Background: Schatzker type-4 to 6 tibial plateau fractures most commonly occur when the distal femur is driven through the proximal tibial articular surface. This mechanism of injury can be equivalent to a knee dislocation and carries an increased risk of vascular injury. Our institution screens all Schatzker type-4 to 6 tibial plateau fractures with symmetric pulses for a vascular injury by measuring the ankle-brachial index (ABI).

- * Data from 207 patients showed that factors like body mass index (BMI) and post-operative infections significantly impacted PROM scores and likelihood of returning to work.
- * The findings suggest that post-operative infections lead to considerably poorer outcomes, highlighting the need for careful management to improve patient recovery after surgery.
Article Synopsis
- The study evaluated the impact of a blast injury on intra-compartmental pressure (ICP) in the lower leg of pigs, aiming to create a more natural model of acute compartment syndrome (ACS).
- Researchers induced a tibial fracture and simulated a blast injury, monitoring ICP and comparing injured limbs to control legs.
- Results showed that blast injuries significantly elevated ICP, with sustained high pressures observed even at 48-72 hours post-injury, despite not needing external manipulation to achieve these levels.
Article Synopsis
- * A study over 21 years found that many sustentaculum fractures were missed in initial radiographic assessments, particularly in high-energy trauma cases such as Hawkins II fractures.
- * The study concluded that while independent fixation of these fractures is common, it does not significantly impact the development of post-traumatic osteoarthritis or the need for re-operation.
Article Synopsis
- Total hip arthroplasty (THA) is often performed on patients with hip dysplasia who can't have periacetabular osteotomy, but the effects of osteoarthritis severity on their recovery post-THA are not well understood.
- A study examined the outcomes of 263 dysplasia patients undergoing THA compared to 1,225 patients with primary osteoarthritis, focusing on their recovery and patient-reported outcome measures (PROMs) over one year.
- Results showed no significant differences in PROMs or revision rates between dysplasia patients with mild and severe osteoarthritis, with all groups having similar recovery curves at various follow-up points.
Article Synopsis
- The study aimed to compare the patient-reported outcomes of individuals with hyperextension varus tibial plateau (HEVTP) fractures to those with non-HEVTP fractures at a Level 1 Trauma Center.
- Out of 207 patients analyzed, HEVTP fractures were more common in younger, predominantly male patients with a higher body mass index and were associated with greater ligamentous and vascular injuries.
- Although overall physical function scores were similar, HEVTP patients reported significantly lower scores in quality of life and other specific measures, indicating that HEVTP fractures may have more negative impacts on certain aspects of recovery.
Article Synopsis
- The study aims to establish patient-acceptable symptom state (PASS) thresholds for physical function and pain in patients who had tibial plateau fractures treated operatively, focusing on factors influencing these thresholds.
- Conducted at a Level I trauma center, the research involved 159 patients treated between 2016 and 2021, who filled out patient-reported outcome measures over at least one year.
- Results indicated that 60% were satisfied with their overall outcome; various methods calculated PASS thresholds for global outcome, pain, and function, revealing younger patients or those with specific fracture types had significantly different PASS-Pain thresholds.
Article Synopsis
- This study looked at whether fixing a certain knee injury (lateral meniscus) during surgery for another knee problem (tibial plateau fracture) made a difference in how patients felt afterward.
- It involved 207 patients over a couple of years, and about 35% of them had the meniscus injury fixed during their operation.
- The results showed that there were no big differences in recovery or how patients reported their knee function whether they had the meniscus fixed or not.
Article Synopsis
- Tibial plateau fractures in skiers are serious injuries, and there is a lack of research on patient outcomes and returning to skiing after surgery.
- The study aimed to identify factors influencing whether patients returned to skiing post-surgery and to assess changes in their skiing performance.
- Out of 90 analyzed patients, only 45.6% returned to skiing, with men and those injured while skiing being more likely to return; many experienced a significant decline in skiing ability after their injury.
Article Synopsis
- The study investigated how various patient factors affect recovery from total hip arthroplasty (THA), focusing on variables like sex, race, BMI, tobacco use, and mental health.
- A total of 1,724 patients were analyzed, with findings showing that women, obese individuals, and smokers had consistently lower recovery scores, as did black patients over the year following surgery.
- The results indicate the importance of tailoring recovery approaches and expectations based on an individual's demographic and health background, especially regarding opioid use and mental health issues.
Article Synopsis
- A large central ingrowth peg was studied as a way to reduce glenoid loosening in total shoulder arthroplasty (TSA), but issues arise when bone ingrowth doesn’t happen, leading to more complications in revisions.
- A retrospective case series analyzed 49 TSA-to-reverse TSA revisions from 2014 to 2022, comparing outcomes between patients with central ingrowth pegs and those with noningrowth components based on various metrics.
- Findings showed that patients with central ingrowth pegs had a shorter time to revision and a lower need for structural allografts compared to non-ingrowth, prompting further investigation into the causes of glenoid failure related to component design and revision timing.
Article Synopsis
- Inequalities in reimbursements between male and female orthopaedic surgeons are prevalent, with women receiving significantly lower payments despite contributing valuable services.
- The study analyzed Medicare data and included over 19,000 orthopaedic surgeons, revealing that female surgeons billed fewer codes and services compared to their male counterparts.
- The results highlighted a mean payment difference of $59,748.7 in favor of male surgeons, stressing the importance of addressing these disparities to encourage more women to enter the orthopaedic field.
Article Synopsis
- Patient-reported outcome measures (PROMs) are used to assess recovery and satisfaction in patients after total hip arthroplasty (THA), aiming to understand the trajectory of recovery over the first year.
- In a study with 1,898 patients, significant improvements were observed in PROMs post-surgery, with the best recovery noted within the first month, while physical activity improvements took longer to manifest.
- The findings suggest that patients can expect the most noticeable improvements in satisfaction metrics within one month, functional recovery by three months, and gait quality to potentially lag until after one year, which can guide patient expectations and care strategies.
Article Synopsis
- * Researchers analyzed data from 158 hips to check how factors like age, body mass index (BMI), and sex relate to the severity of cartilage and labral injuries.
- * They found that increased AP cam deformity is strongly associated with worse cartilage damage, with the odds of serious injury rising significantly with changes in the deformity's angle.
Article Synopsis
- The study evaluated how different reduction techniques impact the alignment of tibial shaft fractures after intramedullary nail (IMN) fixation in 428 adult patients at a trauma center from 2008 to 2017.
- Results showed that using traveling traction (TT), with or without percutaneous clamps (PC), significantly improved coronal alignment compared to manual reduction (MR) alone, with lower rates of malalignment.
- No significant differences were found in sagittal alignment across techniques, and there was excellent reliability in measuring alignment outcomes, particularly in the coronal plane.
Article Synopsis
- A study analyzed how the representation of women in orthopaedic surgery has evolved over time in the U.S., identifying trends in overall, regional, and subspecialty participation among active orthopaedic providers.
- Using the National Provider Identifier registry, researchers focused on a cohort of 31,296 orthopaedic surgeons, finding that only 8% were women.
- The study also projected that, based on current growth rates, women orthopaedic surgeons might not achieve gender parity with all women physicians (36.3%) for several more years.
