Owner assessed outcomes following elbow arthroscopy with or without platelet rich plasma for fragmented medial coronoid process

Abstract

ObjectiveDocument the outcomes of bilateral arthroscopic subtotal coronoidectomy for the fragmented medial coronoid process, quantify persistent lameness that required additional treatment (PRP), and document the outcomes of dogs that followed up with PRP injections.Study designRetrospective study.Sample populationOverall, 115 dogs underwent arthroscopy alone and 31 received PRP at least 6 weeks after arthroscopy. The owner's response rate was ~50% (73 dogs).MethodsCollected data included signalment, unilateral or bilateral clinical signs, intra-articular chondroprotective injection during the procedure, if PRP intra-articular injection was received postoperatively, and if it was received, the time from the initial surgery to administration was recorded. Outcomes were assessed via standardized owner questionnaires using the Liverpool Osteoarthritis in Dogs (LOAD) score, the Canine Brief Pain Inventory (CBPI) score, and the overall quality of life (QOL) assessment.ResultsApproximately 20% of the patients received PRP post-operatively due to persistent lameness following surgery. Similar pain scores were found between the two groups with an average of 11–13 LOAD score, 13–15 CBPI score, and good quality of life. Older animals at the time of surgery and those that received pain-relieving medications after the procedure were more painful and affected their functional outcome. PRP as an adjunctive therapy achieved a perceived good to excellent quality of life in ~90% of pets in this population.ConclusionArthroscopy and subtotal coronoidectomy followed by PRP, if needed, seemed to decrease pain, and improve lameness in the long term.Clinical significancePRP should be considered as adjunctive therapy in dogs with the limited response to arthroscopy alone.

Assessment of Outcome of Arthroscopic Subtotal Coronoidectomy in Treating Medial Coronoid Disease and Effect of Concurrent Autologous Conditioned Plasma in Dogs Using Force Plate Analysis

“…[24][25][26] A recent study by Matos Cruz and Mason in dogs with medial coronoid disease that underwent bilateral arthroscopic subtotal coronoidectomy followed by PRP injection found that older dogs had less favourable outcomes. 27 In their study, the average age was 26.1 months, which was considerably older than in our study. An age effect is unlikely in this study as both groups were similar in age and could be classified as young.…”

Outcomes of 15 dogs and two cats with metabone fractures treated with fluoroscopically guided normograde metabone pinning

“…20 In contrast, we used LOAD to assess function only at medium to long-term as well at final follow-up, similar to other studies. [43][44][45] LOAD questionnaire data was not collected at first presentation as all dogs showed severe lameness.…”

“…The LOAD questionnaire was developed to compare dogs prior to and after a certain treatment, for example whether or not a certain anti‐inflammatory improves signs of arthritis 20 . In contrast, we used LOAD to assess function only at medium to long‐term as well at final follow‐up, similar to other studies 43–45 . LOAD questionnaire data was not collected at first presentation as all dogs showed severe lameness.…”
