In Achilles tendinopathy, the neovascularization, detected by contrast-enhanced ultrasound (CEUS), is abundant but not related to symptoms.

Purpose And Hypothesis: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory.

Non-reducible knee dislocation with interposition of the vastus medialis muscle.

Irreducibility of the knee following complete dislocation is a rare event determined by the interposition of various capsulo-ligamentous structures in the joint space. Such cases often require urgent surgical treatment. We report the case of a healthy 70-year-old man with a sprain of the left knee that occurred after a sports trauma.

Rotating knee prosthesis. Surface or hinge replacement?

Until the early 1990's our experience in Total Knee Replacement (TKR) was based on AGC 2000, Tricon M and MG implants. Starting from 1992 we decided to use a rotating knee prosthesis. At that time in Italy there were many knee replacement devices with rotating elements: Oxford, LCS, Rotaglide and Endomodel from Link.
