简要总结
Arthroscopic meniscal procedures are the most commonly performed orthopaedic procedure in the U.S. affecting 15% of Americans ages 10-65 years. Meniscus injury is also known to increase the risk of posttraumatic osteoarthritis (PTOA). The current randomized clinical trial will test a novel intervention after meniscal repair that combines an oral senolytic fisetin and real-time biofeedback program to restore joint loading and subsequent return to activity.

Arthroscopic meniscal procedures are the most commonly performed orthopaedic procedure in the U.S. affecting 15% of Americans ages 10-65 years. Meniscus injury is also known to increase the risk of posttraumatic osteoarthritis (PTOA). The current randomized clinical trial will test a novel mechanobiologic intervention after meniscal repair that combines an oral senolytic fisetin and real-time biofeedback program to restore joint loading and subsequent return to activity. The premise for this program is derived from growing evidence that under-loading early after an orthopedic surgery is a major contributing factor to future PTOA development. Despite the need to assess how much force the patient can produce in various exercises to better inform progression and progress, clinicians still have few tools. By providing the realtime feedback during all exercises, the program will promote the recovery of muscle function as well which is critical for normal joint loading.
The study will 1) evaluate the feasibility and acceptability of the mechanobiologic intervention following arthroscopic repair of meniscus tears, 2) determine if the mechanobiologic intervention improves physical function, patient reported outcomes, loading and muscle strength, and biomechanical symmetry in comparison to standard of care physical therapy and oral placebo, and 3) compare cartilage composition at 1 year after meniscus surgery between the mechnobiologic intervention and a control group treated standard of care physical therapy and oral placebo.

盲法说明
The study pharmacist that prepared the randomization schedule will meet with the pre-specified unblinded study personnel prior to the site initiation visit. The unblinded personnel will then prepare sealed envelopes that contain each subject's group assignment.
The investigators will designate, a priori, study personnel that will be unblinded. These unblinded personnel will be directly involved with maintaining the drug log and communicating with participants to schedule physical therapy sessions. The unblinded pharmacist/coordinator will access the actual treatment assignment but both blinded study personnel and the patient will not know the patient's treatment assignment. The Investigator, participant, patient assessors, laboratory personnel, and statistician will remain blinded throughout the study.

- •Patients who have undergone arthroscopic surgery (including microfracture and meniscectomy) on the Study Knee in the last 2 years prior to the Screening visit.
- •Patients will be excluded from the study if an Outerbridge grade III or IV chondral lesion is identified during arthroscopy.
- •Radiographic osteoarthritis (Kellgren-Lawrence Grade 2-4), full thickness chondral defect on MRI, BMI > 35 kg/m2, concomitant ligament injury, or prior ipsilateral knee ligament or meniscus surgery within prior 12 months of enrollment.
- •The following intraarticular injections:
- •Glucocorticoid within the last 2 months,
- •Extended-release corticosteroid, hyaluronic acid, or other biologic injection (platelet-rich plasma, bone marrow, adipose tissue/cells) into the Study Knee in the past 6 months within the past 6 months
- •Subjects with any of the following drug/medication statuses:
- •Currently taking Losartan;
- •Currently taking Warfarin or related anticoagulants;
- •Opioid analgesics taken in the past 8 weeks;
- •Senolytic agents taken within the past 6 months and are not willing to discontinue these medications through the duration of the study, including: Fisetin, Quercetin, Luteolin, Dasatinib, Piperlongumine, or Navitoclax;
- •Drugs that induce significant cellular stress and are not willing to discontinue these medications through the duration of the study, including alkylating agents, anthracyclines, platins, other chemotherapy drugs;
- •Medications that are sensitive substrates or substrates with a narrow therapeutic range for CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4, OATP1B1 or strong inhibitors or inducers of CYP3A4 (e.g. cyclosporine, tacrolimus or sirolimus);
- •Subjects taking the following other drugs if they cannot be held (per the Principal Investigator) for at least 2 days before and during administration of Fisetin: cyclosporine, tacrolimus, repaglinide, and bosentan.
- •Subjects with any of the following disease statuses:
- •Significant liver disease (i.e. greater than or equal to 2x the upper limit of normal bilirubin levels) or as in the opinion of the Principal Investigator;

Fisetin
Subjects assigned to the experimental group will take approximately 20 mg/kg/day of fisetin for 2 consecutive days, followed by a 28-day senescence washout period, and then another 2-day administration. Fisetin treatment begins at 8 weeks after surgery.
干预措施: Fisetin (Drug)
Placebo
Subjects assigned to the experimental group will take approximately 20 mg/kg/day of placebo (corn starch) for 2 consecutive days, followed by a 28-day washout period, and then another 2-day administration. Placebo treatment begins at 8 weeks after surgery.
干预措施: Placebo oral capsule (Drug)
