General Information
Knee arthritis can interfere with your enjoyment of sex. Positions such as standing and kneeling can cause discomfort to the point where you’re not interested in sex. If you’re taking narcotic pain medicine, these might cause drowsiness or interfere with arousal. You might be tired and fatigued from dealing with aching, swollen, or stiff knees.
Once you’ve made the decision to move forward with knee replacement, you might be anxious to return to normal activities you’re used to enjoying, including sexual relations.
