Effectiveness of Bach Nien Kien Health Supplement in the Treatment of Patients With Symptomatic Knee Osteoarthritis.

BACKGROUND/AIM: Knee osteoarthritis (KOA) is the most common disease in adults. We conducted a clinical study to evaluate the efficacy and safety of Bach Nien Kien (BNK) in supportive therapy for patients with symptomatic KOA.

PATIENTS AND METHODS

An open interventional study was performed on 60 patients aged 38 to 70 with the diagnosis of symptomatic KOA. The patients were assigned to a study group (SG) with 30 subjects and a control group (CG) with 30 subjects using a matching method. The patients in SG were treated with electroacupuncture, glucosamine supplement, and BNK, while the patients in CG received the same treatment without BNK.

RESULTS

At the end of the 30-day treatment (d30), the SG had a reduction in VAS score compared to a pre-treatment level of 3.03±0.96 points, which was more than the CG of 2.5±0.90 points. The excellent result in the SG was 10%, and the CG had no excellent result. The good result in the SG was 56.7%, and the CG group was only 26.7%. The moderate and poor results in the CG were high, 63.3%, and 10%, respectively; in the SG, only 26.7% and 6.7%. The difference in overall treatment results between the SG and CG was statistically significant (p<0.05). During the 30-day treatment period in both groups, no patient reported any undesirable effects.

CONCLUSION

Bach Nien Kien health supplement is effective and safe for controlling KOA symptoms and improving joint motion and quality of life for patients with symptomatic KOA.
