TKA was performed via a minimally invasive
approach which involves a shorter skin incision and
a mini-mid-vastus access to the joint and the use of
extramedullary guides. No tourniquets were applied. The
average operating time for TKA was 45 minutes. THA
was performed using either a modified posterolateral
approach passing through the gemellus inferior and the
quadratus femoris muscles or an anterolateral Rottinger
approach to minimise damage to muscle tissue, followed
by implantation of neck-preserving short stems. The
average operating time for THA was 40 minutes.
