QTPB 자가건 ACL 재건에서 부분두께 건과 직사각 터널은 원형 터널보다 초기 공여부 부담을 줄일 수 있을까?
두 군 모두 안정성·임상 점수가 개선됐으며 군 간 수술 후 유의한 차이는 없었습니다.

이 연구가 확인한 것은 무엇인가요?
두 군 모두 안정성·임상 점수가 개선됐으며 군 간 수술 후 유의한 차이는 없었습니다.
개별 환자의 치료 결정에 바로 적용할 수 있나요?
후향적·단기 비교입니다. 직사각 기법은 한 수술자, 원형 기법은 다른 두 수술자가 선택했으며 채취한 이식건 두께도 달라 기법 자체 효과를 분리하기 어렵습니다. 단기 유의차 없음이 장기 재파열 위험의 동등성을 입증하지 않습니다.

BACKGROUND
Rectangular tunnel and graft have been recently designed to closely resemble the native anatomy in anterior cruciate ligament reconstruction (ACLR). This study was performed to compare the short-term clinical outcomes between rectangular and round femoral tunnels in ACLR using quadriceps tendon-patellar bone (QTPB) autografts.
METHODS
A total of 78 patients who underwent primary ACLR with QTPB autografts performed by three senior surgeons and had at least 1 year of postoperative follow-up were retrospectively reviewed. Patients who underwent rectangular tunnel ACLR (n = 40) were compared to those treated with the conventional round tunnel ACLR (n = 38). Outcomes including knee stability, clinical scores, quadriceps strength, associated complications, postoperative knee range of motion, and cross-sectional area of the graft were assessed.
RESULTS
Significant improvements in knee stability and clinical scores were observed after surgery in both groups (all p < 0.001). The postoperative measurements of knee stability and clinical scores were not significantly different between the two groups. Knee extension strength deficit at 60°/sec was significantly less in the rectangular tunnel group than in the round tunnel group at postoperative 6 months (41.7% vs. 48.9%, p = 0.032). The cross-sectional area of the partial-thickness QTPB graft was approximately 60% of the full-thickness QTPB graft.
CONCLUSIONS
In the short-term, rectangular tunnel ACLR was comparable to round tunnel ACLR with QTPB autograft despite the smaller cross-sectional area. Additionally, the rectangular tunnel ACLR allowed partial-thickness grafting technique, which could subsequently reduce early donor site morbidity.
