– See: – Medial Approach: – Post Operative Care and Compications: – Discussion: – oblique frx that begins near intercondylar eminence & extends to cortex of medial or lateral tibial flare; – total depression is similar to Type IV Frx – TDF of medial … Read more
– Discussion: – anterior longitudinal incision allows full exposure of the proximal tibia; – this incision allows exposure of both medial & lateral aspects of joint w/o the necessity for large skin flaps; – this incsion has advantage that it leaves strong cuff of fibrous … Read more
– Tibial Component Preparation: – ACL is resected, w/ or w/o PCL preservation; – Extramedullary Guides – alignment is made w/ jig parallel to ant crest of tibia shaft. – referencing was taken off the lateral tibial plateau. – Proximal Tibial Resection – Determine appropriate Posterior Slope – Depth of Tibial … Read more
– TKR Surgical Technique: – extramedullary guides – proximal tibial resection: – posterior slope of the tibial component: – depth of tibial cut: – Effect of the tibial cut on subsidence following total knee arthroplasty. – joint … Read more
– Trial Components: – component fit: – evaluate femoral and tibial trial components and determine areas that will need additional cement; – flexion & extension gaps – range of motion: use the largest polyethylene spacer that allows full extension; … Read more
– Optimize the Exposure: – it is important to fully expose the proximal tibial surface inorder to avoid iatrogenic injury to the collateral ligaments, the PCL, or even the posterior neurovascular structures; – soft tissue stripping: (see medial and lateral capsular exposure) … Read more
– Techique: – preparation and exposure for the proximal tibial cut: – hyperflexion of the knee to allows the vessels to fall more posteriorly; – curved knee retractors are positioned anterior to mid-coronal plane, so that patella tendon and MCL will not … Read more
