Ultrasound-guided knee injection is a knee injection performed while the clinician watches a live ultrasound image. It is used to place a needle into a specific knee space or tissue with visual confirmation. It is commonly performed in orthopedics, sports medicine, rheumatology, and pain-focused musculoskeletal care. It may be used for diagnosis (to localize pain) or treatment (to deliver medication or biologic material).

RFA genicular nerves is a pain procedure that targets small sensory nerves around the knee. It uses radiofrequency energy to reduce pain signals traveling from the knee to the brain. It is most commonly discussed for chronic knee pain, especially when arthritis is involved. It is typically performed in interventional pain, sports medicine, or orthopedic care pathways.

Genicular nerve radiofrequency ablation is a minimally invasive pain procedure for the knee. It uses controlled radiofrequency energy to reduce pain signals carried by small nerves around the joint. It is most commonly discussed for knee osteoarthritis pain and persistent knee pain when surgery is not preferred or is being delayed. It is performed by clinicians trained in image-guided pain procedures, often in outpatient settings.

Genicular nerve block is an injection-based pain procedure that targets small nerves that carry pain signals from the knee joint. It is commonly used to help clarify where knee pain is coming from and to reduce pain for a period of time. It is often discussed in the setting of knee osteoarthritis, chronic knee pain, or pain after knee surgery.

Prolotherapy knee is an injection-based treatment used to address certain types of knee pain and perceived joint instability. It most commonly involves injecting an irritant solution (often hypertonic dextrose) around or within the knee. It is used in outpatient settings by some sports medicine, orthopedic, and pain-focused clinicians. It is generally discussed as a “regenerative” or “stimulatory” injection approach, although results vary.

Stem cell injection knee is a type of orthopedic injection that aims to support a painful or injured knee joint. It usually involves placing a patient-derived “cell-rich” or “biologic” preparation into the knee, most often into the joint space. It is commonly discussed in the context of knee osteoarthritis, cartilage wear, and some soft-tissue problems around the knee. The exact product, processing, and technique vary by clinician and case.

BMAC injection knee refers to injecting bone marrow aspirate concentrate (BMAC) into or around the knee joint. BMAC is made from a person’s own bone marrow that is collected and concentrated on the same day. It is commonly discussed in orthopedics and sports medicine as a “biologic” treatment option for certain knee conditions. Clinicians may use it as a non-surgical option or as an adjunct to a surgical procedure, depending on the case.

Platelet-rich plasma is a concentrated portion of a person’s own blood that contains a higher-than-usual number of platelets. Platelets release signaling proteins that can influence inflammation and tissue repair. In orthopedics and sports medicine, it is commonly used as an injection for tendon, ligament, muscle, and joint problems. It is also discussed in knee care for conditions like tendinopathy and some forms of osteoarthritis.

PRP injection knee is a treatment that uses a concentrated portion of a person’s own blood called platelet-rich plasma (PRP). It is injected into or around the knee to support healing and symptom management in selected conditions. It is commonly discussed in sports medicine and orthopedics for knee pain related to overuse injuries or arthritis. It is considered an “orthobiologic” approach because it uses biologic material to influence joint and tissue health.

Durolane injection is an intra-articular injection of hyaluronic acid (HA) used to support joint lubrication. It is most commonly discussed in the context of knee osteoarthritis-related pain and stiffness. It is a type of “viscosupplementation,” meaning it aims to supplement the joint’s natural fluid properties. This overview is informational and does not replace evaluation by a licensed clinician.
