Arthroscopy: How To Tell It's Time To Replace Your Knee

4. Risks Of Knee Surgery

Like all major surgeries, the risks should be outweighed by the benefits. Although safe, the major risks include infection and stiffness. Infection could result in the temporary removal of the knee replacement to be replaced with an antibiotic one for three months.
