Patients with patella instability are treated surgically or conservatively with physical therapy to minimize redislocation risk and restore function. <jats:italic><jats:bold>Clinical Question<\/jats:bold>:<\/jats:italic> In individuals with a patella dislocation, how does treatment (conservative therapy versus medial patellofemoral ligament [MPFL] surgery) affect redislocation rates and patient-perceived function? <jats:italic><jats:bold>Summary of Key Findings<\/jats:bold>:<\/jats:italic> This critically appraised topic included 3 studies assessing outcomes in individuals with patella instability treated with MPFL surgery or conservative management. Outcomes included comparing redislocation rates and Kujala scale perceived knee function between participant groups. Surgery included MPFL reconstruction (MPFL-R) in 1 randomized controlled trial and 1 prospective controlled trial and MPFL repair in another randomized controlled trial. Conservative treatment included physical therapy and bracing. All 3 studies demonstrated significantly lower redislocation rates in individuals managed with surgery versus conservative treatment. Reported knee function was significantly higher in the MPFL-R group compared with individuals conservatively managed at 2-year follow-up but not at 1\u00a0year. No significant difference in knee function was present between individuals receiving MPFL repair or conservative management at a 2-year follow-up. <jats:italic><jats:bold>Clinical Bottom Line<\/jats:bold>:<\/jats:italic> There is moderate-level evidence to support a significant decrease in patella redislocation rates in individuals managed with MPFL surgery compared with conservative treatment. The reviewed studies suggest a significant improvement in patient-perceived knee function at 2\u00a0years following MPFL-R but no difference at 1\u00a0year following MPFL-R or 2\u00a0years after MPFL repair. <jats:italic><jats:bold>Strength of Recommendations<\/jats:bold>:<\/jats:italic> Grade B evidence supports lower patella redislocation rates with MPFL surgery compared with nonsurgical treatment. Furthermore, this evidence suggests a potential benefit in perceived knee function 2\u00a0years after MPFL-R compared with conservative management.<\/jats:p>","DOI":"10.1123\/jsr.2023-0426","type":"journal-article","created":{"date-parts":[[2024,9,10]],"date-time":"2024-09-10T18:36:51Z","timestamp":1725993411000},"page":"163-170","source":"Crossref","is-referenced-by-count":1,"title":["Minimizing Redislocation Rates and Restoring Function After Patella Dislocation: A Critically Appraised Topic"],"prefix":"10.1123","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7202-2896","authenticated-orcid":true,"given":"Matthew","family":"Senese","sequence":"first","affiliation":[{"name":"Sports Medicine and Performance Center, The Children\u2019s Hospital of Philadelphia, Chalfont, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronika","family":"Smith","sequence":"additional","affiliation":[{"name":"Miami Valley Hospital Huber Heights Physical Therapy, Huber Heights, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"4","key":"r1","series-title":"Am J Sports Med","doi-asserted-by":"publisher","first-page":"472","DOI":"10.1177\/03635465000280040601","article-title":"Characteristics of patients with primary acute lateral patellar dislocation and their recovery within the first 6 months of injury","volume":"28","author":"Atkin DM","year":"2000","unstructured":"Atkin DM, Fithian DC, Marangi KS, Stone ML, Dobson BE, Mendelsohn C.
