Skin Sensitivity to Pressure and Kneeling Ability Before and After TKA

The kneeling ability and sensitivity to pain tested in 30 consecutive patients undergoing primary TKAs, Thirty (30) knees (16 right, 14 left). Kneeling difficulties following TKA were noticed in the majority of patients. Before surgery, the PPTs (Pain Pressure Thresholds) measures were lower in the patients who were unable to kneel compared to those who were able to kneel. However, this difference was not significant at QT (Quadriceps Tendon) area (p=0.2) but significant in all other areas (P= < 0.05). At 6 months the values were changed but again the differences were not significant (p=> 0.05). There were notable gender differences in the kneeling ability before and after TKA.
