초록

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.

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.
