Prosthetic reconstruction of the anterior cruciate ligament of the knee: the roles of CT scan and M.R.
The authors examined 10 patients treated by intra-articular reconstruction of the anterior cruciate ligament with an artificial ligament in terylene (Kejo-Leeds type). Clinical evaluation was supplemented by CT scan and magnetic nuclear resonance (M.R.). The basic parameters assessed were the positioning of the tunnels, biological anchoring, presence of reactive synovitis, growth and modification of periligamentous fibrous tissue, characteristics and relationships of the extra-articular plastic. CT scan was better at determining the tunnels, evaluating biological anchoring and visualising the new ligament in its intra-articular course. Magnetic nuclear resonance was better at evaluating changes in the periligamentous tissue. The authors therefore conclude that M.R. is preferable in the early follow-ups, while CT scanning has greater diagnostic value in follow-ups after six months.
