Stem Cell Therapy is a treatment concept that uses living cells with regenerative and immunomodulatory potential. Stem Cell Therapy is best classified as a **procedure and biologic intervention**, not a single standardized product. In musculoskeletal practice, it is most often discussed for **degenerative joint disease** and **tendon/ligament conditions**. It is also referenced in orthopedic research and sports medicine as a potential tool for tissue repair.

PRP Therapy is a treatment that uses a patient’s own blood components to create a platelet-concentrated injectate. It is best categorized as a procedure and biologic injection technique rather than a medication. It is commonly used in orthopedics and sports medicine for selected tendon, ligament, muscle, and joint conditions. It is discussed as an adjunct to rehabilitation, not a replacement for diagnosis and staged care.

Platelet Rich Plasma is an autologous biologic product made from a patient’s blood with a higher-than-baseline platelet concentration. It is a **concept and procedure** used as an injection-based treatment in musculoskeletal and sports medicine. It is most commonly discussed in outpatient orthopedics for tendon, ligament, muscle, and joint-related pain syndromes. Clinicians use it as a way to deliver platelet-associated signaling molecules to a targeted tissue site.

Hyaluronic Acid Injection is an intra-articular injection that delivers hyaluronic acid into a joint space. It is a **procedure** used to manage symptoms from certain joint conditions, most commonly osteoarthritis. In practice, it is often discussed as **viscosupplementation**, aiming to improve joint lubrication and mechanics. It is most commonly performed in the knee, with selected use in other synovial joints.

Steroid Injection is a procedure that delivers a corticosteroid medication into or near a painful musculoskeletal structure. It is used to reduce inflammation and improve symptoms in selected orthopedic and sports-medicine conditions. It is most commonly performed in joints, bursae, tendon sheaths, and around the spine or nerve roots. It is a common outpatient intervention in orthopedic clinics, primary care, pain medicine, and rehabilitation settings.

Antibiotic Prophylaxis means giving an antibiotic to reduce the chance of an infection before it starts. It is a clinical concept and preventive strategy, not a diagnosis or an imaging test. In orthopedics, it is most commonly used around surgery, fractures, and implanted devices. The goal is risk reduction during predictable periods of bacterial exposure.

Surgical Site Infection is an infection that occurs in the area of the body where surgery was performed. It is a postoperative complication and a clinical condition used in surgical and hospital medicine. It is commonly discussed after orthopedic procedures involving bone, joints, implants, and soft tissue. It is identified through clinical assessment, wound evaluation, and targeted diagnostic testing.

Postoperative Care is the coordinated medical and rehabilitative management that occurs after a surgical procedure. It is a clinical concept (not a single test or device) that includes monitoring, complication prevention, pain control, wound care, and functional recovery. In orthopedics, Postoperative Care is used after fracture fixation, joint replacement, arthroscopy, tendon/ligament repair, and spine surgery. It is commonly delivered across settings, including recovery units, inpatient wards, outpatient clinics, and rehabilitation services.

Preoperative Planning is the structured process of preparing for a surgical procedure before entering the operating room. It is a clinical concept used to match a patient’s anatomy and goals to an appropriate operative strategy. In orthopedics, it commonly integrates history, physical exam findings, imaging, and implant or fixation selection. It is used across trauma, sports, spine, arthroplasty, and tumor care to improve procedural organization and safety.

Orthopedic Consultation is a structured clinical evaluation focused on bones, joints, muscles, tendons, ligaments, and related nerves. It is a clinical concept and encounter type rather than a single test, device, or operation. It is used to clarify diagnosis, assess function, and plan management for musculoskeletal symptoms or injuries. It commonly occurs in outpatient clinics, emergency departments, inpatient wards, and preoperative settings.
