Anterior Cruciate Ligament Rupture
The anterior cruciate ligament is commonly injured, patients usually describing a twisting mechanism with painful instability, or a painful back kneeing or hyperextension of the knee. The injury may be associated with a sensation of popping of crunching and is usually associated with the rapid subsequent development of swelling and stiffness.
The diagnosis should be suspected in these circumstances and patients presenting to hospitals in this way are usually x-rayed before being referred for assessment by a senior physiotherapist or knee surgeon, following which further medical imaging may be arranged.
The treatment of anterior cruciate ligament injuries has advanced considerably during the last decade and should surgical treatment be required it is now performed arthroscopically using techniques that facilitate accelerated rehabilitation. Any injuries to the shock absorbing cartilages or running surfaces of the knee can then be addressed simultaneously.
