Abstract
Background: Total knee arthroplasty has been a treatment option for knee osteoarthritis since 1954. Recent evidence has identified various patient factors and prehabilitation strategies that may improve postoperative outcomes.
Objective: To evaluate the influence of patient factors and prehabilitation on postoperative outcomes.
Methods: The literature was reviewed from 1954 to 2012 using PubMed, CINAHL, and ProQuest.
Results: Strength, age, range of motion, pain, and expectations have the strongest influence. Obesity, timing, and gender have the least influence. Short-term prehabilitation using neuromuscular electrical stimulation and proprioception training may improve outcomes.
Conclusion: Patient factors and prehabilitation seem to be beneficial, but further research is needed.
