Introduction Foot Drop It is unusual to damage any major nerves or blood vessels. However, a nerve maybe stretched or damaged during surgery (this is called nerve palsy). This can result in a weakened lower leg or a foot that drops down, over time nerve injuries may improve. This complication is rare; occurring in less than 1:1000 patients. Loosening of the prosthesis Hip replacements do wear and some will require replacing. Wear or loosening of the components may occur between 10-15 years after surgery; this can be accelerated in excessive activity or obesity. Revision operations can usually be performed; however the results may not be as good as the initial operation and the risks or complications are greater. Difference in leg length Your surgeon will do their best to ensure that your leg length is equal, however sometimes this is not always possible as arthritis or wear and tear may have destroyed some of your bone, which could cause your operated leg to become shorter. This may result in you needing to wear a raised shoe or insole. 8
