    Anterior Cruciate Ligament Rupture: Who should have surgery?

    Anterior cruciate ligament (ACL) rupture is a common injury among athletes. It usually occurs after a rotational injury whilst pivoting off the affected leg. The injury usually causes acute pain and swelling which often settles within a few weeks.

  • Travel after joint replacement

    Generally, it is safe to travel long distances by plane from 6 weeks post joint replacement. This seems to be the higher risk period for complications such as Deep Vein thrombosis (DVT) and Pulmonary Embolus (PE). After 6 weeks, the risk has returned to normal background levels. Of course, all patients present different individual risk profiles, and the specific issue of travel after joint replacement should be discussed with your surgeon.

  • Computer Navigated Total Knee Arthroplasty

    Computer navigated total knee arthroplasty is a proven and useful technique to help plan, execute and document knee replacement procedures. During the operation, the surgeon digitises preoperative information about alignment and instability and then plans the appropriate surgery in real time on the computer. The surgeon then places cutting jigs on the bone according to the accurate planning that has just taken place.
