Abstract

We evaluated the change of quadriceps angle (QA) after tibial tuberosity transposition. Twenty-nine animals and 37 limbs of the total 62 case possibilities qualified for this study. The preoperative QA was $24.02{\pm}4.02$ in grade 2, $26.08{\pm}5.66$ in grade 3 and $30.25{\pm}7.41$ in grade 4. The postoperative QA was $21.25{\pm}3.24$ in grade 2, $19.16{\pm}3.92$ in grade 3 and $19.72{\pm}7.30$ in grade 4. The postoperative QA for all grades significantly decreased when compared with the preoperative QA (P < 0.05). However, the postoperative QA values were not within the normal range, although the dogs' prognosis remained good during the 4-month follow-up period. These results suggest that postoperative QA outside of the normal range may be allowed clinically.

내측 무릎골 탈구를 나타낸 개에서 경골결절 전위술 실시후 대퇴사두근각(QA)의 변화를 평가하였다. 내측 무릎골 탈구를 나타낸 전체 62 증례 중 실험조건에 맞는 37개의 다리를 조사대상으로 선정하였다. 술전 QA는 각각 grade 2에서 $24.02{\pm}4.02^{\circ}$, grade 3에서 $26.08{\pm}5.66^{\circ}$ 그리고 grade 4에서 $30.25{\pm}7.41^{\circ}$로 나타났다. 술후 QA는 grade 2에서 $21.25{\pm}3.24$, grade 3에서 $19.16{\pm}3.92$ 그리고 grade 4에서 $19.72{\pm}7.30$로 나타났으며, 모든 등급에서 술후 QA는 술전 QA에 비해 유의성 있게 감소되었다(P < 0.05). 4개월간 추적관찰한 결과 모든 증례는 술후 양호한 예후를 나타냈었으나, 술후 QA는 정상보다 높게 나타났다. 이러한 결과는 정상범위보다 큰 술후 QA는 임상적 예후와 관련성이 적을 것으로 생각된다.
