Tendons connect muscles to bones. They receive limited blood flow, so they can heal slowly after an injury. Repetitive movement and age-related wear can both contribute to tendon damage. When rest and therapy do not resolve tendon pain, providers may discuss orthobiologics, and you ask your questions.
Using Platelet-Rich Plasma
Platelet-rich plasma (PRP) comes from a small sample of your own blood, then a machine spins the blood to concentrate the platelets. Platelets contain growth factors, which are proteins that signal cells to begin repair. PRP has a higher platelet concentration than normal blood, which makes it relevant for tendon injuries. Your orthobiologics provider injects the PRP into the tendon injury, and the procedure usually takes place in a clinic. Before the injection, your provider may use imaging to confirm the location of the damage. Your provider may recommend a follow-up visit to assess progress, and imaging will be used to monitor tissue changes. Mild soreness at the injection site can occur for a few days.
Exploring Stem Cell Therapy
Stem cell therapy uses cells that can develop into different tissue types, so providers usually collect these cells from bone marrow or fat tissue. The collection process typically takes place during a separate outpatient visit. Cells are processed in a lab to concentrate them. The provider then injects them into the damaged tendon using imaging guidance to confirm accurate placement. They may suggest other options first, such as PRP or a structured physical therapy program. Some conditions may make stem cell therapy inappropriate, so your provider will screen for these before proceeding. Before you schedule stem cell therapy, ask about the following:
- Cell collection: Cells are typically drawn from bone marrow or fat tissue during a separate outpatient visit.
- Preparation and injection: Cells are concentrated in a lab, then injected into the tendon using imaging guidance.
- Eligibility factors: Active infection or blood disorders may make this treatment unsuitable for some patients.
- Cost and coverage: Many insurers classify stem cell therapy as experimental; contact your insurer before your appointment to understand out-of-pocket costs.
- Follow-up care: Your provider will schedule visits after the procedure and may use imaging to monitor your tendon’s response over time.
Combining Orthobiologics With Medicine
Injections are one part of tendon care. Physical medicine focuses on restoring movement, strength, and function through guided exercise. Tendons respond to gradual loading, so therapists build exercise plans in stages. Early sessions may focus on gentle range-of-motion work. Your therapist will monitor how your tendon responds before advancing the program. Later sessions add resistance as the tendon tolerates more load. After an injection, your provider may limit activity. Therapy then progresses over several weeks.
When therapy begins after an injection matters, so your care team will coordinate the transition. Your therapist may also use hands-on techniques to reduce stiffness and improve circulation. As strength improves, the program shifts toward functional movements reflecting your daily activities or sport. Your therapist will track your progress and adjust your plan based on your tendon’s response.
Schedule a Tendon Evaluation
Orthobiologics offer options beyond rest and medication. PRP and stem cell therapy use your body’s own materials, and physical medicine supports the recovery process. Note when your pain started and which movements make it worse. Bring a list of past treatments to your appointment. If tendon pain limits your daily activities, ask whether orthobiologics fit your condition.
