Runge C, et al. - Researchers assessed the analgesic impact of adding a popliteal plexus block (PPB) to an femoral triangle block (FTB) in subjects with significant pain after total knee arthroplasty (TKA), presuming that a popliteal plexus block (PPB) as a supplement to an FTB would reduce pain after TKA without anaesthetising motor branches from the sciatic nerve in the popliteal fossa. They focused on the proportion of subjects with pain above numeric rating scale (NRS) 3 followed by a reduction to NRS 3 or below following a PPB. They found that addition of a PPB to an FTB brought about effective pain relief without influencing the ankle muscle strength in all subjects with significant pain after TKA.
