“You shouldn’t be performing surgery when it’s not effective,” says Ms. Noorduyn. She notes that although one-third of their physical therapy patients elected to have surgery, she and her colleagues were unable to create a prediction model to identify these patients. Likewise, the orthopedic surgeons were unable to create a prediction model to identify which patients would be most likely to benefit from surgery.
Because guidelines state that conservative treatment should be first-line therapy, the authors suggest additional research should focus on facilitators and barriers for de-implementing arthroscopic partial meniscectomy.5
“The results are very consistent over time,” says Ms. Noorduyn. Because physical therapy is noninferior to surgery, she believes rheumatologists should recommend physical therapy and/or exercise therapy to patients with degenerative meniscal tears.
“Watchful waiting is also an option, but often patients have already done that and still have complaints,” she says. “People get a bit anxious when they have pain and wonder, ‘Should I be exercising?’” The advice from a rheumatologist to continue moving can be helpful.
Ms. Noorduyn suggests patients pursue two to three months of an incremental exercise program—with or without a physical therapist—before considering surgery. Such a program could include biking or leg raises and balancing activities working up to exercises on a balancing board. Her experience, which is consistent with the two-year data from the ESCAPE trial, is that after three months of an incremental exercise program, patient complaints decrease.
Because five years may not have been long enough to detect progression in knee OA, the team is planning a 10-year follow-up study using magnetic resonate imaging, which will address whether arthritis progresses more quickly in patients who have had their meniscal tissue removed.
“Our patients are really willing to … do the research,” Ms. Noorduyn says. “We have a follow-up rate of 78% over five years. It’s great to see.”
