Patients undergoing total knee arthroplasty who received interspace between the popliteal artery and capsule of the posterior knee block and adductor canal block had significantly better pain control, significantly less opioid , according to results presented at the World Congress on Regional Anesthesia & Pain Medicine.

Kim, MD, anesthesiologist at Hospital for Special Surgery and co-author of the study, told Healio.com/Orthopedics.
