In Jeong 2025 et al., on contoured saw guide vs jig, what was a key outcome in terms of osteotomy *inclination* on cadaver limbs?
A. TPLO with the contoured saw guide had greater deviation in inclination.
B. TPLO with the jig had more accurate inclination angle.
C. Contoured guide showed more accurate inclination angle (1.2° vs. 4.3°).
D. Both techniques achieved similar inclination angles.
E. TPLO with the guide required jig for accurate inclination.
Answer: Contoured guide showed more accurate inclination angle (1.2° vs. 4.3°).
Explanation: The contoured guide significantly reduced osteotomy inclination deviation, improving perpendicularity (p = .008).
In Jeong 2025 et al., on contoured saw guide vs jig, what was the effect of each on *postoperative tibial plateau angle (TPA)*?
A. Contoured guide achieved significantly lower TPA.
B. Jig group had more accurate TPA.
C. TPA was equivalent across both groups (~6–7.6°).
D. Contoured guide consistently undercorrected TPA.
E. Jig group consistently overcorrected TPA.
Answer: TPA was equivalent across both groups (~6–7.6°).
Explanation: Despite improved cutting accuracy, TPA outcomes were statistically similar between techniques (p = .15).
In Jeong 2025 et al., on contoured saw guide vs jig, which statement is correct regarding *osteotomy torsion*?
A. Jig-assisted TPLO had less torsional deviation.
B. Contoured guide resulted in greater torsion in both models.
C. Torsional angles were the same in both groups.
D. Contoured guide reduced torsion significantly in both bone models and cadavers.
E. Torsional data was not collected.
Answer: Contoured guide reduced torsion significantly in both bone models and cadavers.
Explanation: Contoured guide improved torsional precision (e.g., 257 vs 2573 pixels in bone models; p < .001).
In Jeong 2025 et al., on contoured saw guide vs jig, what was observed regarding *surgical time*?
A. Contoured guide shortened both osteotomy and application times.
B. Jig required more time due to pin placement.
C. Contoured guide lengthened procedure significantly.
D. No difference in device or osteotomy time was found.
E. Contoured guide required fluoroscopic assistance, increasing time.
Answer: No difference in device or osteotomy time was found.
Explanation: Both device application and osteotomy time were statistically similar (p > .05).
In Jeong 2025 et al., on contoured saw guide vs jig, what best describes *medial cortical damage* outcomes in bone models?
A. Both methods caused similar cortical damage.
B. The jig-assisted group had lower medial cortical damage.
C. Contoured guide caused more medial damage due to slippage.
D. Contoured guide caused significantly less damage (247 vs. 1866 pixels).
E. Medial damage was not assessed in bone models.
Answer: Contoured guide caused significantly less damage (247 vs. 1866 pixels).
Explanation: The contoured saw guide minimized saw blade slippage, leading to lower iatrogenic cortical injury (p < .001).
