and subjective measures.

Read the detailed description

To determine the tendon failure/rupture rate of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care suture repair technique. The investigators will determine if there are similar or different rates of complications and failures (both intraoperatively and at 2-week, 6-week, 3-month, and 6-month post-operative intervals).

What researchers measure

Primary outcomes

  1. To determine the tendon failure/rupture rate of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care suture repair technique. Also to determine if there are similar or different rates of complications and failures

    Time frame: From enrollment to end of postoperative follow up at 6-months.

Secondary outcomes

  1. Time to Repair

    The units measured will be minutes/seconds for repair

    Time frame: From enrollment to end of postoperative follow up at 6-months

  2. Visual Analog Pain Scale

    Visual number scale to rate pain

    Time frame: From enrollment to end of postoperative follow up at 6-months

  3. Quick DASH Form

    Assessment of symptoms and ability to perform certain activities.

    Time frame: From enrollment to end of postoperative follow up at 6-months

  4. Patient Satisfaction Questionnaire

    Assessment of perceptions of technical quality, interpersonal manner, communication, financial aspects, time spent with the doctor, accessibility, and convenience, as well as overall general satisfaction.

    Time frame: From enrollment to end of postoperative follow up at 6-months

  5. Grip/Strength Assessment

    Measured using a hand-held dynamometer in units of pounds/kilograms

    Time frame: From enrollment to end of postoperative follow up at 6-months

  6. Range of Motion Assessment

    Measured using a goniometer and recorded in degrees.

    Time frame: From enrollment to end of postoperative follow up at 6-months

  7. Surgical Time

    Total surgical time recorded in minutes.

    Time frame: From enrollment to end of postoperative follow up at 6-months
