At last some evidence to back up what i have been saying......


"If you have an uncemented total hip, its fixation to the skeleton improves with time as new bone grows into its surface. The ingrowth of new bone is a process that takes time (4 -12 weeks), and the ingrowing bone should be protected from undue stresses during this period.

Originally, the surgeons believed that the patient must avoided loading of the cementless hip to achieve good ingrowth of the bone into the surface layer of the total joint prosthesis. Many surgeons do not adhere to this view longer. Here follow some reasons why:

Studies showed that in cementless total hip prostheses bone ingrowth fixation reliably occurs whether or not a partial or full weight-bearing postoperative protocol is followed. (Woolson 2002)

Moreover, studies demonstrated that even patients who were learned the "partial weight bearing" with crutches by their PT still put much more weight on their hips than learned, without knowing it. (Tveit 2001)"
