The optimal approach to treating lateral epicondylitis with PRP injections and the impact of adding shockwave therapy can be summarized as follows:

Optimal Timing and Dosage of PRP Injections:

  1. Dosage: Typically, 3-6 mL of PRP is used per injection, with platelet concentrations 2-3 times higher than normal blood. This concentration balance is crucial for promoting healing without adverse effects.
  2. Timing: Protocols vary, but common approaches include a single injection or multiple injections (2-3) spaced 2-4 weeks apart. The choice may depend on patient response and severity.

Impact of Adding Shockwave Therapy:

  1. Efficacy: Shockwave therapy, which uses high-energy sound waves, may enhance PRP effectiveness by stimulating blood flow and breaking down scar tissue, creating a receptive environment for healing.
  2. Protocol: Typically involves 3-5 sessions, possibly before or after PRP injections. The exact timing and parameters (intensity, frequency) can vary, but it's often used in conjunction with PRP.
  3. Patient Selection: May be more beneficial for chronic cases and influenced by factors like severity, duration, and patient age.

Considerations:

  • Safety: Both treatments are generally safe, with minor side effects like discomfort or bruising.
  • Evidence: Recent studies and clinical guidelines suggest that combining PRP with shockwave therapy can improve outcomes, though individual responses may vary.
  • Research: Ongoing research continues to refine these approaches, so staying updated with the latest clinical guidelines is important.

In conclusion, while PRP injections and shockwave therapy show promise, the optimal approach may need to be tailored to individual patients, considering factors like treatment protocol, patient characteristics, and emerging evidence.
