AB  - PURPOSE: Anterior knee pain is a frequent symptom in the osteoarthritic knee. Its 
      intensity has been classically evaluated by the visual analogic score (VAS). The 
      main objective of the study was to assess whether pressure algometry (PA) can be 
      used as a reliable tool to quantify anterior pain in the osteoarthritic knee. 
      METHODS: A prospective study was designed, including 160 patients scheduled for 
      unilateral total knee arthroplasty. Patellar pain and function were evaluated 
      according to a specific patellofemoral pain questionnaire and the Knee Society 
      Score. Patients were asked about their pain at rest, while walking and in the 
      stairs with the VAS score. PA by an algometer was used in the anterior part of 
      the patella to determine the pressure pain threshold (PPT): the minimal pressure 
      when the patient feels a painful sensation. RESULTS: The mean values of PPT were 
      385.1 kPa in the knees going to be operated and 403.4 kPa in the contralateral 
      knees (p < 0.05). The anterior knee pain in the patellar score averaged 6.9, and 
      the total patellar score averaged 15.2. PPT values were correlated with the 
      anterior pain in the patellar score (rho = 0.31, p < 0.001) and also with the total 
      patellar score (rho = 0.33; p < 0.001). CONCLUSIONS: PA demonstrated to be suitable 
      to measure anterior knee pain in the osteoarthritic knee. PA can specifically 
      assess the anterior knee pain better than other methods as VAS score. PA could be 
      used as the main measurement when comparing different treatments for the anterior 
      knee pain caused by osteoarthritis.
