Introduction: Osteoarthritis (OA) is a chronic joint disease that usually occurs in older people and leads to pain and disabilities. OA treatment ranges from drug therapy to surgery. Drug and rehabilitation therapy are preferred over surgery, and, especially, there is a tendency toward compounds causing regenerative changes in the knee joint. In the present study, the effects of platelet-rich plasma (PRP) injection and prolotherapy (PRL) were examined on the level of pain and function of the knee joint in patients with OA.
Methodology: After fulfilling the inclusion criteria and signing the informed consent form, 42 patients with knee OA were scheduled for intra-articular injection in the present randomized, double-blind, clinical trial. Following admission to the operating pain room, the condition of the patient’s knee was evaluated first via the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and, then, ultrasound-guided knee injection was done. Accordingly, patients in the PRP therapy group received 7 mL PRP solution and those in the PRL group received 7 mL 25% dextrose. Using the WOMAC, levels of pain and knee function were evaluated and recorded for each patient immediately prior to the first injection as well as at 1 month (immediately prior to the second injection), 2 months (a month after the second injection), and 6 months later. Data collected were analyzed using the SPSS v.20.
Results: During the first and second months, a rapid decrease in the overall WOMAC score was observed in both groups. The overall WOMAC score increased at the sixth month, but was lower than the overall WOMAC score in the first month. Statistical analysis indicated that the overall WOMAC score significantly decreased in both groups of patients over 6 months.
Conclusion: Results of the present study suggested a significant decrease in the overall WOMAC score of patients who undergo either PRP therapy or PRL. This positive change in the overall WOMAC score led to an improvement in the quality of life of patients with knee OA shortly after the first injection. PRP injection is more effective than PRL in the treatment of knee OA.

FAQ:

PRP means Platelet Rich Plasma. The Plasma liquid in the blood includes red and white blood cells and platelets. Platelets form 10% of the plasma and in the concept of PRP, the platelet ratio is flipped to 90%. It is given in the form of an injection to patients looking to treat tissue damages, skin issues etc.
A non-surgical therapy in nature, PRP is used for healing in several medicine fields including sports medicines and orthopedics. PRP is nothing but the patient’s own blood which is administered in a way such that the healing components (growth factors) present in the platelets are released, thus fuelling fast recovery.
PRP is majorly useful in cases of soft tissue injuries, including ligament sprains, muscle pulls / tears, tendon tears, tendonitis and tendinosis. It has been an effective way to treat cartilage degeneration like arthritis as well.
With its methodology, PRP is developed to heal the injured region through the initiation of growth factors in your platelets. It is a cure and not just a temporary solution to limit any injury.
In most cases, the procedure can be well tolerated by patients but there may be soreness after the injection as PRP induces
