Compared with patients who have not undergone knee surgery, patients with previous knee surgery underwent total knee arthroplasty at a significantly younger age, especially men and those with a history of ligament reconstruction, according to study results.
Researchers reviewed data for 1,286 patients from a prospective total joint registry with a history of osteoarthritis or posttraumatic arthritis who underwent total knee arthroplasty (TKA) from 1998 through 2010. Data included patient age at the time of TKA, sex, body mass index, any previous knee surgery and the type of knee surgery, as well as patient questionnaire responses about history of knee surgery.
Overall, 29 percent of patients had a history of knee surgery, and men were significantly more likely to have had previous knee surgery than women (39 percent vs. 24 percent). Patients who had undergone previous knee surgery were significantly younger at the time of TKA; specifically, those with a history of ligament reconstruction underwent TKA at a significantly younger age than those with a history of other knee surgery, according to the researchers.
Women who had not had previous knee surgery underwent TKA at a significantly younger age compared with men; however, study results showed no difference in age between the sexes in those with previous knee surgery. The average interval from previous knee surgery to TKA was 13.1 years.
“Future research should investigate whether previous knee surgery affects the outcome of total knee arthroplasty; these factors could predict which patients are likely to need total knee arthroplasty following knee surgery, especially ligament reconstruction, and how to delay the need for total knee arthroplasty in patients who undergo knee surgery in adolescence and early adulthood,” the researchers wrote.
