Abstract
Objective
To compare the effectiveness of prolotherapy with dextrose concentrations of 5%, 10%, and 20% in patients diagnosed with knee osteoarthritis.
Methods
This study was planned as a prospective, randomized controlled interventional trial. Prolotherapy at 5% dextrose concentration in group 1, 10% in group 2, and 20% in group 3 was applied to the knee intra-articularly and periarticularly at 0, 3, and 6 weeks, and a home exercise program was given. Group 4 received a home exercise program. All groups received hotpack therapy at weeks 0, 3, and 6. Outcome measures included the visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee range of motion, timed up and go test, and Short Form-36.
Results
A total of 128 patients were divided into 4 groups. At the 6th and 12th weeks, VAS scores were significantly lower in groups 2 and 3 than in group 4 (p < 0.05). At the 12th week, the WOMAC pain score was significantly lower in group 3 than in group 4, and WOMAC physical function and WOMAC total scores were significantly lower in groups 1, 2, and 3 than in group 4 (p < 0.05). Week 6 active and passive knee flexion and week 12 passive knee flexion were significantly higher in group 3 than in group 4 (p < 0.05).
Conclusions
Although no significant difference was observed among the dextrose prolotherapy groups, higher dextrose concentrations demonstrated a greater improvement compared to the control group. Therefore, the use of 20% dextrose is recommended due to its significant superiority. Long-term follow-up and placebo-controlled studies are needed.
Trial registration
ClinicalTrial.gov Identifier: NCT05537077, registration date: 09.03.2022, retrospectively registered.
Key Points • The utilization of dextrose prolotherapy has gained popularity in the management of osteoarthritis, aiming to harness its regenerative and proliferative properties. However, the comparative efficacy of various concentrations of dextrose prolotherapy in treating knee osteoarthritis remains unexplored in the literature. This study aimed to address this gap by comparing different concentrations of dextrose prolotherapy in the treatment of knee osteoarthritis. The findings revealed no statistically significant difference among the various concentrations of dextrose prolotherapy for knee osteoarthritis treatment. |
