Results from this study demonstrated patients who had previous non-ACL arthroscopic procedures and those without prior surgery had similar clinical outcomes, survivorship and complications at long-term follow-up after total knee arthroplasty.
“In this large series of patients undergoing TKA, after previously having routine knee arthroscopies without ligamentous reconstruction, we found no difference in postoperative TKA clinical outcomes, range of motion [ROM], survivorship free of complications (particularly infection), and survivorship free of revision or reoperation,” Matthew P. Abdel, MD, told Healio.com/Orthopedics.
Abdel and colleagues performed a retrospective review of data for 1,140 patients who underwent 1,315 primary TKAs from 2003 to 2004. Previous arthroscopy was performed in 160 TKAs and were matched with 320 control patients who did not have prior surgery. The mean follow-up was 9 years. Investigators assessed original Knee Society scores, ROM, complications and survivorships.
Results showed that in patients who underwent arthroscopy, the mean KSS increased from 36 to 84. This measure went from 35 to 86 in control patients. Investigators noted the mean ROM preoperatively and postoperatively was not significantly different between patients who underwent arthroscopy vs. controls. At 5 years, both groups had similar survivorship free of complications. Infection was seen in two control patients and three patients who underwent arthroscopy. At 10 years, both groups had similar survivorship free of revision for aseptic loosening, revision for any reason and reoperation. – by Monica Jaramillo
