For a shoulder labral tear, steroid injections offer rapid, temporary pain relief, while platelet-rich plasma (PRP) injections promote long-term healing and functional improvement by addressing the underlying tissue damage. The best choice depends on treatment goals, injury severity, and the patient's overall health.
Steroid Injections
- Mechanism: Steroids are potent anti-inflammatory medications that reduce swelling and pain, but they do not repair damaged tissue.
Benefits:
- Provide quick, often immediate, pain relief (within days).
- Improve short-term function and range of motion, which can aid initial physical therapy efforts.
Risks & Considerations:
- Relief is typically temporary, lasting a few weeks to several months, and symptoms often recur.
- Repeated injections can weaken tendons and cartilage over time, increasing the risk of further damage or rupture.
- May increase blood sugar levels temporarily in patients with diabetes.
- Can compromise healing if surgery is needed later, especially if administered within a few months of the operation.
Platelet-Rich Plasma (PRP) Injections
- Mechanism: PRP uses the patient's own concentrated platelets and growth factors to stimulate the body's natural healing processes and promote tissue regeneration. It works by creating a controlled inflammatory response to start the repair cascade.
Benefits:
- Promotes long-term functional improvement and sustained pain relief by addressing the root cause of the injury.
- Studies suggest it may lead to a reduction in tear size in partial tears and improve long-term functional scores compared to steroids.
- Carries a very low risk of allergic reaction or transmissible infection since it uses the patient's own blood.
- May help patients avoid surgery in some cases of partial labral or rotator cuff tears.
Risks & Considerations:
- Initial pain relief takes longer to manifest, usually a few weeks to months, as the healing process takes time.
- May cause temporary soreness or stiffness at the injection site.
- Not always covered by insurance and can be costly.
- Efficacy can vary depending on the severity of the tear and the specific PRP preparation used.
