What it is
Osteoarthritis, also called arthrosis, is a chronic condition in which the cartilage lining a joint gradually thins and wears away. Cartilage works as a shock absorber; as it breaks down, the bones start to rub against each other, causing pain, stiffness and a smaller range of movement. It is a degenerative rather than an inflammatory disease, although flare-ups with swelling do happen.
The joints under the heaviest load are affected most often: the knee (gonarthrosis), the hip (coxarthrosis), the ankle and the small joints of the hand. Treatment gives the best results at early and moderate stages, while the joint surfaces are still in fair condition; if the stage is advanced, the doctor will say plainly when joint replacement is the more realistic choice.

1An examination of the joint and a review of your X-rays, MRI or ultrasound let the doctor decide if the procedure is suitable. Existing scans can be sent in advance of the visit.
2A little blood is drawn from a vein; platelet-rich plasma with growth factors is prepared from it later.
3About 30 ml of adipose tissue is taken through a puncture in the abdomen or inner thigh, with local anaesthetic. The puncture needs no stitches.
4The centrifuge spins the sample until it separates into layers; the isolated stromal vascular fraction is then mixed with the platelet-rich plasma.
5Under ultrasound guidance the prepared material is injected straight into the affected joint, which helps to place it precisely.
6You go without crutches and without a hospital stay; the doctor keeps in touch afterwards and follows the joint's response.

Results

The joint may ache a little more — this is an expected reaction.

The pain usually eases.

Mobility and activity improve.

The full effect develops.
How long it lasts differs from person to person and depends on the stage of the condition, body weight, activity and other factors — no one can promise a fixed result.
Comparison
Your own blood and adipose tissue only; donor and synthetic material are not used
A little of your adipose tissue is taken and processed so that the stromal vascular fraction (SVF) can be separated: cells that help tissues repair. This is combined with your own plasma and injected into the joint affected by the disease.

Its main use is at early and moderate stages of osteoarthritis, to slow the wear of cartilage and lessen friction between the joint surfaces.
Platelet- and growth-factor-rich plasma is separated from a small amount of your blood and then injected into the joint, helping to calm inflammation and create better conditions for tissue repair.

For mild osteoarthritis it is often used alone, and with SVF when the effect needs to be stronger.
The benefits and timings shown are averaged and given for guidance: the plan and recovery depend on your joint and individual features, and the doctor confirms them at the consultation.

Doctors usually describe four stages, from early thinning of the cartilage to severe wear. Injection treatment is most often considered in the early and middle stages; the doctor decides after reviewing your X-ray or MRI.
The cartilage over the bone ends of a joint gradually wears out. As it becomes thinner, cushioning is lost and the bones rub against each other, bringing pain, stiffness and crunching. This is a degenerative disease, not an inflammatory one.
Frequently yes, if treatment is not delayed. With SVF and PRP injections the aim is pain relief and cartilage support without an operation. Joint replacement remains the last option, used when the joint is already destroyed.
Many patients report the first changes 2–3 weeks after the procedure. A stable result develops over about six months and lasts from several months to several years depending on the individual. Because osteoarthritis is chronic, the approach is an ongoing plan rather than a single injection.
At early and moderate stages. The milder the stage, the quicker and more lasting the effect tends to be, and it may reduce how often hyaluronic acid injections are needed. At the most advanced stage, when the joint space has nearly gone, a lasting effect should not be expected.
The joints with the highest load, namely knees, hips and ankles, as well as the small joints of the hand and the spine. Regenerative treatment covers all of these joints.
It usually progresses: pain becomes constant, movement becomes more limited, the joint may become deformed and walking can become difficult. Early diagnosis, weight control, exercise and working with a doctor make a real difference.
The main tool is an X-ray, showing the stage. For detail on cartilage and soft tissues there is MRI; ultrasound reveals inflammation and fluid in the joint; blood tests help rule out inflammatory conditions. The doctor can look at results you already have free of charge.
Osteoarthritis — cartilage wear, aching pain during movement, crunching and stiffness after rest. Arthritis — inflammation, pain at rest and at night, swelling, redness and warmth over the joint. The approaches to treatment differ, so the first step is the diagnosis.
Of course. A doctor reviews your X-rays, MRI or test results free of charge, assesses the stage of osteoarthritis and suggests a non-surgical plan when it is appropriate — just send them.
Yes, and it helps. Well-chosen activity strengthens the muscles that unload the joint, improves the cartilage's nutrition and keeps you mobile. Swimming, water aerobics, cycling, Nordic walking and yoga work well, while running on hard surfaces, jumping, heavy lifting and sudden movements are best avoided.
About the conditions
Arthritis is an inflammatory disease of the joints. Typical signs are pain at rest and at night, morning stiffness lasting more than 30 minutes, swelling, redness and warmth over the joint. Causes include autoimmune conditions such as rheumatoid arthritis, infections, gout and psoriasis.
At early stages, PRP or SVF injections combined with exercise therapy and physiotherapy can reduce pain and improve movement. If the joint is already badly damaged, replacement may be the more realistic option — the doctor will tell you honestly after seeing your scans.
At early stages (1–2), SVF therapy may be considered to support blood supply to the femoral head and delay the need for joint replacement. At later stages surgery is usually required.
Osteoarthritis, also called arthrosis, is a chronic condition in which the cartilage of a joint gradually thins and wears away. For patients from Utrecht, it usually shows as aching pain on movement, stiffness after rest and crunching in the joint.
The procedure does not require crutches or a hospital stay. Patients from Utrecht return to normal daily activity within a day or two and receive recommendations on load for the first weeks.
Knee or hip osteoarthritis? Patients from Utrecht can send their X-rays or MRI and get a free assessment of the stage and a clear answer on suitable treatment and its price.
Utrecht had 378,140 inhabitants on 1 January 2026, and the municipality expects about 400,000 by 2030, 450,000 by 2039 and 488,000 by 2045. A larger and ageing population in any city means more people noticing that stairs, long walks or a morning start have become uncomfortable. Osteoarthritis (arthrosis) is a slow, chronic wearing of the cartilage that lines the joint. Healthy cartilage softens impact; when it thins, the bones rub on each other and the joint hurts, stiffens and moves less.
Knees (gonarthrosis) and hips (coxarthrosis) are affected most, because they carry the greatest load. The ankle and the small joints of the hand follow. It is a degenerative condition rather than an inflammatory one, although flare-ups with swelling do happen. That difference matters, because arthritis, with pain at rest and at night, morning stiffness and a hot, red joint, is treated with a different approach, and diagnosis comes first.
The city is also young in places. About 67,000 students study in Utrecht, and Hogeschool Utrecht alone has around 37,000. Young adults rarely think about cartilage, but old sports injuries, sprains and meniscus damage can lay the ground for wear years later. The same joint conditions, from early thinning to late wear, appear across all ages, so the first question is always the stage of the joint rather than the age on the passport.
According to the figures available, 51% of journeys within Utrecht are made by bicycle, more than by any other mode, and the bicycle parking station by Central Station holds 12,500 bicycles. Cycling is a gentle, low-impact way to keep knees and hips moving, and the service text lists cycling among the sensible activities for people with osteoarthritis, alongside swimming, water aerobics, Nordic walking and yoga. Muscles that unload the joint and better nourishment of the cartilage are the reasons exercise is advised, not rest.
Sport adds another kind of load. SV Kampong has 4,500 members and is described as the largest amateur sports club in the Netherlands. For members who play pivoting, jumping or running sports, the doctor will usually ask about old injuries, because the text names running on hard surfaces, jumping, heavy lifting and sudden movements as things to avoid once a joint is already painful. Physical work with repeated heavy lifting falls in the same category.
Recovery after injuries and operations is one of the situations in which the treatment is considered. The doctor looks at your X-ray, MRI or ultrasound and decides whether the joint suits an injection approach. Pain, crunching or stiffness, painkillers that help only briefly, and a wish to avoid or postpone joint replacement are the typical reasons people ask for a review.
At the De Bilt station, January has a mean maximum of 6.1 °C and a mean minimum of 0.9 °C; February reaches 7.0 °C and 0.7 °C, and December 6.7 °C and 1.6 °C. Relative humidity is 82% over the year and 89% in November and December. There are about 25 snow days a year, six each in January and February and five in December. Sunshine falls to 55.5 hours in December and 66.6 hours in January, against 213.9 hours in July.
Many people with osteoarthritis report that stiffness after rest feels worse in damp, short winter days. The service text describes stiffness after rest as a typical sign of cartilage wear, in contrast to the pain at rest and at night that points to inflammation. We do not claim that the weather causes the condition; it is simply a season in which the joint is noticed more, and when everyone tends to move less. A joint that is moved less gets less nourishment, so a winter routine of gentle cycling, swimming or yoga is worth planning.
Mid-November brings the four-day Le Guess Who? festival across venues in the city, and the Netherlands Film Festival fills September and October. Long evenings standing or sitting in a cinema seat can be a small test for an aching knee or hip. If you notice that a joint locks up after sitting, that is a useful detail to describe to the doctor at the consultation, together with how long the stiffness lasts in the morning.
Body weight is one of the factors named in the service text that influence how long the effect of treatment lasts, together with the stage of the condition and activity level. National statistics show why this is relevant. According to CBS, 50.4% of Dutch adults aged 18 and over were overweight in 2024 (BMI of 25 or more), and 15.7% of them were obese (BMI of 30 or more). In 2014 the figures were 49.4% and 13.3%. CBS also reports that in 2023, 16% of adults aged 20 and over were obese, three times the 5% of the early 1980s.
Knees and hips carry the weight of the whole body with every step, so a lower weight eases the load. The text speaks of early diagnosis, weight control, exercise and working closely with a doctor as the things that make a real difference. In the Netherlands, bariatric surgery for adults is included in the basic package only under strict conditions, and a lifestyle programme (GLI) is typically tried first. That shows how seriously weight is treated as a health matter, but it is a separate topic from joint treatment.
Our doctors do not ask anyone to reach a certain weight before a consultation. What the doctor reviews is the joint itself: the X-ray for the stage, the MRI for cartilage and soft tissue, the ultrasound for fluid and inflammation, and blood tests where needed to rule out inflammatory disease. Weight, activity and other factors then help to set realistic expectations about how long the effect may last.
Dutch basic insurance works on the principle of a medical reason. The national institute Zorginstituut Nederland states, for plastic surgery, that care is covered only where there is a medical indication, and that some insurers require prior approval (machtiging). The mandatory annual deductible (eigen risico) applies to covered care, while GP care is exempt. Those pages concern other procedures and say nothing about injection therapy for joints, so we do not state what your insurer will or will not reimburse for this treatment. The practical step is to ask your own insurer directly before you decide.
The consultation and the review of your scans are free of charge and carry no obligation. Send your X-rays, MRI or ultrasound to the coordinator on WhatsApp or Telegram, where answers come round the clock, and a doctor will assess them independently. The doctor quotes the cost for a plan only after the review, because it depends on the joint, the method and the stage of osteoarthritis.
Public holidays in the Netherlands, such as King's Day on 27 April and Liberation Day on 5 May, can slow down the opening of your usual healthcare providers when you want to collect scan reports. Messaging the coordinator is not affected by them, so you can send the images you already have at any time and have them reviewed before you decide on anything else.
The treatment uses your own blood and your own adipose tissue; nothing donor or synthetic is used. A small blood sample is taken from a vein to prepare platelet-rich plasma (PRP). Under local anaesthetic the doctor collects roughly 30 ml of adipose tissue through a puncture on the abdomen or the inner thigh, and stitches are not needed. The sample is spun in a centrifuge, the stromal vascular fraction (SVF) is isolated and blended with the plasma, and the material is injected into the affected joint under ultrasound guidance. The whole procedure is done in one day.
Afterwards there are no crutches and no hospital stay. In the first week the joint may ache a little more, which is an expected reaction. After about a month the pain usually eases, mobility and activity improve at around three months, and the full effect develops at about six months. Some patients notice early changes after 2–3 weeks. How long it lasts differs from person to person, and no one can promise a fixed result.
Osteoarthritis is chronic, so it needs an ongoing plan rather than a one-off injection. The doctor keeps in touch after the procedure and follows how the joint responds. The approach suits early and moderate stages best. In advanced cases, where the joint space has almost disappeared, a lasting effect cannot be expected, and the doctor will say frankly if a joint replacement is the more realistic option.
The weather does not cause osteoarthritis, which is wear of the cartilage. Many people simply notice stiffness after rest more in cold, damp months. De Bilt has January highs of 6.1 °C and humidity of 89% in November and December. Keeping moving with swimming, cycling or yoga is the usual advice, and the doctor can judge your joint from your scans.
Cycling is among the activities listed as suitable for people with osteoarthritis, because it builds the muscles that unload the joint and feeds the cartilage. Running on hard surfaces, jumping and heavy lifting are the things to avoid. If cycling itself causes sharp pain, describe it to the doctor during the consultation.
We cannot say. The national guidance we looked at concerns other procedures, such as plastic and bariatric surgery, where a medical reason and sometimes prior approval (machtiging) are required. Ask your insurer directly, and remember the mandatory deductible (eigen risico) applies to covered care, while GP care is exempt.
Yes. X-rays, MRI or ultrasound reports can be sent to the coordinator on WhatsApp or Telegram, and a doctor reviews them free of charge. The review establishes the stage of osteoarthritis and whether a non-surgical plan seems appropriate. If you do not have scans yet, the coordinator will explain which ones are most useful.
Body weight is one of the factors that influence how long the effect lasts, together with the stage, activity and other individual features. It does not decide eligibility alone. The doctor reviews the joint and explains what to expect. Weight control and exercise are part of the long-term plan for a chronic condition.
Not necessarily. Suitable activity helps the joint, while running on hard surfaces, jumping, heavy lifting and sudden movements are best avoided once the joint hurts. After the consultation the doctor can tell you how to adjust your training to the stage seen on your scans.
The procedure takes one day, with no crutches and no hospital stay, so the season matters little. Plan around temporary reasons to postpone: a raised temperature, a cold or flu, or inflamed skin above the joint. A winter cold would therefore mean waiting until you are well.
It is not suitable for cancer, pregnancy, blood clotting disorders, acute infections, including infection in or near the joint, or a flare-up of a serious chronic illness. A doctor decides after examining you and reviewing your scans.
