Summary
This study describes a lateral parapatellar approach for knee arthrography, highlighting its advantages over the more painful ventral approach. The ventral route is reserved for cases with complete suprapatellar plica.
Area of Science:
- Orthopedic Surgery
- Diagnostic Imaging
Background:
- Knee arthrography is a key diagnostic imaging technique for evaluating intra-articular knee pathology.
- Accurate needle placement is crucial for successful knee joint opacification and diagnostic yield.
Purpose of the Study:
- To describe and recommend the lateral parapatellar approach for knee puncture in arthrography.
- To compare the pain and feasibility of the lateral parapatellar versus the ventral approach.
Main Methods:
- A detailed description of the technique for performing knee puncture via a lateral parapatellar approach.
- Comparison of patient-reported pain and procedural success between the lateral parapatellar and ventral approaches.
Main Results:
- The lateral parapatellar approach is presented as a feasible and effective method for knee arthrography.
- The ventral approach is associated with increased pain and is indicated only in specific anatomical situations.
Conclusions:
- The lateral parapatellar approach is the preferred method for knee puncture during arthrography due to lower pain levels.
- The ventral approach should be reserved for cases where the lateral route is contraindicated, such as complete suprapatellar plica.
