Cartilage induction

Cartilage induction in knee and ankle joints avoids a prosthesis involving complex surgery in osteoarthritis. During this treatment, you do not get any foreign material into the body, but 100% of your natural and fully resilient cartilage.

How does cartilage damage occur?

What are the benefits of cartilage induction?

The advantage over previous cartilage regenerative measures is that the original cartilage is produced here. With this treatment, you have no foreign material in your body, but 100% of your natural and fully resilient cartilage. When inducing cartilage with chondrofiller, you only need a single minimally invasive procedure (arthroscopy). This is enough to reach and treat all cartilage defects.

Where can the chondrofiller be used?

Dr. Olaf Beck primarily treats knee and ankle joints with chondrofiller. In combination with a bone filler, bone cysts can also be filled and sealed with the chondrofiller.

What is chondrofiller?

Chondrofiller is a high-purity biological collagen implant that is ideal for treating cartilage damage. It consists of type 1 collagen and contains no cells. Collagen is found in all structures of the human body. It is the main component of skin, tendons and cartilage.

How does cartilage induction work?

In a joint scopy (arthroscopy), the cartilage is cleaned and then a 2-component gel is applied. The advantage of the chondrofiller is that the implant does not have to be cut to size, but completely adapts to the defect. After the operation, the joint should be spared for 2 weeks. The healing process results in an ingrowth of cartilage cells (cartilage induction). Complete regeneration of the cartilage can be seen just 6 to 8 months after the procedure. Another advantage of the method is that no cartilage cells have to be removed and inserted in a second complex operation with joint opening. It is currently the gentlest method for cartilage regeneration.

“Good and friendly practice organization, precise risk and medical opportunity advice with plenty of time for inquiries, high professionalism on the part of Dr. Beck. My decision to try chondrofiller treatment was the right one. I am pain-free after three months and run 'smoothly. ' And I am therefore really satisfied. ” — certified Jameda assessment

What are the limits of the process?

The limits of the chondrofiller lie in the defect size, which, however, must be determined individually (MRI images). Opposite defects can also be treated, but there are limits when there are defects in both the inner and outer joint gaps. For all joints, there must be no bone hardening (sclerosis) and bone cysts.

How much does a Chondrofiller treatment cost?

Reimbursement differs depending on the health insurance company. We recommend that you get a confirmation from your health insurance company before starting treatment.


How is a meniscus tear treated?

First of all, it depends on the degree of cross-linking of the meniscus tear. The damaged areas of the torn meniscus can be removed or sutured after diagnosis. During removal, the parts of the meniscus frayed by the crack are sheared off. This allows the rough surface of the torn meniscus to be smoothed out. In a few rare cases, the meniscus tear is restored by a transplant, which is sutured and replaced with donor meniscus or biological tissue replacement.

Can a meniscus tear heal by itself?

Whether the meniscus tear can heal by itself is also decided here on the basis of the degree of injury. You should also know that the meniscus contains various zones. Some areas have good blood flow and other regions that are more centered in the knee joint do not.

If the tear is in the well-circulated region of the meniscus and it does not go too deep into the poorly circulated areas, it can heal conservatively.

How long does it take for a meniscus tear to heal?

How long it takes for the meniscus to heal depends on the type and method of treatment and depends on the individual case of one of the patients. The exact type of injury and the location of the crack are decisive. It takes 6 to 14 weeks for the meniscus to heal in most cases.

How quickly does a meniscus tear have to be operated on?

The pain and inability to move can be painful after a meniscus tear. As a rule, the knee can no longer be fully extended or bent. You should therefore see a doctor as soon as possible to discuss the next steps.

What happens if a torn meniscus is not treated?

If you opt out of the recommended meniscus tear treatment, this will necessarily result in cartilage damage and osteoarthritis. The crack is further damaged with every movement until walking is only possible with great difficulty.


1. Risks?

Post-operative effect. If this occurs, the inner lining of the prosthesis and joint must be removed. Knee is then rinsed several times and then a “spacer” is inserted (bone cement prosthesis containing an antibiotic). This spacer stays in the body for an average of 6 months; the patient is not allowed to buy for 6 months. After 6 months, it is replaced by a full prosthesis.

2. Complications?

- Improper placement of the prosthesis:
- implants that are too big or too small

Movement restrictions, in the worst case worse after surgery than before.

3. Rehabilitation?

6-7 days KH. There are also rehab facilities or outpatient rehab (4 hours a day in a hospital and treatment there) → but is out of the question for people living alone.

4. Lifespan and durability?

Depends on various factors:

  1. quality
  2. medicines
  3. Gender and burden
  4. Positioning the load, loose prostheses must be replaced. It is advisable to check every 2 years so that any easing can be seen and prevented.

5th sport?

Biking, swimming, no problem. Stop-and-go sports, both shear forces acting on the knee joint, should be prevented as far as possible.

6. Is the right time for the prosthesis?

This is achieved when the patient says it can't get any worse. After the knee prosthesis has been inserted, the symptoms may be worse than before. If a patient can walk 5 km before surgery, he may only be able to run 500 m after surgery. Therefore, the right time is only when there is no other way out.

7. Duration of sick leave?

They work sedentary work earlier than stressful work. On average, it is 8-12 weeks.

8. How long do you walk with crutches?

After arthroscopy using degenerative procedures, supports must be run for an average of 4 weeks, then, depending on the findings, a splint takes over this function. However, if the meniscus is still implanted or if the upper and lower legs have cartilage damage opposite each other and has been repaired, this period is extended by 6-6 weeks, but depending on the patient's body weight.

9. What should you discuss with a doctor before knee surgery?

As a patient, you should leave the consultation with the feeling that you know that and why surgery may be necessary. This is the only way you can start the operation with a good feeling. Therefore, you should definitely ask what the alternatives to surgery are (and why they might not be an option for you). You should also ask what the possible risks of surgery are — more about this below — and when is the best time for surgery. If you are still unsure after the surgery consultation, get a second opinion.

10. Should I get a second opinion before knee surgery?

Knee surgery should be avoided if it can be avoided. On the one hand, every patient probably prefers to avoid going to the clinic; on the other hand, every operation represents a limited but existing risk that should only be taken when other forms of therapy have been exhausted. This is especially true when it comes to the question of whether an artificial knee joint needs to be inserted.

The knee joint is the joint in the body that is exposed to the greatest load. As a result, problems with the knee joint occur frequently. There are many things you can do to relieve the joint. Avoid knee-straining sports, but knee-saving physical activities and targeted exercises for the knee (physiotherapy); medications, bandages, orthotics — all of this can help reduce pain and relieve and stabilize the knees.

Even when surgery is unavoidable, the use of an artificial knee joint is often not necessary. There are already procedures that can even eliminate extensive cartilage damage with a transplant (cartilage cell transplant).

If an operation is recommended by your attending physician, then it makes sense to obtain a second opinion. Obtaining a second opinion is often also covered by health insurance companies. Of course, there are clear criteria as to when which procedure is to be used. But there are also borderline cases in which different specialists may well have different opinions. So if you want to be sure whether surgery is really necessary in your case, you should definitely get a second opinion from an expert in the field.

But always remember: The risk also represents an opportunity; avoiding one risk can lead to the next. If you refrain from knee joint surgery, this can not only lead to permanent pain and a restriction of mobility in the knee joint and thus quality of life. It can also have repercussions on the leg and hip should the pain cause incorrect strain in the knee.

11. How is the recovery process going?

This question is very individual and cannot be answered in general terms. It depends on the individual case and in particular on the type of surgical procedure. In any case, it will take several weeks before you can walk again without crutches after knee surgery, until you can fully exercise your knee again, usually up to six months, in some cases even 12 months.

In the case of a cartilage cell transplant, for example, the knee is usually able to regain normal strength only one year after the operation. The recovery process for cruciate ligament ruptures also takes a very long time; a full load may take place after six months at the earliest. This is more difficult to assess during meniscus surgery. The healing process can take from one week to six weeks. Whatever knee surgery you have, it is very important that physiotherapy starts immediately after the operation and that the recovery process is well supervised by professionals. Therefore, do not miss the follow-up tests. They contribute to the fact that

Whatever knee surgery you have, it is very important that physiotherapy starts immediately after the operation and that the recovery process is well supervised by professionals. Therefore, do not miss the follow-up tests. They help make the operation worthwhile for you and hopefully you can move (almost) pain-free again.

“Dr. Beck placed a meniscus implant on my knee and reconstructed the cartilage using a chondrofiller. Preliminary meetings, surgery and aftercare were first-class — including the results of the operation. Overall, the doctor and team have my full confidence. ”

What my patients say

“I found Arthoprax by chance during a Google search. Despite landing from abroad and the complicated diagnosis (cartilage damage to the kneecap), we were immediately impressed by Dr. Beck's expertise and rigour. Dr. Beck learned the complex process and carried it out in an exemplary manner. Dr. Beck is more thorough than any other orthopedist. During the first appointment, he spent almost 45 minutes with us to discuss the MRI results and X-rays. What immediately struck us was his holistic vision: the cause was perhaps not the sporting load (marathon running), but a misalignment of the hip or even a genetic defect. The day after the first meeting, I asked for an appointment for surgery and got it within two weeks (Beethoven Clinic in Cologne). Right after the operation, at 6:30 in the morning, Dr. Beck stopped by the clinic. The next day, he showed us photos on DVD showing the various cartilage wear points. In addition, he mentioned that the operation took two hours because he had to find solutions for other defects. For athletes, this practice is highly, highly recommended. Now I have hope once again of being able to save my knee joint and resume long-distance running. The experience with Dr. Beck and his team was simply great.”

“Dr Beck is a very good orthopedist, always nice and friendly. He also makes time for his patients. I had very severe knee pain and also had a knee arthroscopy in 2011 without much success, but another doctor did. After examination and MRI and consultation, Dr Beck explained the new collagen treatment in great detail and answered every question with great patience. When I decided to do this, Dr. Beck's surgery followed. I could hardly believe it, there is almost no pain, even physical therapy without problems. I can only recommend Dr Beck. But his practice team is also always helpful and very friendly. Thanks again for the loving care”

Verified Jameda Review

After a detailed survey about the symptoms in the knee, the examination followed and an initial diagnosis, which was confirmed by an MRI. This was followed by good and detailed advice, during which medical alternatives were discussed. After a period of reflection and further questions, which were answered patiently and in understandable terms, I opted for the “collagen gel” method to treat the cartilage defect as part of an arthroscopy. The operation, performed by Dr. Beck himself, went smoothly. There was no pain in the knee after the operation. The aftertreatment with appropriate therapies (lymphatic drainage, gymnastics) is very successful. I am completely satisfied! Thanks Dr. Beck and his team!”
