  1. Osteotomies About the Knee Lyon, France Oct. 2011 Mark Sanders, MD FACS The Sanders Clinic for Orthopaedic Surgery and Sports Medicine Houston, Texas USA

  2. Disclosures • None to report

  3. “Orthopaedics” • Derived from Greek • orthos ("correct," "straight") • paideion ("child") -Nicholas Andry, Orthopaedia: or the Art of Correcting and Preventing Deformities in Children, 1741.

  4. Patient #1 • 28 y/o F nurse, previously athletic, c/o bilat multidirectional patella femoral instability, L > R • Multiple previous surgeries left knee • Lateral retinacular release x2 • Medialization osteotomy of tibial tubercle • Hardware removals, fasciotomy, “cleanouts” • Physical Examination • Increased femoral anteversion • Increased tibial external torsion • Medial patella instability

  5. Pre-op

  9. Computerized Tomography Results • Femoral Anteversion: 50° R, 35° L (Normal 9-22° - D. Paley) • Tibial External torsion: 34° R, 39° L (Normal 18-28° - D. Paley) • TT-TG: 10mm R, 7mm L (Ideal tracking: 10-15mm - H. DeJour)

  10. Synchronous Surgical Treatment • Spinal/epidural anesthesia • Two lateral skin incisions • 20° proximal femoral external rotation osteotomy • 15° proximal tibial internal rotation osteotomy • 6mm laterally directed tibial tubercle osteotomy • Distal ITB based LPFLR • Immediate unrestricted active and active assisted hip, knee, and ankle motion • 10 kg weight bearing with crutches for 6 wks until early union determined • Bony union, off crutches at 3 months

  11. 5 mos. post-op

  15. Hardware removal- 5 mos. post-op L

  16. Hardware removal- 5 mos. post-op

  17. Highly Satisfied Patient • No further medial or lateral patella instability • Returned to light sports • Couldn’t wait to have Proximal Femoral Plate out • Scheduled for opposite side surgery over Christmas

  18. Take Home Messages • Repair/Reconstruct every deformity at one surgical sitting • Epidural and multimodal analgesia • Immediate active and active-assisted motion without CPM • Early return to function • Young people want hardware out, especially Proximal Femoral Plate

  19. Patient #2 • 24 y/o M, treated for congenital deformity of the opposite femur. Underwent femoral epiphysiodesis at Children’s Hospital • Currently with two previous failed allograft ACLRs • Physical Exam –Normal femoral and tibial version • Genu Valgus deformity • Asymmetric Hyperextension • PCL, PLC, MCL intact • 4+ Anterior instability

  20. Pre-op mLDFA 76.5º mLDFA 89.6º

  21. Pre-op RT aPDFA 97.7º Normal Values aPDFA : 79 – 87º aPPTA : 77 - 84º Note: Anterior tibial subluxation RT aPPTA 75.4º

  22. Synchronous Surgical Treatment • Long lateral skin incision • Opening wedge biplanar DFO for correction of 10° distal extension and 10° valgus deformity, using Freeze dried bone wedges and lateral TomoFix™ • Joint leveling biplanar HTO to decrease adverse tibial slope, and stabilized with medial and lateral TomoFix™ • ACLR deferred until tibial and femoral hardware could be safely removed

  23. 6 wks post-op RT mLDFA 89.5º

  24. 6 wks post-op RT aPDFA 84.2º Normal Values aPDFA : 79 - 87º aPPTA: 77 - 84º RT aPPTA 79.3º

  25. Pre-op 6 wks post-op

  26. This is a work in progress • Immediate active and active-assisted knee motion in combination with multimodal and epidural analgesia considerably decreases Perioperative pain and morbidity • Post-op Lachman’s decreased from 4+ to 2+ • I will show further follow-up X-rays in Davos in 2012

  27. Patient #3 • 34 y/o M plant worker, previously athletic, c/o constant medial knee pain. Reportedly needs TKA. • 9 previous surgeries, L knee • Lateral retinacular release • Multiple arthroscopies and “clean outs” • Repair of quad tendon rupture • Physical Examination • Normal femoral and tibial version • Genu varum, medial joint line tenderness • Medial patella femoral instability

  28. Pre-op R

  29. Pre-op • R mLDFA 95° • L mLDFA 94° ºº

  30. Synchronous Surgical Treatment • Long lateral skin incision • Opening wedge biplanar DFO for correction of 9° distal varus deformity, using Freeze dried bone wedge and opposite sided medial TomoFix™ applied medially • Distal ITB based LPFLR • Epidural analgesia and multimodal pain management • Immediate active and active assisted unrestricted motion of hip, knee, and ankle • 10 kg weight bearing with crutches for six weeks until early union determined

  31. 8 wks post-op R

  32. 8 wks post-op mLDFA 85º

  33. Pre-op 8 wks post-op

  34. This too is a work in progress, but... • Varus at the femur occurs more commonly than is generally believed (Van Heerwarden) • Correction is best applied at the CORA • Correction at another area can lead to joint line obliquity • Alignment is of primary importance - nothing we do succeeds without it.
