Treatment Options for Septic Arthritis
Antibiotic Therapy
In cases of septic arthritis, antibiotic treatment is essential to combat the infection. Patients are typically administered antibiotics intravenously during their hospital stay, which may last for two weeks or longer. This method allows for a more immediate response to the infection, often improving symptoms within 48 hours. After discharge, a course of oral antibiotics is usually prescribed to ensure the infection is fully cleared.
Surgical Interventions
In some instances, surgical procedures may be necessary. If there is a significant buildup of pus in the joint, a procedure called aspiration is performed to drain the fluid. This can be done multiple times if needed. For deeper infections, such as those in the hip joint, open surgery may be required to effectively remove the infected tissue. In cases involving artificial joints, the prosthetic may need to be removed and replaced after the infection is resolved.
Supportive Treatments
Alongside antibiotics and surgery, supportive treatments play a crucial role in recovery. Pain management is often achieved through medications, and physical therapy is recommended to restore joint function and prevent stiffness. Gentle exercises can help maintain muscle strength around the affected joint, which is vital for long-term recovery.
