Minimally invasive knee surgery at Beta Klinik is often performed arthroscopically. It is also commonly known as knee arthroscopy, knee endoscopy or keyhole surgery. Knee arthroscopy has revolutionized the treatment of knee injuries because it is gentle since less tissue is damaged, and it has a lower risk of infections in comparison to open surgery. In addition to that, it has shortened recovery periods and the duration of hospitalization, and it makes a quick return to work, sports and daily activities possible.

During knee arthroscopy, an endoscope is inserted through small incisions of about 1 cm length (0.4 inches). Inside the endoscope is a camera that enables us to visualize the inner of the knee as well as damaged structures enlarged at a monitor.

Due to these features, knee arthroscopy is also an effective diagnostic procedure since damaged structures can be directly visualized in opposite to imaging procedures like MRI, CT or X-raying. This makes a direct evaluation of the extent of the injury possible.

Another advantage of knee arthroscopy is that therapy may directly follow diagnostics during the same procedure because the physician can insert small instruments and operate with them. This way, damaged structures, for example, may be stitched, removed or stabilized.

General advantages of minimally invasive knee surgery and knee arthroscopy

(in comparison to other surgery methods, extent may vary subject to the surgery type)

  • minimally invasive
  • easy on the body
  • reduced risk of infections
  • short periods of hospitalization and recovery
  • quick return to work, sports and daily activities
  • diagnostics and treatment are possible within the same procedure (arthroscopy)

Return to work after minimally invasive knee surgery / knee arthroscopy

After a short hospitalization of a few days, the inability of work amounts 2-6 weeks. Sitting work postures are possible much earlier than physical labor postures. Physical, knee-intensive labor can be resumed after 12 weeks (tibial osteotomy).

Special fields of application of minimally invasive knee surgery / knee arthroscopy

If meniscal tissue is destroyed, a gentle smoothing of the ‘buffer’ is performed. Reconstructable tears are stitched or anchored with modern anchor systems.

In rare cases, a larger part of the meniscus has to be removed. After the removal, we can insert a synthetic meniscus during an additional surgery. The artificial tissue serves the body as anatomic landmark to generate a new scarred meniscus that does not have the quality of a natural meniscus but is an adequate alternative to a missing one.

Anterior cruciate ligament injury / ACL tear / cruciate ligament rupture

To enhance stability and avoid consequential damage resulting in knee arthritis, our surgeons perform minimally invasive, arthroscopic cruciate ligament replacement by using a tendon of the own body. The primary implant is the semitendinosus tendon (without gracilis tendon!), which is extracted performing a cosmetically appealing technique through an incision of about 2-3 cm (0.8-1.2 inches). After processing the tendon (triple/quadruple technique, img. 6), it is fixed (femoral placement/anteromedial). We use a special titanium fixation system at the thigh bone (TightRope®) and at the lower leg either bioresorbable screws (self-dissolving) or the same fixation system.

Luxating patella / patella dislocation / kneecap dislocation

In case of a luxating patella, often the inner stabilization system of the kneecap is destroyed, the so-called MPFL complex (medial patellofemoral ligament complex). This anatomic structure was discovered a couple of years ago, and it is the new center of attention of patella stabilization surgery. At Beta Klinik, we perform the modern, minimally invasive MPFL replacement.
