Joint injections are treatments used to reduce pain, swelling and stiffness in joints such as the knee, shoulder, hip or elbow.
Overview
What are joint injections?
Joint injections are treatments used to reduce pain, swelling and stiffness in joints such as the knee, shoulder, hip or elbow.
The two common types are:
- Steroid injections: Reduce inflammation and pain quickly
- PRP (platelet-rich plasma) injections: Use a person’s own blood to support healing and tissue repair
These injections are commonly used for arthritis, sports injuries and tendon problems.
Common conditions leading to the surgery
- Osteoarthritis (wear-and-tear arthritis)
- Tendon injuries
- Frozen shoulder
- Tennis elbow
- Knee pain due to cartilage damage
- Joint inflammation or swelling
When is surgery required?
Surgery may be considered when:
- Joint damage is severe
- Pain does not improve with injections or medicines
- Walking or movement becomes very difficult
- Joint function is badly affected
Examples include knee replacement or shoulder surgery.
