Choosing the X-ray side (left or right) orients the plan. https://osalign.com/marketing/landmarks-complete.jpg Step 3: four landmarks set; TPA calculated at 33.1°. https://osalign.com/marketing/saw-cut.jpg Step 4: a 24 mm radius blade (48 mm diameter) with a 54.0 mm arc, positioned over the proximal tibia. https://osalign.com/marketing/saw-cut-rotated.jpg Step 5: the rotated segment rendered live, with the resulting slope angle and arc length. https://osalign.com/marketing/plate-overlay.png Step 6: a 3.5 small TPLO plate templated on the rotated segment. https://osalign.com/guides/what-is-tplo-surgery/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/surgery-result.png A TPLO after surgery: the tibial plateau has been rotated to level it and fixed with a locking plate while the bone heals. https://osalign.com/marketing/landmarks-start.png A planning-quality radiograph: the whole tibia from stifle to tarsus, with a calibration marker in view. osAlign lists the four TPA landmarks in order and can auto-detect them for you to confirm. https://osalign.com/marketing/hero/plan.jpg The finished plan: functional axis, leveled plateau (3.5°), curved osteotomy, and a plate template, measured on a calibrated radiograph. https://osalign.com/guides/tibial-plateau-angle/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/guides/tpa-closeup.jpg TPA in osAlign: the plateau line (green), the functional axis (blue), its perpendicular (orange), and the angle between them, 33.1°. https://osalign.com/marketing/guides/landmarks-panel.jpg In osAlign all four landmarks are listed in order with their status; once all four are set, the TPA is calculated and can be saved to the case. https://osalign.com/marketing/landmarks-complete.jpg The full picture: the functional axis runs the whole length of the tibia, which is why the talus must be in the image. https://osalign.com/marketing/guides/plan-measurements.jpg After planned rotation the plateau reads 3.5°, alongside the osteotomy reference measurements. https://osalign.com/guides/tplo-planning-precision/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/guides/plan-measurements.jpg Measured, not estimated: osteotomy reference lines at 39.95 mm and 79.98 mm and a leveled plateau at 3.5°. https://osalign.com/marketing/calibration.png A 10 mm calibration line on the marker. The plan inherits the quality of this one line, so zoom in and place it carefully. https://osalign.com/marketing/guides/tpa-closeup.jpg TPA 33.1°: plateau line (green), functional axis (blue), and the 90° reference (orange). https://osalign.com/marketing/guides/saw-cut-closeup.jpg A 24 mm radius blade with a 54.0 mm arc, drawn at true size over the proximal tibia. https://osalign.com/marketing/guides/rotation-slope.jpg After rotation the panel reports the new slope (2.1°) and the arc distance to mark in surgery (13.0 mm). https://osalign.com/marketing/plate-catalog.png Choose the manufacturer, plate type, size, and side; the preview shows the measured plate outline before you add it. https://osalign.com/guides/ai-tplo-planning/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/landmarks-start.png One click on Auto-Detect Landmarks places all four TPA landmarks for the surgeon to review. https://osalign.com/marketing/landmarks-complete.jpg After detection: four landmarks, the functional axis, and a 33.1° TPA, ready for the surgeon to confirm or drag into place. https://osalign.com/marketing/workspace-tools.png The osAlign workspace: calibration, landmarks, saw cut, and plate tools sit next to the AI planning tools. https://osalign.com/guides/tplo-rotation-and-saw-blade-selection/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/guides/saw-cut-closeup.jpg A 24 mm radius blade drawn at true size with a 54.0 mm arc, positioned over the proximal tibia. https://osalign.com/marketing/saw-cut.jpg osAlign's saw cut tool: blade radius from standard sizes, arc length in mm, and curved edges to match the blade. https://osalign.com/marketing/saw-cut-rotated.jpg The rotated segment, the resulting slope (2.1°), and the arc distance (13.0 mm), measured on the image. https://osalign.com/guides/radiograph-calibration-for-tplo/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/calibration.png Calibration in osAlign: draw a line across a known distance on the marker, enter it, and apply. https://osalign.com/marketing/landmarks-start.png A planning-quality image: stifle to tarsus in one view, with the marker in the field. https://osalign.com/guides/tplo-plate-templating/ 2026-09-23 monthly 0.8 https://osalign.com/marketing/plate-overlay.png A 3.5 small TPLO plate templated on the rotated plateau segment, rotated 11° to follow the tibia. https://osalign.com/marketing/complete-plan.png The finished plan: plate template on the rotated segment alongside the plateau angle and osteotomy measurements. https://osalign.com/marketing/plate-catalog.png Preview the measured plate outline before adding it to the plan. https://osalign.com/how-it-works/ 2026-09-23 monthly 0.9 https://osalign.com/marketing/complete-plan.png A completed osAlign TPLO plan https://osalign.com/marketing/landmarks-complete.jpg Four tibial landmarks placed with the tibial plateau angle calculated https://osalign.com/marketing/saw-cut-rotated.jpg Osteotomy rotation preview showing the new plateau angle https://osalign.com/marketing/plate-overlay.png A true-size TPLO plate overlay on the radiograph https://osalign.com/pricing/ 2026-09-23 monthly 0.9 https://osalign.com/privacy/ 2026-09-23 yearly 0.3 https://osalign.com/terms/ 2026-09-23 yearly 0.3
