In plain language
Platelet-rich plasma (PRP) is a platelet concentrate prepared from the patient’s blood; composition varies with the preparation method.
Clinical Significance & Management
PRP may relieve symptoms in some knee osteoarthritis and tendon conditions. Benefits vary by condition and preparation; evidence for Achilles, patellar and acute muscle injuries remains uncertain.
Clinical uses
Selected knee osteoarthritis or chronic tendon conditions may warrant discussion after assessment.
Conditions and context
- The underlying diagnosis, previous treatment response and patient goals guide consideration.
Diagnostics & Imaging Guide
Confirm diagnosis and review medication, bleeding and infection risks; select imaging and guidance as clinically needed.
Treatment Options
Discuss benefits, limitations and alternatives before injection; formulation and injection schedules are not standardized across conditions.
Rehabilitation Milestones & Timeline
Rehabilitation depends on the diagnosis, procedure and associated injuries. Progression requires assessment of healing, symptoms and function; elapsed time or a single test cannot determine readiness for sport.
Rehabilitation context and progression
Adjust activity to the injection response and underlying condition, then reload gradually. Discuss analgesic and anti-inflammatory use with the clinician; do not stop prescribed medicines independently. Worsening pain needs reassessment.
Evidence-Based Clarifications
PRP is not a stem-cell product and cannot guarantee cartilage regeneration. Autologous blood does not eliminate injection risks such as infection, bleeding, pain or tissue injury.
