The objective of this retrospective consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the JuggerKnot Mini Soft Anchor (implant and instrumentation) when used for soft tissue to bone fixation in the treatment of temporomandibular joint (TMJ) surgery. Safety, performance, and clinical benefits will be evaluated at the following time points: pre op, 6 weeks, 3 months and 1-year follow-up. JuggerKnot Mini has been on the market since November of 2011.
The primary objective is to confirm safety of the study products. This will be assessed by recording the incidence and frequency of revisions, complications, and adverse events. Relationship of the events to either implant or instrumentation should be specified. The secondary objective is the assessment of performance and clinical benefits by analyzing recorded patient-reported clinical outcomes measures (PROMs).
Study Type
OBSERVATIONAL
Patient who have been implanted with one or more JuggerKnot Mini Soft Anchor(s) who have undergone repair, repositioning or reattachment of soft tissues, ligament and tendons to the mandible is require for surgical stabilization of the TMJ articular disc.
Device Safety Assessed Through the Incidence and Frequency of Revisions, Complications, and Adverse Events
Assessment of safety by recording and analyzing the incidence and frequency of revisions, complications, and adverse events.
Time frame: Out to a minimum of 1 year
Device performance and Clinical Benefits Assessed by a Pain Assessment. and Temporomandibular Joint Function of the Pain Assessment Survey Case Report Form.
Pain Assessment is used to evaluate a patients pain from 0 to 10, 0 representing no pain at all and 10 representing the worse pain imaginable.
Time frame: Out to a minimum of 1 year
Device performance and Clinical Benefits Assessed by a TMJ Function Pain Assessment Survey Case Report Form

The Joint Clicking or Popping noise is evaluated as a Yes the joint click when opening and closing the mouth, or No the joint does not click when opening and closing the mouth on either the left or right side.
Time frame: Out to a minimum of 1 year
Device performance and Clinical Benefits Assessed by a Headache Pain Assessment Survey Case Report Form
