Patellofemoral arthroplasty yielded low 30-day reoperation, readmission rates
Published results showed patients who underwent patellofemoral arthroplasty experienced low 30-day readmission and reoperation rates, with older age and elevated BMI identified as risk factors for adverse perioperative outcomes.
Ran Schwarzkopf, MD, associate professor in the department of orthopedic surgery at NYU Langone Health, and colleagues collected perioperative outcomes and 30-day postoperative complications of 1,069 patients who underwent patellofemoral arthroplasty from 2010 to 2015. Researchers also analyzed patient demographics and comorbidities to determine risk factors for postoperative complications.
Results showed patients had 30-day readmission and reoperation rates of 4.3% and 1.5%, respectively. Researchers identified bleeding requiring transfusion (11.7%), urinary tract infection (0.8%) and deep vein thrombosis (0.8%) as the leading complications among patients.
Patients who were younger had an increased incidence of superficial wound infection, while patients who were older experienced longer hospital stays, readmission, bleeding requiring transfusion, urinary tract infection and pneumonia, according to results. Researchers found longer operation time and deep vein thrombosis were associated with male sex, and a greater incidence of bleeding requiring transfusion was associated with female sex. Results showed an association between elevated BMI and longer hospital stays, greater total operation time and bleeding requiring transfusion. Readmission was associated with “non-white” race, researchers noted.
“Our study demonstrates a low rate of 30-day reoperation and readmission in [patellofemoral arthroplasty] PFA patients in line with those reported for [total knee arthroplasty] TKA patients, with similar risk factors for readmission like older age and increased BMI. Furthermore, longer operative times and longer hospital stay,” Schwarzkopf told Healio Orthopedics. “This information can help surgeons in proper patient selection for PFA as well as information to share with their patients during their surgical discussion and shared decision-making.”
