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.

Monovisc injection is a single-dose joint injection used for certain kinds of knee pain. It contains hyaluronic acid, a substance found naturally in joint fluid. It is most commonly used in people with knee osteoarthritis. Clinicians use it as a non-surgical option to help improve comfort and function.

Synvisc injection is a type of viscosupplementation used to treat joint pain, most commonly in the knee. It contains a hyaluronan-based gel designed to supplement the joint’s natural lubricating fluid. It is typically used for osteoarthritis-related knee pain when simpler treatments have not been enough. It is given as an in-office injection into the knee joint space by a trained clinician.

Viscosupplementation is an injection treatment used for painful joints, most commonly the knee. It typically involves injecting hyaluronic acid into the joint space to improve lubrication. It is most often discussed in the context of knee osteoarthritis and mechanical joint pain. Clinicians may consider it when other non-surgical options have not provided enough relief.
