Osteonecrosis of the knee after laser or radiofrequency-assisted arthroscopy: treatment with minimally invasive knee arthroplasty.

Background: Osteonecrosis of the knee after various arthroscopic procedures associated with the use of laser or radiofrequency devices has been described in a few case reports. The purpose of this study was to report on a series of nineteen patients with osteonecrosis of the knee after arthroscopic procedures. A literature search was done to compare this series of patients to previously reported cases.

Minimally invasive revision total knee arthroplasty.

Unlabelled: Exposure in revision total knee arthroplasty can be difficult. For example, eversion of the patella may require a number of procedures including vastus snips, V-Y turndowns, and tibial tubercle osteotomies. A minimally invasive approach further adds to exposure difficulties.

Minimally invasive total knee arthroplasty.

Currently, minimally invasive total knee arthroplasty is defined as an incision length of < 14 cm. However, the length of the incision is not the primary influence on potential postoperative benefits to the patient and should not be the only characteristic of the minimally invasive approach for knee arthroplasty. Some other factors that should also be included in this definition are: 1.
