슬개골을 치환하지 않은 mobile-bearing TKA에서 기존 슬개골 연골병변의 정도와 위치가 결과와 관련될까?
모든 추적 시점에서 연골병변의 등급이나 위치에 따른 PROMs의 유의한 차이가 없었습니다.

이 연구가 확인한 것은 무엇인가요?
모든 추적 시점에서 연골병변의 등급이나 위치에 따른 PROMs의 유의한 차이가 없었습니다.
개별 환자의 치료 결정에 바로 적용할 수 있나요?
슬개골을 보존한 mobile-bearing TKA군의 결과입니다. 비치환과 치환을 무작위 비교하지 않았으며 유의차 없음이 두 치료의 동등성을 입증하지 않습니다.

BACKGROUND
During total knee arthroplasty (TKA), patellar retention is performed when the cartilage is fairly well preserved and the thickness of the patella is relatively thin. However, clinical outcomes of the non-resurfaced patella in TKA according to the cartilage status are lacking in the literature. The purpose of this study was to compare patient-reported outcome measures (PROMs) according to the grade and location of the patellar cartilage lesion in TKA patients.
METHODS
The outcomes of 165 osteoarthritis patients (186 knees) who underwent cemented mobile-bearing TKA without patellar resurfacing were assessed and classified according to the grade and location of the patellar cartilage lesion. PROMs using the Western Ontario and MacMaster Universities Osteoarthritis index, the Knee Society Score (Knee Society Function Score and Knee Society Knee Score), and the Hospital for Special Surgery score were evaluated preoperatively and at postoperative 2, 4, 6, and 8 years. The correlations between PROMs and the grade and location of the cartilage lesion were assessed. Additionally, radiologic outcomes including the patellar tilt angle and patellar height were assessed and their correlation with the grade of cartilage lesion was analyzed. Analysis of variance was used to determine statistical significance.
RESULTS
There was no significant difference between PROMs according to the grades and locations of cartilage lesions at any postoperative follow-up. Radiologic parameters also showed no significant differences according to the grades of patellar cartilage lesions.
CONCLUSIONS
The grade and location of the patellar cartilage lesion had no influence on clinical outcomes in mobile-bearing TKA with patellar retention at short- and long-term follow-up.
