Joint injections offer a targeted approach to managing joint pain and avoiding the drawbacks of other medications. Injecting pain medications directly into an affected joint can help diminish inflammation and alleviate pain.
The injection often combines a steroid medication (to reduce inflammation) with an anesthetic (to numb the area for immediate pain relief). This combination treats various joint conditions and can help patients improve their range of motion and participate in physical therapy.

Types of Joint Injections
The landscape of joint injection procedures encompasses a range of techniques differentiated by the substances injected and the diseases they target. The choice of procedure depends on a patient’s specific medical condition, pain severity, and overall health profile.
Understanding the diversity of these injections empowers patients to discuss with their pain doctor the most suitable option for their unique situation. There are several types of joint injections available for managing painful joints, each with distinct characteristics:
- Corticosteroid Injections.
- Hyaluronic Acid Injections.
- Platelet-Rich Plasma (PRP) Injections.
- Prolotherapy.
- Stem Cell Injections.
Each injection type offers unique advantages and may be recommended based on the diagnosis, degree of joint damage, and patient preference.
Corticosteroid Injections
Perhaps the most common joint injection is a cortisone shot, a frequent inflammation remedy that delivers potent corticosteroids directly to an affected joint. These injections commonly contain a powerful steroid to reduce inflammation. They are particularly effective for conditions like rheumatoid arthritis, bursitis, and various types of allergy-related joint discomfort.
Despite their ability to provide relatively rapid relief, cortisone injections are limited in the frequency of their use due to potential side effects, including joint cartilage degradation over time and suppression of the body’s cortisol production. Therefore, they are carefully administered, usually alongside a local anesthetic, to manage the pain while minimizing risks.
Hyaluronic Acid Injections
Hyaluronic acid injections are designed for osteoarthritis patients. The injection lubricates the joint, mimicking the naturally occurring synovial fluid. These injections, mainly applied in the knees, aim to restore the viscous properties of the joint fluid, thereby reducing friction and wear on the cartilage.
While not an immediate pain reliever like cortisone, hyaluronic acid injections can offer sustained pain management and improved mobility over a longer period. The injection is best suited for patients with chronic knee osteoarthritis seeking a non-surgical method to manage their joint pain effectively.
Platelet-Rich Plasma (PRP) Injections
Platelet-rich plasma (PRP) injections are an innovative and non-surgical method that harnesses your body’s innate healing processes to expedite recovery and diminish discomfort. PRP is created by processing your blood to boost the concentration of platelets, which are the cells responsible for clotting and tissue regeneration. The concentrated solution is then injected into the injured or damaged joint.
The science behind PRP injections is rooted in the body’s remarkable ability to heal itself. The high concentration of growth factors in PRP stimulates tissue regeneration, reduces inflammation, and promotes faster healing. Platelets, when injected into injured tissue, help promote new tissue growth. The process can significantly improve joint function, reduce pain, and enhance overall quality of life.
Prolotherapy
Prolotherapy, also known as regenerative injection therapy, involves injecting a solution, typically a mixture of dextrose (sugar water) and a local anesthetic, into the affected area. The solution acts as an irritant, triggering a mild inflammatory response that initiates the healing process.
Prolotherapy injections promote the growth of new collagen, which is essential for strengthening connective tissue. The treatment can help strengthen and tighten injured ligaments and tendons, improving joint stability and reducing pain.
Stem Cell Injections
Stem cell injections harness the regenerative power of stem cells to repair and restore damaged tissues. Stem cells harvested from the patient’s bone marrow or fat tissue are injected into the joint to help regenerate damaged tissues within the joint. When injected, stem cells can help reduce inflammation, promote tissue repair, and potentially regenerate damaged cartilage.
The science behind stem cell injections lies in their remarkable capacity for self-renewal and differentiation. When injected into injured or diseased tissue, stem cells can migrate to the site of damage and transform into the specific cell types needed for repair. This regenerative process can help reduce pain, improve mobility, and enhance tissue function.
What’s in a Joint Injection?
Joint injections typically contain medications to alleviate pain and inflammation within the affected joint. Corticosteroids are a mainstay in joint injection therapy due to their potent anti-inflammatory properties.
Another common ingredient is hyaluronic acid, which acts as a lubricant and shock absorber, helping to ease joint movement in patients with conditions such as osteoarthritis. Some injections may also contain local anesthetics to provide immediate pain relief during and after the procedure.
Innovations in treatment include biologics like platelet-rich plasma (PRP) and stem cell therapies, which utilize the body’s natural healing agents to regenerate damaged tissues. PRP injections tap into the healing power of platelets, which contain proteins known as growth factors crucial for tissue recovery and repair. These are particularly beneficial in conditions like tendinopathy.
The Joint Injection Process
Initially, the patient undergoes a thorough evaluation to determine the appropriateness of the injection for their condition. Once approved, the clinician cleans the targeted area with an antiseptic solution. A local anesthetic numbs the site to minimize discomfort.
Utilizing advanced imaging techniques like X-ray or ultrasound, and often with the assistance of fluoroscopy for real-time guidance, the physician expertly guides the needle into the precise joint space. The selected medication is gently injected to ensure the patient’s comfort and the treatment’s effectiveness.
The total time from preparation to the completion of the injection process usually lasts between 10 to 30 minutes, including the necessary post-procedure observation for any immediate adverse reactions.
When Should You Consider Joint Injections?
Good candidates for joint injection typically include those who endure persistent joint pain that has not responded to conservative treatment methods such as oral medications or physical therapy. Ideal candidates are those with inflammatory joint conditions like rheumatoid arthritis, degenerative diseases such as osteoarthritis, or sports-related injuries.
The pain doctor assesses the extent of joint damage, the level of pain, functional limitations, and the patient’s overall health status to determine their suitability for the injection. Candidates for joint injections must have realistic expectations of the results and understand the potential risks and benefits.
Which Joint Areas Benefit Most from an Injection?
Joint injections are tailored to provide relief in various parts of the body, with the ankle joint and sacroiliac joint being common focal points for treatment. The American College of Rheumatology highlights that larger joints such as knees, hips, shoulders, elbows, and wrists often respond favorably to joint injections, including corticosteroid injections, for conditions like arthritis.
The knees benefit significantly from the lubricating effect of hyaluronic acid injections, especially where osteoarthritis is present. Smaller joints in the hands and feet, while trickier due to their intricate structure, may still benefit from precisely administered injections. For instance, the ankle can receive targeted treatment to relieve persistent pain from conditions like osteoarthritis or tendon injuries.
Side Effects and Safety Measures
Joint injections, including those targeting the spine and other joints, are generally considered safe; however, complications, although rare, may arise from needle insertion, including bleeding, infection, and allergic reactions.
Repeated corticosteroid injections could potentially lead to joint cartilage deterioration and tendon weakening. For individuals wanting to avoid steroid risks, alternative therapies such as hyaluronic acid injections can cause less systemic side effects; however, they may still cause local reactions such as pain, swelling, and stiffness at the injection site.
Patients with pre-existing conditions like uncontrolled diabetes or those on anti-clotting medication need to approach joint injections with caution due to elevated risks related to blood sugar fluctuations and bleeding. A risk assessment is crucial before proceeding with joint injection treatment.
Post-Injection
Adhering to post-injection protocols after a joint injection is critical to maximize safety and enhance the effectiveness of the treatment. Patients are usually advised to rest the treated joint and avoid strenuous activities for a certain period, typically 24-48 hours.
Applying ice can help manage any injection site soreness and swelling. Monitoring for signs of infection or adverse reactions is crucial; patients should report any unusual symptoms to their doctor immediately. Follow-up appointments are often scheduled to assess the outcome of the injection and to plan further treatment if necessary.
