Morbid obesity is considered to have a stronger association with complications after total knee arthroplasty (TKA). Although the impact of obesity coding errors has been previously reported, the extent of coding inaccuracies with respect to morbid obesity is unclear. Therefore, the purpose of this study was to assess (1) the utility of coding in identifying morbid obesity and (2) the effects of morbid obesity on 90-day complications after TKA when morbid obesity was defined by both body mass index (BMI) and International Classification of Diseases 9th edition (ICD-9) coding. ⋯ A higher rate of complications was noted when patients were defined as morbidly obese by ICD-9 as when defined by EMR-reported BMI. Although morbidly obese patients are more likely to have a code for obesity compared with obese patients, these patients may not be correctly identified as morbidly obese due to a lack of specificity in the codes. These errors may lead to inadequate reimbursements, and may also overestimate the effect of morbid obesity on complications.

The purpose of this study was to evaluate the clinical outcomes after arthroscopic management of irreducible posterolateral knee dislocation. Twenty-one patients with irreducible posterolateral knee dislocation were treated in our institution from January 2009 to May 2014. Inclusion criteria were as follows: (1) patients who underwent one-stage arthroscopic reduction combined with multiligament reconstruction or repair and (2) patients with a minimum 2-year follow-up. ⋯ The IKDC subjective score, Lysholm score, and Tegner score improved significantly postoperatively (p = 0.001) with a satisfaction rate of 84.6%. One-stage arthroscopic reduction combined with multiligament reconstruction or repair was an effective, reliable treatment for irreducible posterolateral knee dislocation. This is a case series with level of evidence as IV.
