Evaluation of the Medial Parapatellar Knee Injection Technique
Repository

Identifier
clinicaltrials:NCT00712972
Description
The goal of our study is to present important anatomic considerations which should be
considered before knee injection is performed. Additionally, we have developed important
procedural augments to the traditional para-patellar injection techniques in order to exceed
the accuracy and safety previously reported for the infra-patellar approaches We have
developed an injection technique which mechanically is similar to current techniques
practiced and poses no additional risks or discomfort to the patient. The basis of our
technique and its success is through recognition of anatomic factors and avoidance of
possible iatrogenic injuries which exist when using other knee injection technique. The focus
of our study is to validate the clinical accuracy we have been obtaining using our technique
through fluoroscopically confirmed visualized confirmation of repeated intra-articular
deposit. Additionally we want to document the range of needle length we require to properly
access the knee joint in our population to substantiate the importance of needle length.
Needle length is a critical factor in obese patients whom have larger infra-patellar fat
pads.

Our hypothesis is that when using a 6 inch 22 gage needle for intra-articular knee injections
through the medial joint line approach, while utilizing the medial wall of the lateral
femoral condyle as an intra-articular stop point for needle insertion, the accuracy of
intra-articular deposit will exceed the values currently reported in the literature which is
approximately 75% success rate.

To prove this point we will be injecting 2 cc of radiocontrast dye into the joint space and
than immediatly view the joint flouroscopicly after the knee has been brought through 10
cycles of flexion and extension.
