.A knee joint injection is a treatment that helps reduce pain and inflammation by delivering medication directly into the joint. It’s often used for arthritis, where the knee feels stiff, swollen, or painful.

During the procedure, you’ll be lying down comfortably. The skin is cleaned, and a local anesthetic may be applied. Using ultrasound or X-ray guidance, the doctor carefully places a needle directly into the joint for accuracy.

Different medications may be used:

Corticosteroids reduce inflammation, but effects are temporary, and repeated use may weaken the joint. Hyaluronic acid improves joint lubrication in osteoarthritis. Platelet-Rich Plasma (PRP) uses your body's healing factors to repair tissues and reduce inflammation. Research shows that for KL grade 2 or 3 osteoarthritis, PRP at doses of 10 billion or more platelets may provide pain relief and improved function for up to 18 months. Bone Marrow Aspirate Concentrate (BMAC) contains stem cells that may help regenerate damaged cartilage and slow disease progression. Microfragmented Fat (M-Fat) is another regenerative option that uses your own fat cells, which have anti-inflammatory properties and may help cushion and protect the joint. After the injection, you may have mild swelling or discomfort for a day or two. Applying ice packs and resting the knee can help. Avoid strenuous activities for 24 to 48 hours for the best results.

Risks are rare but include infection, bleeding, or temporary pain flares. Your doctor may ask you to pause certain medications, like blood thinners, before the procedure.

If injections alone aren’t enough, physical therapy, medications, or surgery may be considered. Understanding your options is key, and we’re here to help.

If knee pain is limiting your daily life, ask the medical team if PRP, BMAC, M-Fat, or another knee injection could be right for you.
