Roberts Conference
July 21, 2005
History
64 year old male 6 yrs s/p Left Knee Arthrodesis following
TKA Significantly short on affected side
2 falls resulting in Hip Fractures
Successful TKA on Right
Operative Planning
Patient Requesting TKA
ESR, CRP and WBC all Normal
No Swelling or external evidence of infection
Conversion Athrodesis to TKA Kreder et. al: 18 knees 28% failure (infection,
component failure) Cameron and Hu: 17 knees 53% failure (tibial
component loosening, ligamentous laxity, quad rupture, wound breakdown, repeat athrodesis)
Kim et. al: 30 knees 53% failure; mean flexion 75 deg, 9 deg extension deficit
Henkel et. al: 7 knees 29% failure; 71% re-operation; most with increased pain on walking
Warner: Three phase “Judet quadricepsplasty” to mobilize extensor mechanism.
