(Artificial Knee Model - Patent pending)



ARTHROKNEE, an artificial wet knee simulator model was developed by Dr Shammas B M and Dr Vaishnav R S in 2020, the patent application for which is pending.

The present invention provides a human anatomical knee model for arthroscopic procedures with critical anatomical structures important for a surgeon to identify and reference when performing knee arthroscopy and has the following components


  1. Artificial Femur and tibia bone ends to form the knee joint

  2. Medial and Lateral Menisci

  3. Anterior and Posterior Cruciate Ligaments

  4. Knee joint Capsule

  5. Medial and Lateral Collateral Ligaments

  6. Patella and its tendons

  7. Simulated Semitendinosus and Gracilis tendons

  8. Artificial Skin cover

  9. Clamp to attach to a surface


Simulators in the field of the medicine are becoming more popular  today.

The simulation system object of the present invention provides a considerable number of advantages, since on one hand it physically reproduces the the surface anatomy of the knee joint by means of a 1:1 scale plastic structure of real anatomical models and provides normal and pathological anatomical images similar to those provided by real models, while on the other hand, provides universality in that any arthroscope of any model can be used to visualize the interior and peform procedures.

The specifically developed simulation system gives a sense of reality rather than virtual, combining the use of the surgical instrument acting inside the anatomical model, generating real time images on the screen, providing a feel for handling the instrument, simulating surgical arthroscopy.


In addition to viewing the interior of the joint (Diagnostic Arthroscopy), numerous other exercises can be done using the model, namely Meniscal Balancing, Meniscal repair and ACL or PCL reconstruction


All steps of doing arthroscopy can done using this model, including skin incision, creation of portals, introducing the arthroscope, seeing all areas inside the joint, probing the structures to get a real feel of doing the surgery, finding the pathology, harvesting the graft for ACL/PCL reconstruction, preparation of the graft, measurement of the graft size, deciding the tunnel size to be drilled to fix the graft, preparation of femoral and tibial tunnels, passing the graft through the tunnels prepared and anchoring the graft onto the bone.
