Abstract
Purpose: The purpose of this study is to evaluate the arthroscopic findings in patients who presented with persistent lateral elbow pain despite conventional conservative measures, with special regard to diagnosis specific results. The controversy regarding the etiopathogenesis, whether intraarticular, extraarticular or both continues to exist.
Method: This is a retrospective review of 280 arthroscopies of elbow in 262 patients over a period of 6 years with a minimum follow-up of 6 months. All of them are therapeutic procedures involving ECRB release, excision of plica, synovectomy or debridement of the joint. The functional outcome was assessed and recorded independently by two experienced upper limb physiotherapists using the Mayo elbow performance score.
Results: Dominant hand was involved in 68% of the cases. The average age was 54 years. Isolated pathology such as common extensor inflammation was identified in 138 (49%), synovial plica in 24 (8%) and degenerative changes confined to lateral compartment with normal appearance of articular cartilage of medial compartment is noted in 31 (11%). In the rest mixed pathology with various combinations were identified.
Conclusion: Good to excellent results were seen in those with isolated common extensor inflammation and poor outcomes were noted in 20 (7%) of patients and the common intraoperative finding seen was degenerative changes of radiocapitellar joint. This was found to be statistically significant.
