Abstract
Introduction
A comprehensive met-analysis of anterior knee pain post intramedullary nailing of the tibia was performed by Katsoulis et al in 2006. The principle findings were that 47.4% of patients had anterior knee pain at 2 years post tibial nailing. Worse results were found following a patella tendon splitting approach when compared with a medial para-patellar tendon approach. These conclusions were drawn from 20 studies including 1460 patients.
Currently both approaches to the proximal tibia for nailing are used at JCMH Blanchardstown. A retrospective study was performed to compare the results of tendon splitting and tendon sparing approaches to tibial nails and to compare the results of JCMH with those stated in literature.
Method
Patients who underwent tibial nailing in 2007 and 2008 were identified using the hospital coding system. Those patients who were treated under the care of Mr Kenny had a medial para-tendinous approach and those treated the care of Mr O'Flanagan and Mr Keogh had a tendon splitting approach. Apart from the approach the nailing technique using the Trigen Knee Nail and the post operative physiotherapy protocol were identical.
Follow up included questions regarding knee pain and return to previous function. Specifically: Knee pain that affects daily life, Knee pain on kneeling, Knee pain on ascending or descending stairs, Return to work and Return to sports or active hobbies.
Results
61 patients were treated with intra-medullary nailing between 2007 and 2008 43 were available for follow for the purposes of this study (70 %). 25 had nails inserted via a tendon splitting approach and 18 via a tendon sparing approach. Only 5% of patients had knee pain that affected daily life, 16 % had pain on kneeling, 90% of patients who were previously at work returned to work and 75% of patients who were previously engaged in sports were able to return to these activities.
Discussion
These results are significantly better than the figures stated in literature in terms of knee pain, return to work and sports. There was no significant difference between the 2 approaches to the tibia again in contradiction of available literature.
