High energy trauma represents with 82 % the most frequent etiology of PCL injuries. 92 % of these occur in combination with other ligaments and are diagnosed as complex knee ligament injuries. Only 18 % are diagnosed as isolated PCL ruptures and are most commonly related to sports injuries. Chronic PCL instability leads to change of knee kinematics with increased anteromedial joint pressure force by negative Bandi effect as well as to increased patellofemoral pressure and secondary osteoarthritis.
The natural history of the posterior knee instability leads to:
- Increased posterior translation of the tibia
- Change of center of rotation
- Increased cartilage damage of the anteromedial tibia plateau
- Increased pressure on the patellofemoral joint and osteoarthritis
Posterior knee instability is still nowadays under diagnosed and therefore a detailed algorithm for clinical evaluation of knee instability is necessary.
Anterior Knee Instability is diagnosed by using Lachman- test and the amount of instability is graded +/ ++/ ++ (0 – 15 mm). The anterior drawer test is carried out as well and performed in internal – neutral and external rotation to detect additional peripheral instability.
PCL Instability is clinically diagnosed by using the...
