Prospective study to determine restoration of posterior condylar offset and the risk of anterior femoral notching in total knee arthroplasty using posterior referencing technique (With Biomet, Vanguard Implant)
Journal Title: National Journal of Clinical Orthopaedics - Year 2018, Vol 2, Issue 4
Abstract
Objectivest: Otal knee replacement surgery has been definitive management for severe grade osteoarthritis. Literature shows that posterior referencing accurately restores posterior condylar offset relative to anterior referencing but there are chances of anterior femoral notching and anterior femoral notching in turn may lead to peri-prosthetic fracture. Various studies shows that anterior referencing technique affects the flexion gap tightness. This study is intended to assess the restoration of posterior condylar offset and the chances of anterior femoral notching in total knee replacement using posterior referencing technique by observing pre-operative and post-operative knee x-ray true lateral view. Methodology: This is a prospective observational study of 50 consecutive cases of knee joint osteoarthritis, Posterior condylar offset was measured using picture archiving and communication systems (PACS). Post-operative X-rays knee joint true lateral views were observed for anterior femoral notching. Results: In 49 knee replacements posterior condylar offset was restored within 0 cm to +0.3 cm. In one case pco increase beyond +0.3cm. In none of the cases pco decreased. In none of the cases anterior femoral notching was seen. Conclusion: This study concludes that in total knee replacement using posterior referencing technique, most of the cases posterior condylar offset is restored and chances of anterior femoral notching is negligible. Further studies needed with larger number of cases.

A study of functional outcome of distal tibial extra-articular fracture fixed with locking compression plate using MIPPO technique
Background: Distal metaphysical fractures of Tibia are difficult to manage due to its poor blood supply and limited soft tissue envelope. Most of these are managed surgically using closed reduction with IMIL nail, ORIF w...
Analysis of cases of distal tibial fracture managed with MIPPO technique
Background: Fracture of this bone is challenge for orthopedic surgeon as there is less muscular covering the bone. This leads to complications such as non- union, delayed union or dehiscence. The present study was conduc...
