This week we welcome Dr. Jamie Collins, lead author of “Five-Year Structural Changes in the Knee Among Patients With Meniscal Tear and Osteoarthritis: Data From a Randomized Controlled Trial of Arthroscopic Partial Meniscectomy Versus Physical Therapy“. We discuss this study’s methods, statistical results and what all that data indicates about the role of exercise and surgery. Later, Dr. Collins offers advice for non-clinicians working with clinicians and explains what it's like being a mathematician analyzing data in the field of rheumatology and how she came to pursue her own research and write her own grants within the field.
