At Lumm Medical, we address osteoarthritis (shoulder, knee, hip) as a chronic inflammatory process and an imbalance in tissue repair.
We use Mesenchymal Stem Cells (WJ-MSCs) to modulate inflammation and guide cartilage repair, with objective monitoring (scales and imaging).
On-site laboratory and process control for WJ-MSC cultivation.
Objective monitoring (scales and imaging)
Comprehensive approach (5 Pillars: Psyche, Movement, Rest, Nutrition, Appearance)
May help postpone or avoid surgery, depending on the stage of the disease.
High-precision ultrasound guidance
Do you see yourself reflected in any of these situations?
Osteoarthritis, commonly known as “joint wear,” is often presented as an inevitable process, forcing many people to accept progressive restrictions in mobility, independence, and quality of life.
Enter a cycle of chronic pain and reduced mobility → sedentary lifestyle, frustration, and impact on daily life, passions, and work.
Chronic NSAIDs (non-steroidal anti-inflammatory drugs, prolonged use) with hepatic and renal risks.
“Wait for the prosthesis” as a final solution.
Invasive surgeries that do not always ensure good results and can leave the tissue vulnerable to new injuries / re-ruptures.
Viscosupplementation that does not generate structural changes in the cartilage, only hydrates.
Less mobility → the body no longer responds with the same strength or speed as before (frailty syndrome) and loss of strength and muscle mass (sarcopenia)
Increased risk of chronic non-communicable diseases (hypertension, obesity, diabetes) and neurodegenerative disorders (Alzheimer’s, Parkinson’s).
At Lumm Medical: “taking care of your knees is taking care of your brain.”
Osteoarthritis is not just “wear and tear”: it is chronic inflammation and imbalance in repair. We seek an alternative that addresses the root, repairs, and regenerates tissue to recover mobility, vitality, and quality of life.

We confirm the degree of damage, causes, and general condition.
We define if you are a candidate and rule out risks.
Realistic goals: repair/regenerate cartilage, reduce pain, improve mobility and function (daily/sports).
Mesenchymal stem cells from the umbilical cord that modulate inflammation and direct repair (cartilage, tendons, ligaments).
We measure progress and activate regenerative rehabilitation to enhance results.
Persistent pain due to osteoarthritis in the knee, hip, shoulder, or other joints (associated comorbidities).
Stiffness and loss of mobility that affect daily life or sports, with a desire to regain function and return to activities.
People looking to improve their quality of life with a lasting solution (cell therapy acts in the medium and long term, it is not an immediate relief).
Less pain and greater mobility.
Some people feel an initial phase of relief (“honeymoon”) associated with the reduction of substance P; then the improvement is progressive in the medium and long term.
Recover function in daily and/or sports activities.
It is supported with post-treatment physiotherapy to optimize biomechanics and enhance the effectiveness of the therapy.
Better quality of life with a comprehensive approach.
We work on physical, mental, emotional, sleep, and appearance health.

Times and sessions
They depend on your diagnosis and the indicated protocol.

Con el desgaste de mi rodilla, tenia programado y autorizado una osteotomia para cambiar el angulo de apoyo y estirarle la vida antes de protesis. Opte por celulas madres en Lumm y evite la cirugia y estoy practicando tenis diario. La fisioterapia con el tratamiento de Lumm me mantuvieron activo. maria elena arroyaveTrustindex verifica que la fuente original de la reseña sea Google. Una experiencia maravillosa en la atención, cuidan cada detalle para que te sientas cómodo y atendido. Melisa una profesional que te hace sentir tranquilo, con su dulzura y caridad en la información. Me sentí muy cómoda, tranquila y satisfecha con el procedimiento recibido. Totalmente Recomendable. Jorge SeguraTrustindex verifica que la fuente original de la reseña sea Google. Me acerqué a la clínica después de valorar diferentes tratamientos con células madre en Europa. Tras comparar varias opciones, encontré que en esta clínica no solo ofrecían un precio competitivo, sino también el conjunto más completo de pruebas y un seguimiento exhaustivo antes y después del tratamiento. Cuentan con un equipo muy bien conformado; cada profesional está informado y preparado para adaptar el tratamiento a las necesidades de cada paciente. Terminé hace pocos días mi tratamiento en las muñecas y la columna, y todo ha evolucionado según lo previsto. Ahora debo continuar con las recomendaciones y los ejercicios indicados, y me siento muy optimista con los resultados, que sé llegarán progresivamente Xerxes FrechianiTrustindex verifica que la fuente original de la reseña sea Google. Lumm is absolutely incredible! I made it a priority to fly to Colombia just to meet with them and I was beyond impressed. I’ve had shoulder issues and pain for many years so I was interested in real high quality stem cells. Their staff was extremely professional and assisted step by step in their top tier clinic. I received 40 million stem cells in my shoulder and it was the best decision I made. If you have discomfort or pain, do something about it! I’m glad I came to Lumm Medical for stem cells and I highly recommend them. They will treat you like family! Marcee RubyTrustindex verifica que la fuente original de la reseña sea Google. A beautiful clinic with kind, helpful staff. They provide a 360 degree look at your health and consult with experts on every aspect. We were very happy with the recommendations made. A bonus was Dr. Alejo’s discovery that my husband was on the wrong heart medication. We highly recommend their services. Hugo BonjeanTrustindex verifica que la fuente original de la reseña sea Google. I visited Lummedical on July 23rd this year. I had been been limping for a year due to a meniscus tear and some other related damage to my knee which had also lead to muscle loss. Dr. Alejandro was fantastic. First doctor who walked me through all the MRI images and showed me in detail everything that was damaged in my knee. He recommended a stem cell injection in my knee and some in my muscles which were inflamed. I did not think I was going to be able to afford it since I had reached out to some other clinics in Colombia and Mexico that had all given me pricing that was way out of my budget. But the Lumm proposal came in much lower and more reasonable. They have their own lab and that afternoon I got my stem cell injections. I was warned of the swelling it would cause. And the knee did swell by the following morning to such an extend that my muscles did not work anymore. They send a physio therapist to my room to reactivate the muscle. There were small improvements on Friday and Saturday. However, I got frustrated because my leg muscles were still not functioning and I had to travel back home on Tuesday. Dr. Alejandro listened to my concerns on Saturday late afternoon and offered to come to my apartment on Saturday evening. He worked with me for an hour to reactivate the muscle and by the end of that hour my leg muscles were working and I was walking again. Slow, but walking. Sunday morning they send a physiotherapist to my room again and I managed to walk better and walk up and down the street, but still limping. Monday morning another physio session at my apartment after which I managed to walk without a limp. On Tuesday we traveled back home without any issues. Since then my knee and leg have been getting stronger every day. I do my physio exercises daily and extend my walks and challenge my leg continuously. I walk longer distances now, up hill and down hill and the only time I still feel the knee/leg is not entirely back the way it was is when I go down the stairs, but also that is getting better every day. All this in just 5 weeks. Over the following month I plan a lot of hiking in the hills and am convinced that my knee and leg will be completely back to normal and regain their strength by the end of September. The staff and physiotherapist at Lumm and Dr. Alejandro are all great caring people. I have experienced health care in Belgium, Canada and the USA because I lived in all of those places. Lumm has offered me one of the best health care experiences in my life (I am 60). I felt that the entire team truly cared about me and my health. Can't recommend them enough and I know where I will go for any joint or other issues in the future. Lisa DouglasTrustindex verifica que la fuente original de la reseña sea Google. The doctors at Lumm Medical are amazing—such an ethical, dynamic team. They gave me so many viable stem cells, and I can honestly say I feel fantastic. My brain fog is gone, my energy is up, and I just feel younger and more vibrant overall. Even my inflammation markers have dropped. Such a wonderful group of people doing incredible work!La evaluación general en Google es 5.0 de 5, en base a 15 reseñas

What is osteoarthritis? Cartilage wear in joints (knees, hips, shoulders, etc.). Lumm Medical understands it as a chronic inflammatory process due to an imbalance in repair mechanisms (key immune system).
Chondromalacia vs osteoarthritis? Chondromalacia is loss of cartilage integrity; osteoarthritis is a more advanced stage with bone involvement.
Chronic pain in knees or other joints with a diagnosis of osteoarthritis/chondromalacia.
“Trac-trac” and joint noises may be a risk of wear.
You want to avoid or postpone surgery and are looking for a less invasive alternative.
Limitations of conventional treatments: partial relief, side effects, temporary solutions.
Integral 360: evaluation (blood/NAD, ergoespirometry, holter, nutrigenomics, body composition, psychological/psychiatric evaluation) + images (MRI/echo).
Personalized plan: diet, exercise, rest, emotional management, and physiotherapy.
Cell therapies (MSCs): migrate to the site, modulate inflammation, and orchestrate repair.
Homing: detect damage and migrate to the lesion.
Immunomodulate: reduce chronic inflammation.
Induce repair: coordinate cells such as macrophages to generate more resistant tissue.
Less invasive than surgery.
Surgery: resolves the mechanical, but does not always improve the intrinsic quality of the tissue; risk of re-injury.
Viscosupplementation: does not produce structural changes in the cartilage.
Chronic NSAIDs: relieve, but with renal/hepatic risks and without addressing the cause.
High-precision echo-guided infiltration with ultrasound guidance at the point of injury.
Immediate movement and regenerative rehabilitation: total rest is not ideal; movement activates the cells.
Lumm physiotherapists guide pain/mobility from the first moment.
Not immediate: improvements in the medium and long term (from 3 months to 1–2 years).
Objective measurement before/after: pain/function scales, images (MRI/radiographs), and blood parameters.
Evidence of improvements in severe degrees of chondromalacia; cases with cartilage reappearance have been observed after 3 years of follow-up.
Rigorous and ethical selection: pathology, commitment, and habits are evaluated. Not every patient applies.
Active cancer.
Decompensated chronic diseases (coronary, heart failure, uncontrolled pulmonary/renal, autoimmune in crisis).
Anticoagulation or coagulation disorders
Lack of evidence for specific pathologies.
active infection
Advanced stages of the disease
It is part of a journey of transformation: it requires healthy habits (diet, exercise, rest, emotional management).
Lumm accompanies with education and monitoring to maximize and sustain results.
