Surgical Treatment of Labral Tears: Debridement, Repair, Reconstruction.

PURPOSE OF REVIEW: With the rapid growth of hip arthroscopy over the past decade, new treatment paradigms as well as recognition of new disease states have sprung forth. The ability to perform complex arthroscopic procedures of the hip such as labral augmentation and reconstruction is essential for hip arthroscopists in the revision setting, with patient selection and indications for various labral treatments the key driver for improved short- and mid-term clinical outcomes. RECENT FINDINGS: Current techniques have been developed to address disease states where the labrum is either unstable, torn, deficient, or otherwise incompetent. Many early reports focused on the description of these techniques with new literature reporting short- and mid-term outcomes. A few of these have demonstrated improved outcomes with a contemporary arthroscopy with emphasis on capsule preservation and repair. Studies have demonstrated that labral repair has improved outcomes over labral debridement, with results of labral reconstruction in a revision approaching those of labral repair. In addition, newer reports have shown significantly improved outcomes and survivorship with capsule repair and therefore should be included in every hip arthroscopy.

Computer-Navigated Total Knee Arthroplasty Utilization.

Computer-navigated total knee arthroplasty (CN-TKA) has been used to improve component alignment, though the evidence is currently mixed on whether there are clinically significant differences in long-term outcomes. Given the established increased costs and operative time, we hypothesized that the utilization rate of CN-TKA would be decreasing relative to standard TKA in the Medicare population given the current health care economic environment. We queried 1,914,514 primary TKAs performed in the entire Medicare database from 2005 to 2012. Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes were used to identify and separate CN-TKAs. Utilization of TKA was compared by year, gender, and region. Average change in cases per year and compound annual growth rate (CAGR) were used to evaluate trends in utilization of the procedure. We identified 30,773 CN-TKAs performed over this time period. There was an increase in utilization of CN-TKA per year from 984 to 5,352 (average = 572/year, R (2) = 0.85, CAGR = 23.58%) from 2005 to 2012. In contrast, there was a slight decrease in overall TKA utilization from 264,345 to 230,654 (average = 4297/year, R (2) = 0.74, CAGR = - 1.69%). When comparing proportion of CN-TKA to all TKAs, there was an increase from 0.37 to 2.32% (average 0.26%/year, R (2) = 0.88, CAGR = 25.70%). CN-TKA growth in males and females was comparable at 24.42 and 23.11%, respectively. The South region had the highest growth rate at 28.76%, whereas the Midwest had the lowest growth rate at 15.51%. The Midwest was the only region that peaked (2008) with a slow decline in utilization until 2012. Despite increased costs with unclear clinical benefit, CN-TKA is increasing in utilization among Medicare patients. Reasons could include patient preference, advertising, proper of coding the procedure, and increased publicly available information about arthroplasty options.
