Chi Square Analysis

Background: Patients are commonly evaluated at the emergency department (ED) with acute anterior cruciate ligament (ACL) tears, but providers without orthopaedics training may struggle to correctly diagnose these injuries. Hypothesis: It was hypothesized that few patients would be diagnosed with an ACL tear while in the ED and that these patients would be of lower socioeconomic status and more likely to have public insurance. Study Design: Cohort study; Level of evidence, 3. Methods: The 2017 State Ambulatory Surgery and Services Database (SASD) and State Emergency Department Database (SEDD) from the state of Florida were utilized in this study. Cases with Current Procedural Terminology code 29888 (arthroscopically aided ACL reconstruction [ACLR]) were selected from the SASD, and data from the SEDD were matched to patients who had an ED visit for a knee injury within 120 days before ACLR. Chi-square analysis was used to test for differences in patient and surgical variables between the ED visit and nonvisit patient groups. A generalized linear model was created to model the effect of ED visit on total cost for an ACL injury. Results: While controlling for differences in patient characteristics and concomitant procedure usage, a visit to the ED added $4587 in total cost ( P < .001). The ED visit cohort contained a greater proportion of patients with Medicaid (20.2% vs 9.1%), patients who were Black (18.4% vs 10.3%), and patients in the lowest income quartile (34.4% vs 25.0%) ( P < .001 for all). In the ED visit cohort, 14.4% of patients received an allograft versus 10.1% in the non-ED visit cohort ( P = .001) despite having a similar mean age. An ACL sprain was diagnosed in only 29 of the 645 (4.5%) patients who visited the ED. Conclusion: Utilizing the ED for care after an ACL injury was expensive, averaging a $4587 increase in total cost associated with ACLR. However, patients rarely left with a definitive diagnosis, with only 4.5% of patients who underwent ACLR being correctly diagnosed with an ACL tear in the ED. This additional cost was levied disproportionately on patients of low socioeconomic status and patients with Medicaid.

Background: There is a paucity of clinical information to guide the treatment of a combined anterior cruciate ligament (ACL) tear and Segond fracture. Purpose: To compare clinical outcomes, graft failure rates, and activity levels between patients undergoing ACL reconstruction (ACLR) with and without an untreated Segond fracture at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: This study included a group of patients with a combined ACL tear/untreated Segond fracture that was matched based on age, sex, body mass index, and graft type to a control group of patients with an ACL tear and no Segond fracture. All patients were treated with ACLR alone between the years of 2000 and 2015. The diagnosis of a Segond fracture, or bony avulsion of the anterolateral complex, was made by radiographic analysis. Data regarding the initial injury, surgical intervention, and physical examination findings were recorded. Clinical and functional outcomes were obtained using physical examination results, International Knee Documentation Committee (IKDC) subjective scores, and Tegner activity levels. Results: Twenty patients (16 male, 4 female) with a combined ACL tear/untreated Segond fracture with a mean age of 26.3 years (range, 13-44 years) were matched to a control group of 40 patients (32 male, 8 female) with an ACL tear and no Segond fracture with a mean age of 26.4 years (range, 13-47 years). The study group was followed for a mean of 59.1 months (range, 24-180 months) and the control group for a mean of 55.5 months (range, 24-120 months). The mean IKDC score was 86.5 (range, 54-100) for the study group compared with 93.0 (range, 54-100) for the control group ( P = .03). The graft rupture rate was 10% for both groups ( P = .97). The mean time to rupture was 33.0 months (range, 21-45 months) in the study group and 63.5 months (range, 39-88 months) in the control group ( P = .24). Patients in the study group had significantly more anteroposterior instability by preoperative Lachman testing than those in the control group (control group: 0 normal, 3 grade 1+, 37 grade 2+, 0 grade 3+; study group: 0 normal, 1 grade 1+, 10 grade 2+, 9 grade 3+; P = .0001). There was no significant difference between the 2 groups in regard to postoperative Lachman testing (control group: 35 normal, 3 grade 1+, 2 grade 2+, 0 grade 3+; study group: 17 normal, 3 grade 1+, 0 grade 2+, 0 grade 3+; P = .31). Patients in the study group had significantly more instability by preoperative pivot-shift testing than those in the control group (control group: 0 normal, 7 grade 1+, 33 grade 2+, 0 grade 3+; study group: 1 normal, 1 grade 1+, 11 grade 2+, 7 grade 3+; P = .0003). No significant difference was found between the 2 groups for postoperative pivot-shift testing (control group: 36 normal, 2 grade 1+, 2 grade 2+, 0 grade 3+; study group: 18 normal, 1 grade 1+, 1 grade 2+, 0 grade 3+; P = .61) or final Tegner activity level (median, 6). Conclusion: At midterm follow-up, patients undergoing ACLR with and without a Segond fracture had similar pivot-shift test results, graft failure rates, and activity levels. The IKDC score was statistically worse in the patients with a combined ACL tear/untreated Segond fracture, but the difference was less than the minimal clinically important difference for the IKDC score. These findings suggest that patients with a combined ACL tear/untreated Segond fracture can have comparable outcomes to patients with an ACL tear and no Segond fracture when treated with ACLR alone.

BackgroundThis updated systematic review reports data from 2009 on the prevalence, and risk factors, for knee osteoarthritis (OA) more than 10 years after anterior cruciate ligament (ACL) tear.MethodsWe systematically searched five databases (PubMed, EMBASE, AMED, Cinahl and SPORTDiscus) for prospective and retrospective studies published after 1 August 2008. Studies were included if they investigated participants with ACL tear (isolated or in combination with medial collateral ligament and/or meniscal injuries) and reported symptomatic and/or radiographic OA at a minimum of 10 years postinjury. We used a modified version of the Downs and Black checklist for methodological quality assessment and narrative synthesis to report results. The study protocol was registered in PROSPERO.ResultsForty-one studies were included. Low methodological quality was revealed in over half of the studies. At inclusion, age ranged from 23 to 38 years, and at follow-up from 31 to 51 years. Sample sizes ranged from 18 to 780 participants. The reported radiographic OA prevalence varied between 0% and 100% >10 years after injury, regardless of follow-up time. The studies with low and high methodological quality reported a prevalence of radiographic OA between 0%–100% and 1%–80%, respectively. One study reported symptomatic knee OA for the tibiofemoral (TF) joint (35%), and one study reported symptomatic knee OA for the patellofemoral (PF) joint (15%). Meniscectomy was the only consistent risk factor determined from the data synthesis.ConclusionRadiographic knee OA varied between 0% and 100% in line with our previous systematic review from 2009. Symptomatic and radiographic knee OA was differentiated in two studies only, with a reported symptomatic OA prevalence of 35% for the TF joint and 15% for PF joint. Future cohort studies need to include measurement of symptomatic knee OA in this patient group.PROSPERO registration numberCRD42016042693.
