The focus of today’s discussion is joint issues. In this segment Dr. Grove highlights the importance of assessing not only joints but also surrounding tissues, such as ligaments, muscles, and tendons, when diagnosing joint problems. He emphasizes the value of musculoskeletal ultrasound for accurate, high-definition imaging, which can help differentiate between joint and soft tissue issues like tendon tears. A thorough evaluation is essential for successful recovery and avoiding unnecessary surgeries.

Welcome to Living Pain-Free with Dr. Marc Darrow, MD, and Dr. Thomas Grove, from the Stem Cell Institute in West Los Angeles. This program offers effective solutions for persistent pain. Dr. Darrow is a board-certified medical doctor trained at UCLA. He employs stem cell and platelet-rich plasma therapies to support healing and teaches about the use of stem cells, PRP, and prolotherapy. Dr. Grove is a regenerative medicine specialist with expertise in ultrasound-guided injections and has extensive experience as an athlete and strength and conditioning coach.
Dr. Thomas Grove welcomes listeners back to the weekly show, focused on sports medicine and musculoskeletal health. As a board-certified, fellowship-trained sports medicine physician, Dr. Grove’s passion is helping people become active again. Regenerative medicine is one of his favorite tools, used to heal musculoskeletal issues such as tendon, ligament, joint, or cartilage problems. By concentrating the body’s healing cells and using image guidance for targeted injections, the healing process is promoted as needed.
A joint is formed where two bones meet and glide over one another; the human body contains around 360 joints. Joints are classified based on their mobility:
- Movable joints (Synovial joints):
- Pivot joints: Allow rotation around a single axis (e.g., neck, forearm).
- Hinge joints: Move in one direction, like door hinges (e.g., elbow, knee).
- Condyloid joints: Enable movement in two planes (e.g., wrist, jaw).
- Ball and socket joints: Allow movement in multiple directions (e.g., shoulder, hip).
- Saddle joints: Permit angular movement in several directions (e.g., base of the thumb).
- Plane/gliding joints: Flat surfaces glide over each other (e.g., ankle).
Less movable joints:
Fibrous joints: Held together by fibrous tissue (e.g., skull sutures).
Cartilaginous joints: Allow limited movement, connected by cartilage (e.g., vertebral discs, pubic symphysis).
Diagnosing Joint Pain
When diagnosing joint issues, it’s crucial to examine not only the joint itself but also the surrounding structures. The joint capsule, ligaments, muscles, and tendons all play roles in joint movement and stability. Accurate diagnosis often requires a hands-on physical exam and imaging such as musculoskeletal ultrasound, which offers high-definition views of soft tissue structures and cartilage, sometimes surpassing MRI in detail.
Knee issues are common, and sometimes pain attributed to arthritis may actually stem from problems with surrounding tendons or muscles. For example, quadriceps tendon tears can mimic knee joint pain. Musculoskeletal ultrasound helps pinpoint the exact source of pain and assess joint health.
Common Joint Issues and Treatments
Joint swelling may indicate excess fluid, known as joint effusion. Aspiration (removal of fluid with a needle) can relieve symptoms and create a better environment for healing therapies such as platelet-rich plasma or stem cell injections. Proper use of ultrasound ensures accurate diagnosis and guides treatment procedures, minimizing risk and optimizing outcomes.
Inaccurate or incomplete diagnosis can lead to suboptimal results, unnecessary procedures, and continued pain. Thorough evaluation and targeted treatment are essential for successful recovery.
Caller Case: Trigger Finger and Hand Masses
A caller named Tila described experiencing trigger finger in all fingers, worsened by repeated injections. She also noted marble-sized masses at the base of her fingers. Possible causes include cysts (such as ganglion cysts), bone spurs (osteophytes), or inflammation of the tendons and pulley systems in the hand. The pulleys keep tendons close to the bone, enabling efficient movement. Inflammation can cause painful masses and trigger finger, where the finger locks in a flexed position.
Ultrasound and MRI are valuable diagnostic tools for identifying these masses. Treatment may involve injection therapies, using precise image guidance to ensure safety due to the dense anatomy of the hands and feet.
Joint Replacement Trends and Risks
There is a growing trend toward unnecessary joint replacement surgeries, especially in younger patients. These invasive procedures carry risks such as anesthesia complications, infection, hardware failure, blood clots, and strokes. Recent data shows a significant increase in joint replacements among patients under 65, with millions of knees and hips replaced annually. Despite declining reimbursement rates for hospitals, the number of surgeries continues to rise, raising concerns about the medical system’s focus on invasive solutions.
Joint replacement surgeries are elective, not mandatory. Conservative care is strongly encouraged, reserving surgery for cases where it is truly necessary. Regenerative medicine offers safer alternatives that preserve natural tissue and avoid the risks associated with surgery.
Regenerative Medicine as an Alternative
Regenerative therapies, such as platelet-rich plasma, stem cells, exosomes, and growth factors, harness the body’s natural healing mechanisms. By concentrating and injecting these cells under image guidance, joint health can be supported and pain reduced. Side effects are minimal—typically limited to temporary stiffness or soreness—compared to the risks of joint replacement surgery. The goal is to keep patients active, avoid pain medications, and prevent unnecessary surgeries.
Regenerative medicine is supported by ongoing research demonstrating its safety and effectiveness. It is a powerful option for treating joint pain, especially for younger patients or those with mild to moderate symptoms.
Common Causes of Joint Pain
There are many causes of joint pain, including:
- Osteochondritis dissecans (OCD): Common in young people, involving bone and cartilage damage, often due to trauma or poor blood supply.
- Juvenile rheumatoid arthritis (JRA): Chronic autoimmune condition causing joint inflammation, pain, and stiffness in young patients.
- Osteoarthritis: The most common form, resulting from wear and tear.
- Traumatic arthritis: Caused by significant injury or trauma.
- Autoimmune arthritis: Includes rheumatoid arthritis, psoriatic arthritis, and lupus arthritis, where the body’s immune system attacks the joints.
- Gout: Caused by uric acid crystal buildup, leading to intense pain and swelling.
- Septic arthritis: Joint infection from bacteria or viruses (e.g., staph, gonorrhea, Lyme disease).
All these conditions involve joint inflammation, which can cause pain and structural damage. Medications may provide temporary relief but do not cure underlying issues.
