All right, good afternoon everyone, thanks for giving us the opportunity to present our work. I'm stepping in for Danielle. We have nothing relevant to disclose. So as has already been previously discussed, lateral patella instability occurs at a very high instance, especially in female and adolescent top patient population. MPFL reconstructions widely utilize a reliable method to treat these recurrent patella instability patients. Despite these differences, we have found a crossover-critical literature in patient-reported outcomes. However, this has not been looked at for patella instability. So the purpose of our study was to investigate whether pain, function, satisfaction, and return to play differed between the sexes after MPFL reconstruction for patella instability. We hypothesized that female patients would have worse post-op outcomes compared to their male counterparts following reconstructions. Our methods, this is a retrospective review of about 131 patients, or 141 knees, who underwent MPFL reconstruction for a 10-year period at our institution, minimum 12-month follow-up would be included at all comers, including any concomitant procedures such as tibial tubercle osteotomies. Patients were contacted, completed outcome scores, including BAS, Kajala, we curate about return to play, time and rate in their level as well. We also looked at psychological readiness to return to sport. Demographically, our population was mostly female, about 69.5% compared to 30% male. There are no significant differences in terms of age or mean follow-up, with follow-up being roughly 45 months. Concomitant procedures, similarly, no significant differences were found. We also looked at recovery rates of TTOs, chondroplasties, and other procedures. In terms of our outcomes, there are no significant differences found between dyslexia in terms of BAS at rest, Kajala score, or mean satisfaction. Both groups have been equally satisfied with their outcome. Female patients tended to want to undergo the procedure again compared to their male counterparts, but this is not found to be significant. In terms of recurrent instability, again, no significant differences, although the trend will be a little bit higher in our female patients. Here's where we found some significant differences in terms of return to sport. So return to sport rate was significantly higher in our male patients compared to the female patients, while reported BAS during their sport activities was significantly lower in the male patients compared to the female patients. The psychological readiness of return to sport after MPFR reconstruction was found to be significantly higher in our male patients, with a score of 56 being determined to being psychologically ready. So none of the female patients really met that, according to this mean. Similar to all other retrospective studies, we had some limitations. Our follow-up rate was roughly 77.4%. We were underpowered to determine any significant differences between gender. We need a very large cohort to determine those differences. We did not account for any degrees of any preoperative morphological measures, such as patella height, trochlear dysplasia. So in conclusion, what we found is that female patients had worse clinical outcomes than males undergoing MPFL reconstruction, with significantly lower rates of return to play, BAS scores during sport, and MPFL-RSI scores. However, interestingly, our female patients were more willing to undergo the procedure again and demonstrate a similar satisfaction with the procedure versus our male patients. Thank you.
Video Summary
This video summarizes a study on the outcomes of MPFL reconstruction for treating patella instability, specifically looking at differences between male and female patients. A retrospective review of 131 patients who underwent MPFL reconstruction was conducted, and patients were contacted for outcome scores and information on return to play. The results showed that there were no significant differences in overall outcomes, satisfaction, or recurrent instability between male and female patients. However, male patients had a higher rate of return to sport and lower BAS scores during sport activities. Female patients were more willing to undergo the procedure again. The study had limitations and further research is needed. No credits were mentioned in the video.
