Banks et al: A mismatch of planning and achieved tibial plateau angle in cranial closing wedge surgery: An in silico and clinical evaluation of 100 cases
Veterinary Surgery 1, 2024

🔍 Key Findings Summary

• Study Design: Retrospective study of 100 radiographs using in silico and clinical data
• Mean preoperative TPA: 28.6°, higher in small dogs than large (p = .02)
• Mean planned TPA (in silico): 7.6°, not achieving 5° target (p < .01)
• Median postoperative TPA: 5.5° overall; higher in small dogs (7°) vs large (4.5°) (p = .06)
• Postoperative ostectomy position: More distal than recommended; average = 8.6 mm
• Increased distalization → greater under-correction of TPA (p = .01)
• Most accurate correction occurred when ostectomy was ≤7.5 mm from patellar tendon
• Wedge angle categories (TPA-Pre minus 5–2°) were used based on pre-op TPA
