Comparison of a Short Uncemented Femoral Stem to a Similar Standard Uncemented Femoral Stem

Randomized Controlled Trial Comparing a Short Uncemented Femoral Stem to a Similar Standard Uncemented Femoral Stem

This randomized controlled trial will compare patients receiving a standard uncemented femoral stem with patients receiving an identically designed short uncemented femoral stem.

This randomized controlled trial will compare patients receiving a standard uncemented femoral stem with patients receiving an identically designed short uncemented femoral stem.

Patients will be randomized a few days before the operation. At the time of surgery, the surgeon will use the relevant implant. Patients will be followed up for 5 years after surgery. The main outcome criteria is the stem subsidence measured radiographically with a dedicated software.

Inclusion Criteria:

• hip osteoarthritis requiring a total hip replacement
• >18 years old
• agrees to participate

Exclusion Criteria:

• total hip replacement not indicated
• general anesthesia contraindicated
• previous surgery on the ipsilateral femur
• follow-up not possible
