Patients with septic arthritis do best if they have arthroscopic surgery soon after their symptoms develop, and also do well if the joint involved has fewer degenerative changes before infection.
Researchers from the University of Wurzburg in Germany found that degenerative changes, time interval between symptoms and surgery, and patient age were the key prognostic predictors following arthroscopic surgery.
The type of organism involved also influenced how many arthroscopic procedures were needed before the patient became free from infection.
There was also an indirect influence of the time between infection and surgery, which influenced intraoperative macroscopic appearance.
In the series that the orthopedic researchers looked at there were 78 knees, eight shoulders and three ankles. Follow-up evaluation was for an average of 2.5 years. The researchers looked at a series of 88 patients over a period of six years who were admitted with septic arthritis and treated at the university hospital’s orthopedic clinic.
The patients, who ranged in age from three months to 83 years with an average age of 48, were treated using keyhole surgery techniques.
The surgeons used arthroscopic joint debridement and the application of suction drains, combined with appropriate antibiotics and early functional treatment.
