Joint infiltration is the precise, image-guided delivery of a regenerative or biologic substance directly into the joint capsule — knee, hip, shoulder, ankle, facet, sacroiliac, or small joints of the hand and foot. The technique sounds simple. Done well, it is not: the difference between a needle that lands inside the synovial cavity and one that deposits the product in surrounding fat or capsule is the difference between a real response and a wasted treatment. At Regeneris Therapy every joint infiltration is performed under ultrasound or fluoroscopic guidance by physicians trained in interventional musculoskeletal medicine. We deliver mesenchymal stem cells, PRP, hyaluronic acid, or medical ozone — sometimes in combination — and we are honest about what an intra-articular injection can and cannot accomplish. Here is the plain-language explanation.
What joint infiltration actually is
Joint infiltration — also called intra-articular injection — is the targeted introduction of a therapeutic substance into the synovial cavity of a joint. Every joint has a closed capsule lined with synovial membrane that secretes synovial fluid; this is the space we are aiming for. When the needle is placed correctly, the injected substance distributes throughout the joint surfaces, the synovium, and the immediate sub-synovial tissue — exactly the compartments where degenerative or inflammatory processes are occurring. When the needle misses the cavity and lands in fat, ligament, or capsule, almost none of the product reaches its target. That is why image guidance is not optional in modern practice. Joint infiltration is performed routinely on the knee, hip, glenohumeral (shoulder), acromioclavicular, ankle, subtalar, facet (spinal) joints, sacroiliac joints, and the smaller joints of the hand, wrist, and foot. Each location has its own anatomical considerations and its own ideal approach.
Substances we deliver: MSC, PRP, hyaluronic acid, medical ozone
Our intra-articular menu is tailored to the indication. Mesenchymal stem cells from licensed COFEPRIS-registered laboratories (Wharton's jelly UC-MSC) or prepared chairside as autologous BMAC or SVF are reserved for moderate degenerative disease where regenerative signaling is the goal — see stem cell therapy. Platelet-rich plasma drawn and processed the same day is our workhorse for mild-to-moderate joint OA, partial cartilage lesions, and adjunctive use with MSC — details on PRP therapy. Hyaluronic acid (viscosupplementation) restores synovial fluid viscosity and is useful for symptomatic relief in knee OA, particularly when patients want a less expensive option before stepping up to biologics. Medical ozone (oxygen-ozone gas mixture) has anti-inflammatory and oxidative-stress-modulating effects and is used as a low-cost adjunct in selected indications. We do not push the most expensive product. We match the substance to your case and explain why.
