Knee Joint Injections — Targeted Relief for Knee Pain and Stiffness
Knee joint injections offer a minimally invasive way to reduce pain, ease inflammation and improve mobility when knee symptoms start affecting daily activities. They are commonly used when medication, rest or physiotherapy have not provided enough relief. At Total Pain Specialist, our anaesthetist uses precise, ultrasound-guided techniques to ensure the medication reaches the exact part of the knee responsible for your symptoms, supporting safer and more effective treatment.
What are knee joint injections?
Knee joint injections are minimally invasive procedures where medication is placed directly into the part of the knee responsible for pain, stiffness or swelling. These injections can target the main knee joint, the surrounding soft tissues, or specific areas such as the joint lining or inflamed bursae. At Total Pain Specialist, ultrasound guidance is used to ensure accurate placement of the needle, allowing the medication to reach the exact structure that needs treatment. This approach helps reduce inflammation, improve comfort and support better knee movement, particularly when symptoms have not improved with rest, physiotherapy or oral medication.
Why consider knee joint injections?
Knee joint injections provide targeted relief when pain or stiffness begins to interfere with walking, exercise or daily activities. They are useful when conservative treatments have not been enough.
Benefits include:
- Reduced inflammation in the joint
- Improved mobility and easier movement
- Less pain during activity
- Support for rehabilitation when combined with physiotherapy
- Delay or avoidance of surgery in suitable cases
- More accurate treatment when done under ultrasound guidance
What conditions can knee joint injections treat?
Knee joint injections are commonly used to manage a range of orthopaedic and pain-related knee conditions, especially when symptoms persist despite conservative treatment.
- Osteoarthritis — knee osteoarthritis occurs when the protective cartilage covering the joint surfaces wears down over time. This leads to pain, stiffness and reduced mobility, especially during weight-bearing activities.
- Rheumatoid arthritis — rheumatoid arthritis is an autoimmune condition that causes inflammation of the joint lining (synovium). When it affects the knee, it can result in swelling, warmth, pain and progressive joint damage if untreated.
- Bursitis — bursitis involves inflammation of the bursae, small, fluid-filled sacs that reduce friction around the knee. Swelling and tenderness may occur, particularly around the front or inner side of the knee.
- Tendinitis — knee tendinitis occurs when tendons such as the patellar or quadriceps tendon become irritated or inflamed, causing pain during movement and limiting knee strength and function.
- Meniscal degeneration or irritation — age-related wear or minor tears in the meniscus may cause knee pain, swelling and mechanical symptoms that respond to targeted injections.
- Post-injury inflammation — persistent swelling or irritation after sprains, strains or overuse injuries may improve with image-guided injections.
Types of knee joint injections offered
Different types of injections can be used depending on the source of knee pain and your specific condition.
- Steroid injections — these injections reduce inflammation inside the knee joint, helping to ease pain and swelling for short- to medium-term relief.
- Hyaluronic acid injections — a gel-like substance is injected into the joint to improve lubrication, reduce friction and support smoother movement in knee osteoarthritis.
- Regenerative injections (PRP) — PRP uses a patient’s own platelets to support tissue repair and reduce pain in damaged tendons, muscles and ligaments.
- Nerve blocks — medication is placed near specific nerves around the knee to reduce pain signals when symptoms are nerve-related.
- USG-guided injections — ultrasound guidance is used to place the needle accurately at the targeted knee structure, improving precision and overall treatment effectiveness.
How are knee joint injections performed?
At Total Pain Specialist, knee joint injections are carried out in a simple, structured manner to ensure accuracy and comfort.
- Positioning — you will be placed comfortably on the procedure table so the knee can be accessed easily.
- Skin cleaning — the injection site is thoroughly cleaned with an antiseptic solution to reduce infection risk.
- Local anaesthetic — a small amount of numbing medication is applied to minimise discomfort.
- Ultrasound guidance — our anaesthetist uses real-time ultrasound imaging to guide the needle precisely to the targeted area within the knee.
- Medication delivery — the selected medication is injected into the joint space or surrounding inflamed tissue.
- Final cleaning and dressing — the needle is removed, the area is cleaned again, and a small dressing is applied.
Most injections take only a few minutes and involve minimal discomfort.
Are knee joint injections painful?
Knee joint injections are generally well tolerated. A small amount of local anaesthetic may be used to reduce discomfort at the injection site. You may feel brief pressure as the needle enters the joint, but the procedure is typically completed within a short time. Any post-procedure soreness is usually mild and temporary.
Recovery and aftercare
Most patients are able to resume normal daily activities shortly after a knee joint injection. Mild soreness at the injection site may occur but generally settles within a day or two. It is advisable to avoid strenuous exercise or high-impact activities for a short period as recommended by our anaesthetist. Depending on your condition, additional measures such as physiotherapy, strengthening exercises or activity modification may be suggested to support longer-term improvement.
Possible side effects of knee joint injections
Knee joint injections are generally safe, and most side effects are mild and temporary. These may include:
- Soreness or swelling at the injection site
- Mild bruising
- A temporary increase in discomfort before the medication takes effect
Less common risks include:
- Infection at the injection site
- Allergic reaction to the medication
- Bleeding, especially in patients on blood-thinning medication
Our anaesthetist will review your medical history and discuss any specific considerations before the procedure.
Summary
Knee joint injections provide a minimally invasive option for managing persistent knee pain when symptoms interfere with daily movement or do not improve with conservative treatment. By placing medication directly at the structures involved in pain and inflammation, these injections can support improved comfort and mobility. Ultrasound guidance enhances accuracy and helps ensure that the treatment is delivered to the intended area. For suitable patients, knee joint injections can play an important role in reducing symptoms and supporting overall function.
If you have been experiencing ongoing knee pain and would like to know whether knee joint injections may be appropriate for your condition, you may schedule a consultation with Total Pain Specialist for further assessment and guidance.
Frequently Asked Questions
Relief from knee joint injections may begin within a few days, although some patients notice improvement over one to two weeks as inflammation settles.
The duration varies depending on the condition and type of medication used. Some patients benefit for several weeks, while others experience longer-lasting relief.
Yes. Knee joint injections are commonly used for osteoarthritis and can help reduce pain and stiffness when conservative measures are not enough.
Most patients can walk right after the procedure, though strenuous or high-impact activities should be avoided temporarily as advised.
The recommended number depends on the type of injection and your clinical condition. This will be determined during consultation.
Ultrasound may be used to assess the knee and guide knee joint injections accurately to the targeted structure.
In some cases, knee joint injections can help manage symptoms and postpone surgery, depending on the severity of joint degeneration.
