Background: This study aims to compare the results between antibiotic therapy alone and combined with arthroscopic lavage in patients with low-grade pyogenic arthritis of the knee.
Methods: Patients with low-grade pyogenic arthritis of the knee were defined as those with symptoms of acute pyogenic arthritis but with a white blood cell count of 20,000 to 50,000/mm3 in the synovial fluid and a polymorphonuclear neutrophil level of 50% to 90%. We analyzed a total of 124 patients retrospectively. Patients treated using antibiotic monotherapy were categorized as Group A, and those treated using antibiotic therapy combined with arthroscopic lavage, as Group B. We compared parameters such as the duration of antibiotic injection, length of hospitalization, and recovery of the range of motion. Clinical outcome, measured as the Lysholm score and the visual analogue scale (VAS) score, was also compared.
Results: We found that the parameters duration of antibiotic injection, length of hospital stay, and recovery of range of motion of the knee were significantly better in Group A than in Group B. However, the clinical outcome, denoted by the Lysholm knee score and the VAS score, did not significantly differ between the two treatment groups.
Conclusion: We conclude that in patients with low-grade pyogenic arthritis of the knee early antibiotic therapy alone shows more satisfactory results than antibiotic therapy combined with arthroscopic lavage. Thus, our findings suggest that antibiotic monotherapy should be considered without any adjunct procedures such as arthroscopic lavage.
