A Population-Level Summary of Health Care Utilization for the Management of Patellar Tendinopathy in the Military Health System
J Knee Surg DOI: 10.1055/s-0042-1751266Patellar tendinopathy (PT) is a common nontraumatic orthopaedic disorder of the knee suffered by many service members. Understanding the make-up of usual care for PT at the system level can better frame current clinical gaps and areas that need improvement. Exercise therapy is recommended as a core treatment for PT, but it is unclear how often it is used as a part of usual care for PT within the Military Health System (MHS). The purpose of the study was to identify interventions used in the management of PT and the timing of these interventions. A secondary purpose was to determine if...

Does Surgery for Concomitant Cruciate and Meniscus Injuries Increase or Decrease Subsequent Comorbidities at 2 Years?
This study aimed to compare differences in comorbidity proportions between surgical and nonsurgical approaches in Military Health System beneficiaries who had concurrent cruciate and meniscus injuries. The retrospective case control design included 36-month data that were analyzed to reflect 12 months prior to injury/surgery and 24 months after injury/surgery. A comparison of differences within and between groups in surgical and nonsurgical approaches was calculated and logistic regression was used to determine if surgery increased or decreased the odds of comorbidities at 24 months. In our sample of 2,438 individuals with...

Orthopaedic Trainee Views on Robotic Technologies in Orthopaedics: A Survey-Based Study
J Knee Surg DOI: 10.1055/s-0042-1748901The use of robotics is a growing area within the field of surgery, especially in orthopaedics. To date, there is no literature examining orthopaedic trainee perception of or comfort with robotics in orthopaedics. An assessment of the next generation's attitudes regarding this technology is necessary. An anonymous, national, web-based questionnaire containing 16 multiple-choice questions and 25 5-point Likert's scale questions was sent to 66 Accreditation Council for Graduate Medical Education (ACGME)-approved orthopaedic residency training programs. The survey was designed to discern ...

Differences in Outcomes between Patellar Dislocations Managed in Emergent versus Non-Emergent Care Settings
This study compared differences in downstream care type and intensity of services based on whether initial care occurred in emergent or non-emergent care settings. In our sample of 1,523 Military Health System (MHS) beneficiaries with patellar dislocation and 2-year follow-up, we found non-significant differences in costs, intensity of services, and rates of surgical repair regardless of whether the patient was initially seen in an emergent versus non-emergent care setting. Although we found significant increases in the use of imaging, patellar dislocation-related medical visits, and frequency of closed treatment approache...

Anterior Cruciate Ligament Reconstruction with Autologous Hamstring Single- versus Double-Bundle Graft: A Prospective Study with 10-Year Follow-up
J Knee Surg DOI: 10.1055/s-0042-1748898The purpose of the present study was to compare the clinical and subjective outcomes of anterior cruciate ligament (ACL) reconstruction using an autologous hamstring double bundle (DB) with a single bundle (SB) after a 10-year follow-up. A prospective comparative cohort study was performed of 47 consecutive patients with ACL rupture included between May 2006 and March 2008. Inclusion criteria were less than 2 years since the injury date, no previous surgery on the affected knee, and having closed growth plates. Patients were divided into two groups: (1) SB group (n = 25) and (2) D...

Can Component Size in Total Knee Arthroplasty Be Predicted Preoperatively? —An Analysis of Patient Characteristics
Conclusion A patient's shoe size demonstrates a strong correlation to the TKA implant size, and when combined with standard demographic variables the predictive reliability is further increased. Here, we present a predictive model for implant sizing based solely on easily attainable demographic variables, that will be useful for preoperative planning to improve surgical efficiency.

Comparative Results of Anterior Cruciate Ligament Reconstruction with Full Tibial Tunnel: Quadrupled Semitendinosus Suspensory Femoral and Tibial Fixation versus Quadrupled Semitendinosus and Gracilis Suspensory Femoral and Tibial Screw and Staple Fixation
This study compared the clinical outcomes of patients treated with described “modified all-inside” anterior cruciate ligament reconstruction (ACLR) technique with those of patients treated with suspensory femoral fixation and a bioabsorbable tibial interference screw with the ACLR technique. From 2017 to 2019, 98 patients who underwent ACLR surgery by two surgeons using either of the techniques were included in this study. Patients in group 1 were treated with the “modified all-inside” ACLR technique. In this technique, only the semitendinosus tendon was harvested as a four-strand graft and fixed to the tibia and f...

Comparable Outcomes Between Native and Periprosthetic Fractures of the Distal Femur
This study compares differences in hospital treatment, morbidity, and mortality associated with periprosthetic distal femur fractures at an urban level 1 trauma center. We retrospectively reviewed all adult AO/OTA type 33 fractures (526) that presented to our institution between 2009 and 2018. In total, 54 native and 54 periprosthetic fractures were matched by age and gender. We recorded demographics, operative measures, length of stay (LOS), discharge disposition, and mortality. We used McNemar's and paired t-tests for analysis where appropriate (p < 0.05) (IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY;...

Response Bias for Press Ganey Ambulatory Surgery Surveys after Knee Surgery
J Knee Surg DOI: 10.1055/s-0042-1748896The Press Ganey Ambulatory Surgery (PGAS) survey is an emerging tool used to capture patient satisfaction after elective surgery. Evaluating patient satisfaction is important; however, quality improvement (QI) surveys used to capture the patient experience may be subject to nonresponse bias. An orthopaedic registry was used to retrospectively identify patients who underwent ambulatory knee surgery from June 2015 to December 2019. Multivariable logistic regression was performed to identify independent predictors of PGAS survey nonresponse and response. In the cohort of 1,161 patients, ...

The Effect of Early versus Late Manipulation Under Anesthesia on Opioid Use, Surgical Complications, and Revision Following Total Knee Arthroplasty
J Knee Surg DOI: 10.1055/s-0042-1749607Previous studies of early versus late manipulation under anesthesia (MUA) do not report on postoperative opioid utilization or revisions and focused on small single-institution retrospective cohorts. The PearlDiver Research Program (www.pearldiverinc.com), which uses an all-inclusive insurance database, was used to identify patients undergoing primary total knee arthroplasty (TKA) who received (1) late MUA (>12 weeks), (2) early MUA (≤12 weeks), or (3) TKA only. To develop the control group cohort of TKA-only patients, 3:1 matching was conducted using 11 risk factor variables dee...

The Effect of Prosthesis Type on Intraoperative Soft-Tissue Balance and Clinical Outcomes in Modified Kinematically Aligned Cruciate-Retaining Total Knee Arthroplasty
Conclusion Joint component gaps showed no significant differences between the two groups from 0 to 30 degrees of flexion. However, during 60 to 120 degrees of flexion, joint component gaps of SR group showed significantly larger values than those of MR group (p < 0.05). There were no significant differences in varus/valgus balance throughout the range of motion between the two groups. The postoperative clinical outcomes showed no significant differences between the two groups.
Interpretation Despite no difference in clinical outcomes, joint component gap showed different patterns due to the prosthesis type ...

Conclusion This was the largest retrospective study reporting the application of SKMEP in bone sarcoma patients. For selected skeletally immature bone sarcoma patients, SKMEP is an option with satisfactory functional outcomes and survival rates.
