Background Osteoarthritis is a major burden worldwide.

Objectives Arthritic conditions are extremely painful for the patient and are associated with a significant reduction in health related quality of life (HRQOL), mainly in term of physical and functional impairment. Therefore, the demand for total joint replacement (TJR) is increasing. The objective of the present study was to access the radiological and clinical profil of osteoarthritic patients undergoing of total joint replacement.

Methods We analyzed the preoperative radiologic and clinical status of 185 consecutive patients undergoing total joint replacement for symptomatic osteoarthritis of the lower limb.

Specific HRQOL was assessed with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the pain with the EQ-VAS. These questionnaires were administered preoperatively.

Results Our cohort included 75 men and 110 women aged from 33 to 86 years (mean 65.2±10.5). 102 of them received a total hip prosthesis and 83 of them a total knee prosthesis.

The mean duration of OA was 3097.2±3281.5 (SD) days or 8,5±9 years

They were all diagnosed with primary OA following the ACR criteria.

172 pre-operative X-ray assessments were available and analyzed. Out of the 172, 2,9% (n=5) were presenting with a KL-score of 1; 39,5% (n=68) were presenting with a KL-score of 2; 39,5% (n=68) with a KL-score of 3 and 18% (n=31) with a KL-score of 4.

The mean value EQ-VAS pain was 62.4 (mean) ±17.2 (SD).

The mean WOMAC score values were 10.8±3.8 for pain, 4.6±1.8 for stiffness, 36.1±13 for physical function. The total WOMAC score was 51.4±17.2 (0-96).

Conclusions We concluded that patients undergoing total joint replacement in university setting, in Belgium, do present with a moderate to severe OA.
