Up to 15% of patients report at least moderate persistent pain after TKA. Such may be associated with the presence widespread hyperalgesia and neuropathic-type pain.We asked if there was a difference among who severe or no 12 months TKA regarding (1) pressure threshold, (2) thermal (cold/heat) detection thresholds, (3) self-reported neuropathic pain.Fifty-three volunteers were recruited from reporting pain, according Knee Society Score©. Differences between moderate-to-severe no-pain groups heat cold analyzed using independent t-tests.Patients in group exhibited reduced threshold knee (p=0.025) elbow (p=0.002). This also showed greater sensitivity (p=0.008) (p=0.010), increased (p=0.032). Cold thresholds impaired this (cold, p=0.034; heat, p=0.010), although only (p=0.009). The reported more (p=0.001).Persistent pressure, hyperalgesia, pain.Level III, prognostic study.
