Wide range of uses in all areas of arthroscopy.

The instruments of the Arthro.LINE have completely proven themselves in all fields of arthroscopy. We explain in the following how exactly such use takes place in practice based on an operation which is frequently carried out, namely knee arthroscopy.

Anatomy of the knee joint
The knee is the largest and at the same time most complicated joint in the human body. As it supports almost the entire weight of the body, it must withstand great loads. As a so-called genuine joint, it has a joint gap. In the knee joint – which is surrounded by a joint capsule - the thigh bone (femur), the shinbone (tibia) and the knee cap (patella) meet.



Outer collateral ligament


Outer meniscus


Posterior horn


Anterior horn


Shinbone plateau (tibial plateau)




Thighbone (femur)


Knee cap (patella)


Cartilage surface of the thigh condyle


Front cruciate ligament


Rear cruciate ligament


Inner collateral ligament


Inner meniscus




The joint ends of the thigh meet with the plateau of the shinbone (tibial plateau) with two differently curved condyles (rounded prominences). These different curvatures are compensated for by two cartilage disks – the inner and the outer meniscus. 

The knee is provided with support and guidance internally by the cruciate ligaments. From the outside, the inner and outer collateral ligaments have a stabilising effect. The patella also contributes to the functioning of the knee to a considerable extent. It is embedded in the pattelar ligament as a sesamoid bone and joined to the thigh muscles and the lower leg.

Frequent injuries of the knee joint

  • Meniscus injury (traumatic or degenerative)
  • Injury of the inner collateral ligaments and of the front cruciate ligament
  • Wear/arthrosis
  • Patella problems

With these injuries, a minimally invasive operation in the form of a knee arthroscopy is often necessary. Special instruments are required for this.

Procedure of a knee arthroscopy

  • Application of a general or local anaesthetic
  • To minimise blood loss during the operation, a cuff is applied above the knee as a tourniquet
  • Now the knee is opened up with two small cuts of 0.5 cm and the arthroscope is introduced
  • To widen the joint cavity, a sterile fluid (Ringer's solution, Purisole solution, NaCl solution) is injected into the knee
  • The next step is to examine the mucous membrane of the joint, individual joint sections, the cartilage areas, the meniscuses, the cruciate ligaments and the back of the patellas
  • The joint structures are examined with a probe (test hook)
  • Based on the diagnosis, depending on the type of operation, various Hand Instruments are used to perforate, cut and grip the damaged tissue
  • Shaver-Blades are ideal for cutting and milling bones, cartilage and sections of tissue. They are composed of a fast rotating blade (inner tube) and an integrated extraction device which enables very efficient work
  • The connected Shaver-System rotates the blade at speeds of between 800 and 8,000 rpm
  • After the operation, the instruments are removed and – after thoroughly rinsing the joint – the cuts on the knee are sewn up
