Bone cement must penetrate the cancellous bone in order to achieve micro-interlock and successful long-term prostheses survival.
The cumulative survival with both reoperation and revision as the endpoint was better for the cemented long-stem prostheses with up to 3 years follow-up.
During the selected time period, there were 1,056 patients (534 males, 51%) operated with cemented long-stem prostheses in the register (1,073 hips).
We chose the Lubinus, Exeter, and Spectron cemented long-stem prostheses as a control group, as they comprise most of the cemented stems used in revision hip arthroplasty in Sweden (Swedish Hip Arthroplasty Register).
We have identified several methodological problems in the literature including a lack of observed long term prosthesis survival data, limited up-to-date UK based evidence and exclusion of patient and societal perspectives.

Oduwole et al. (2009) reported that due to possible bone loss, the potential need for augmentations, and use of long-stem prostheses, insertion of a new total knee arthroplasty (TKA) in the proper position can be technically demanding.
Stress-induced bone remodeling may compromise long-term prosthesis fixation and significantly contribute to loosening.
The long-stemmed prosthesis provides stable fixation and allows patients to start early movements and weightbearing [22, 45, 46].
It is also suggested that fractures resulting in prosthetic instability should be treated with a long-stem prosthesis extending at least 2 3 cortical diameters past the fracture site with consideration for rigid plate fixation [1, 7].
