Clinical Trial Summary

Horizontal meniscus tears meeting specified criteria will be repaired by any commonly used suture technique. Subjects will be followed for 2 years to evaluate the effectiveness of the repair, by assessing the re-operation rate, and by assessing improvements in knee pain and knee function.


Description:

Potential subjects will undergo Screening for eligibility based on Inclusion/Exclusion criteria. Screening will include an x-ray of the injured knee and evaluation of an MRI of the injured knee within 6 months prior to the scheduled procedure. During the procedure, the meniscal tear will be evaluated by arthroscopy to determine if the tear meets study requirements. If the meniscal tear is determined to meet inclusion/exclusion criteria, the subject will be considered enrolled. If any inclusion/exclusion criteria is not met, the subject will be considered a screen failure and will not be enrolled. For enrolled subjects, specific information regarding the repair and repair technique will be collected during the procedure, including still and video images. Subjects will be contacted 7-15 days post-procedure for safety follow-up. Subjects will return for follow-up visits at approximately post-procedure Days 90, 185, 365 and 730. Identical questionnaires will be completed at each visit to assess knee pain and knee function. Safety information will be collected at each post-procedure visit. Additionally, an in-office arthroscopy of the treated knee will be performed at participating sites at Day 185, an MRI of the treated knee will be performed at Day 365 and an X-ray of the treated knee will be performed at Day 730. The patient will exit the study at the Day 730 visit.

Outcome

Type Measure Description Time frame Safety issue
Primary Freedom From Re-operation of the Index Meniscus Repair Site (Incidence of Subjects Requiring Re-operation) Occurrence of any re-operation of study knee to treat previously repaired meniscal tear during the 2 years following the study procedure. 6 months, 1 year, and 2 years
Secondary Change in Knee Pain and Function by Completion of International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC Knee Evaluation) at 3 Months, 6 Months, 1 Year, and 2 Years Change in knee pain and function will be measured by completion of The International Knee Documentation Committee (IKDC) Subjective score. The IKDC Score was developed to detect improvement or deterioration in symptoms, function, and sports activities due to knee impairment, including patients with meniscal injuries.
There are three domains: 1) symptoms, including pain, stiffness, swelling, locking/catching, and giving way (7 items), 2) sports and daily activities (10 items), and 3) current knee function and knee function prior to knee injury (1 item, not included in the score). Responses vary for each item. The possible score ranges from 0-100, where 100 = no limitation with daily or sporting activities and the absence of symptoms.
Baseline, 3 months, 6 months, 1 year, and 2 years
Secondary Change in Knee Pain and Function by the Knee Injury and Osteoarthritis Outcome Score (KOOS): Pain Score at 3 Months, 6 Months, 1 Year, and 2 Years Change in knee pain and function will be measured by completion the Knee Injury and Osteoarthritis Outcome Score (KOOS). There are five patient-relevant subscales of the KOOS, and each are scored separately: Pain (9 items), ADL function (17 items), Sport and Recreation Function (5 items), Symptoms (7 items), and Quality of Life (4 items).
A Likert scale is used and all items have five possible answer options scored from 0 (no problems) to 4 (extreme problems). Each of the 5 scores is calculated as the sum of the items included and then each score is transformed to a 0-100 scale, with 0 representing extreme knee problems and 100 representing no knee problems as common in orthopedic assessment scales and generic measures. An aggregate score is not calculated so that each of the 5 dimensions can be assess separately.

Secondary Change in Knee Pain and Function by Lysholm Knee Questionnaire at 3 Months, 6 Months, 1 Year, and 2 Years Change in knee pain and function will be measured by completion of the Lysholm Knee Questionnaire. This tool measures the domains of symptoms and complaints and functioning of daily activities. The scale consists of 8 item and is scaled from 0 to 100, with a higher score indicating fewer symptoms and higher level of functioning. Baseline, 3 months, 6 months, 1 year, and 2 years
Secondary Change in Knee Pain and Function by Tegner Activity Scale at 3 Months, 6 Months, 1 Year, and 2 Years Change in knee pain and function will be measured by completion of the Tegner activity scale. The Tegner activity scale was designed as a score of activity level to complement other functional scores for patients with ligamentous injuries. The Tegner activity scale is a numerical scale ranging from 0 to 10. Each value indicates the ability to perform specific activities. An activity level of 10 corresponds to participation in competitive sports, including soccer, football, and rugby at the elite level; an activity level of 6 points corresponds to participation in recreational sports; and an activity level of 0 is assigned if a person is on sick leave or receiving a disability pension because of knee problems. An activity level of 5 to 10 is recorded only if the patient participates in recreational or competitive sports. Baseline, 3 months, 6 months, 1 year, and 2 years
