Residual or unaddressed structural deformity of the hip and underlying osteoarthritis are commonly associated with failure after hip arthroscopy. Thorough patient evaluation with detailed characterization of structural hip anatomy and articular cartilage integrity are critical to the selection of proper surgical intervention and successful patient outcome.
The prevalence of low serum levels of vitamin D among patients undergoing orthopaedic surgery is very common. Given the importance of vitamin D in musculoskeletal health, such low levels may negatively impact patient outcomes.
Background: The opioid epidemic in the United States has placed increased pressure on physicians to engage in responsible opioid prescribing practices. However, surgeons currently have little information to guide their postoperative prescription decision-making. The purpose of this study was to assess opioid consumption after knee arthroscopy and identify preoperative factors that may predict higher opioid usage.Methods: A prospective observational study of 221 patients was conducted in patients undergoing outpatient knee arthroscopy for meniscal repair, partial meniscectomy, debridement, chondroplasty, or loose body removal. Participants recorded their daily opioid consumption in a postoperative pain diary. Total opioid consumption was calculated from counts of remaining pills at the 2-week and 6-week postoperative office visits. Variables, including age, sex, body mass index, smoking status, alcohol consumption, preoperative pain severity and duration, preoperative opioid usage, Patient-Reported Outcomes Measurement Information System (PROMIS) scores, and the Connor-Davidson Resilience Scale, were evaluated for an association with opioid consumption.Results: Total opioid consumption ranged from 0 to 188 pills, with a median of 7 pills (hydrocodone 5-mg equivalents).Forty-six percent of patients took £5 pills, 59% took £10 pills, and 81% took £20 pills. Fifty-six percent of patients had discontinued opioid usage by the third postoperative day. Eighty-eight percent of patients had surplus opioid medication at the time of the final follow-up. Patients undergoing meniscal repair, smokers, and those taking preoperative opioids were significantly more likely to take ‡20 pills (p < 0.05).
Conclusions:The median number of pills taken after knee arthroscopy is 7, with the majority of patients consuming £20 pills. Meniscal repair, smoking, and preoperative opioid usage were associated with higher postoperative opioid consumption.Level of Evidence: Prognostic Level IV.

Animal fracture models have been extensively applied to preclinical research as a platform to identify and characterize normal and abnormal physiological processes and to develop specific maneuvers that alter the biology and biomechanics being examined. The choice of animal model employed in a study bears a direct relationship to the specific intervention being analyzed. The animal models employed should be described clearly, control-group data should be established, and reproducibility should be defined from experiment to experiment and from institution to institution so that quantitative and qualitative outcomes can be reliably compared and contrasted to other related studies.
Fractures of the tibial eminence are rare, accounting for less than 1% of the injuries involving the anterior cruciate ligament (ACL). Most agree that nondisplaced fractures can be managed nonoperatively, but debate exists over the ideal treatment of displaced fractures. This systematic review evaluates the outcome of nonoperatively and operatively managed displaced tibial eminence fractures. The PubMed, Embase, and Cochrane databases were queried. Inclusion criteria included reported outcomes of displaced tibial eminence fractures, minimum 2-year follow-up, and English language. Outcomes reported were pooled and included the following: clinical instability (Lachman/anterior drawer, pivot shift, and KT 1000), patient-reported pain and/or instability, return to sport, Lysholm, Tegner, and the need for ACL reconstruction. Comparison was made in the outcomes of nonoperatively and operatively treated fractures and between suture and screw fixation techniques. Overall 16 studies met the inclusion criteria. The pooled mean age was 23 years and mean follow-up was 35 months. Clinical instability was seen in 70% of nonoperatively treated patients and 14% of operatively treated patients (p < 0.0001). Patient-reported instability was higher in nonoperatively treated patients (54 vs. 1.2%, p < 0.0001), as was the rate of ACL reconstruction (10 vs. 1.0%, p = 0.036). In comparing suture fixation to screw fixation, patient-reported instability and the rate of ACL reconstruction were equivalent. Patients treated with screw fixation had a higher incidence of clinically measured instability (Lachman and KT arthrometer) and an increased rate of hardware removal (3.9 vs. 64.9%, p < 0.05). Surgically managed patients report less instability, are higher functioning, and require fewer ACL reconstructions when compared with nonoperatively treated patients. Suture fixation was associated with improvements in clinical measures of stability and decreased need for hardware removal; however, patient perception of stability and need for ACL reconstruction was no different between the two treatment methods.
The majority (71%) of active patients with hip dysplasia return to presurgical or higher activity levels after open hip preservation surgery with the periacetabular osteotomy.
We found that preoperative HGT is a safe and useful adjuvant to the treatment of patients with severe scoliosis. Significant deformity correction averaging 35% percent can be expected, with the majority of deformity correction occurring after 3 to 4 weeks. In the majority of patients, this correction is maintained or even improved with subsequent surgical correction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
