Summary

Synovitis has an important role in the symptoms and progression of Osteoarthritis (OA). Inflamed synovium has been associated with both increased symptoms and increased progression in OA patients. Furthermore, synovitis observed during knee arthroscopy in our patients undergoing arthroscopic partial meniscectomy (APM) was associated with worse symptoms while adjusting for confounding factors.Therefore, a better understanding of synovitis as a predictor of outcome after APM and as a target for treatment is needed to improve outcomes in this patient population.

Triamcinolone has been shown to decrease synovitis-associated outcomes in both animal and human studies after anterior cruciate ligament (ACL) injury. In a porcine model of ACL injury, treatment with triamcinolone resulted in decreased formation of synovitis-related collagen breakdown products as well as decreased cellularity of the synovium.And in a trial of triamcinolone injected after ACL injury, similar findings of decreased C-telopeptide of type II collagen (CTX-II), associated with collagen type II breakdown, was found in knees administered triamcinolone compared to placebo controls.

Conditions

  • Osteoarthritis, Knee
  • Meniscus Tear
  • Meniscus; Degeneration
  • Synovitis

Interventions

DRUG

Zilretta Injectable Product or Placebo

The purpose of this intervention is to determine the use of extended release steroid knee injection (Zilretta) at the end of the surgery and its effects on your knee pain.In this study Zilretta will be injected intra-operatively for your arthroscopic partial meniscectomy (APM) surgery.Participants will have MRIs x-rays, and provide a sample of the synovial fluid from both knees at the beginning of surgery. This fluid is drained at the beginning of surgery and then usually discarded. Three samples each of blood and urine will be collected over the study period from each participant and sample of joint (synovial tissue) taken. Participants will be asked to answer questions about knee pain.
