Data Sources
The State Ambulatory Surgery Databases (SASD) and the State Inpatient Databases (SID) are administrative claims databases maintained by and publicly available from the Healthcare Cost and Utilization Project, which is managed by the Agency for Healthcare Research and Quality. These databases contain complete records for each available state for ambulatory surgical cases and inpatient hospital admissions, respectively. Descriptions of patient visits include variables such as patient age, sex,
Patient Demographic Characteristics
A total of 7,351 patients met the inclusion criteria for this study. Fifty-nine percent of patients were female patients, and 34% of patients were aged younger than 40 years (Table 1). Osteoarthritis and obesity diagnoses were present in 9.6% and 2.5% of cases, respectively. Twenty-seven percent of patients underwent hip arthroscopy at low-volume institutions compared with 42.4% at medium-volume centers and 30.6% at high-volume centers.
Rate of THA Conversion
Overall, 12.4% of patients had undergone primary THA within
Discussion
This retrospective population-based analysis of over 7,000 patients undergoing hip arthroscopy shows that older patients and patients with osteoarthritis and obesity have an increased rate of conversion to THA within 2 years. Higher-volume arthroscopy hospitals appear to have a reduced rate of patients undergoing THA conversion.
The current literature shows overall good results in patients who undergo hip arthroscopy, although many studies tend to focus on younger patients.11, 15, 16, 17, 18
Conclusions
Hip arthroscopy is performed in patients of various ages, including middle-aged and elderly patients. Older patients have a higher rate of conversion to THA, as do patients with osteoarthritis or obesity.
