Objective: The aim of this study was to evaluate the effect of intraarticular injection of sodium hyaluronate through spectral analysis of auscultation.
Materials and Methods: Twenty patients with oseteoarthritis were enrolled. Each subjects were seated on a chair and active knee flexion and extension were ensued for 60 seconds at a speed of 0.5 Hz. Electronic stethoscope and electrogoniometer were applied during the knee motion for data collection. Joint sound data were sampled at 60 kHz and stored in a computer. Analog to digital translation were used and spectral distribution was calculated. Each subjects were repeated by same method in standing position. And then, we compared these data between pre-injection and at post- injection 0, 4 weeks. Changes of activities of daily living were assessed by lower extremity functional scale. Improvement of the subjective pain is recorded by visual analogue scale.
Results: The average of amplitude at sitting position was significantly decreased at post-injection 0, 4 weeks compared with pre-injection status (p£¼0.01). Lower extremity functional scale is significantly increased and visual analogue scale is significantly decreased at post- injection 0, 4 weeks compared with pre-injection status (p£¼0.01).
Conclusion: These results suggest that knee joint sound might be analyzed to evaluate the effect of intraarticular injection of sodium hyaluronate.
