Preoperative knee-specific and generic patient-reported outcome measures were not affected by the presence of patellofemoral osteoarthritis among patients with medial or lateral OA, according to results from the Virtual EFORT Congress.

Using preoperative anterior-posterior and lateral/sunrise radiographs with Kellgren-Lawrence grade 3 or 4 and joint space width of less than 2.5 mm, Veronique Vestergaard, MD, PhD, and colleagues categorized 384 patients who underwent total knee arthroplasty for compartmental OA into a medial OA group, medial with patellofemoral OA group, lateral OA group, lateral with patellofemoral OA group, medial and lateral OA (bi-compartmental) group, or medial and lateral with patellofemoral OA (tri-compartmental) group.

“The KOOS, [EuroQol-5D] EQ-5D weighted and the EQ-5D VAS were collected [preoperatively] and 1 and 3 years postoperatively,” Vestergaard said in her presentation. “Multivariable regression models were used to adjust for potential confounders.”

Vestergaard noted patellofemoral OA had no effect on preoperative KOOS and EQ-5D scores. Patients with bi- and tri-compartmental OA had less pain preoperatively, higher daily function both preoperatively and 1 year postoperatively, and higher sports activity at 1 year postoperatively vs. patients with medial OA with or without patellofemoral OA, according to Vestergaard. She added patients with lateral OA with or without patellofemoral OA had more symptoms, more pain, lower daily function, lower quality of life and lower general health at 3 years postoperatively compared with patients with medial OA with or without patellofemoral OA.

“Patients with less common osteoarthritis patterns thus demonstrate surgical challenges,” Vestergaard said. “Further development of indications for and correct timing for TKA in different patient subgroups is warranted.”
