Objectives: The evaluation of a successful replacement surgery varies between physicians and patients. Approximately 1 in 5 patients undergoing this type of joint surgery are not satisfied with the result obtained 12 months after their surgery. The aim of this work is to find out the correlation between satisfaction and functionality in patients with either osteoarthritis (OA) or inflammatory joint disease (IJD) who had undergone knee or hip replacement surgery in our institution charity clinic, the satisfaction with program's surgery rate and to the patients' clinical improvement. Methods: This is a prospective cross-sectional study with patients who underwent surgery between 2015 and 2018. The Self-Administered Patient Satisfaction Scale (SAPS) questionnaire was applied at least 12 months after the procedure and correlated to the functional scales Harris hip score (HHS) or Knee Society Score (KSS). Results: The HHS and KSS functional scales had a good and statistically significant correlation with the SAPS of 0.44 (P < 0.001). The program's satisfaction index for surgery had a mean of 95%. Pre- and post-operative assessments (at least 12 months) of the HHS/KSS functional scales obtained an initial median of 39.14 points and a final result of 87 for IJD and 93 for OA with a mean of 90 points (P = 0.000). Conclusions: The correlation between SAPS and the functional scores (HHS/KSS) 0.44 is good/moderate and it is statistically significant. The satisfaction with the program's surgery rate based on SAPS had a mean of 95%. Functionality assessed with HHS/KKS had a mean of 90 points. Using SAPS and HHS/KSS scales, we can conclude that the patients had a favorable clinical outcome. According to SAPS, IJD patients have better satisfaction indices than OA even though they have worst functional end results.
