Total knee arthroplasty (TKA) is a technique that offers excellent results in patients with degenerative OA of the knee ( 4 , 5 , 6 ). However, there is very little

Is outpatient TKA safe?
Outpatient TKA has been shown to be safe, has a low rate of hospital readmission and is economically advantageous. In fact, clinical results
present with pain and audible sound when extending the knee from 30° to 45° of flexion. As the knee is moved from flexion to full extension, it is believed that this nodule jumps abruptly from the intercondylar notch in PS knee designs, resulting in the

Indications for UKA
The best indication for UKA is painful OA in an isolated tibiofemoral compartment (medial or lateral). Lateral

In contrast with the past where a varus thrust and instability were contra-indications to HTO owing to reported inferior results,
