When Can I Drive After Orthopaedic Surgery? A Systematic Review

Kevin J. DiSilvestro BA, Adam J. Santoro BS, Fotios P. Tjoumakaris MD, Eric A. Levicoff MD, Kevin B. Freedman MD, MSCE

Patients often ask their doctors when they can safely return to driving after orthopaedic injuries and procedures, but the data regarding this topic are diverse and sometimes conflicting. Some studies provide observer-reported outcome measures, such as brake response time or simulators, to estimate when patients can safely resume driving after surgery, and patient survey data describing when patients report a return to driving, but they do not all agree. We performed a systematic review and quality appraisal for available data regarding when patients are safe to resume driving after common orthopaedic surgeries and injuries affecting the ability to drive.

What are the Functional Results, Complications, and Outcomes of Using a Custom Unipolar Wrist Hemiarthroplasty for Treatment of Grade III Giant Cell Tumors of the Distal Radius?

Baichuan Wang MD, PhD, Qiang Wu MD, PhD, Jianxiang Liu MD, PhD, Songfeng Chen PhD, Zhicai Zhang MD, PhD, Zengwu Shao MD, PhD

A giant cell tumor (GCT) of bone presenting in the distal radius is rare, however, when they occur, Campanacci Grade III tumors can present formidable reconstructive challenges. They are associated with a high local recurrence rate with intralesional treatment, therefore approaches to reconstruct the wrist after en bloc resection warrant study.

Novel Augmentation Technique for Patellar Tendon Repair Improves Strength and Decreases Gap Formation: A Cadaveric Study

James C. Black MD, William M. Ricci MD, Michael J. Gardner MD, Christopher M. McAndrew MD, MSc, Avinesh Agarwalla BS, Robert D. Wojahn MD, Orchid Abar, Simon Y. Tang PhD

Patellar tendon ruptures commonly are repaired using transosseous patellar drill tunnels with modified-Krackow sutures in the patellar tendon. This simple suture technique has been associated with failure rates and poor clinical outcomes in a modest proportion of patients. Failure of this repair technique can result from gap formation during loading or a single catastrophic event. Several augmentation techniques have been described to improve the integrity of the repair, but standardized biomechanical evaluation of repair strength among different techniques is lacking.

What Are the Risk Factors for Dislocation of Hip Bipolar Hemiarthroplasty Through the Anterolateral Approach? A Nested Case-control Study

Lianhua Li MD, Jixin Ren MD, Jia Liu MD, Hao Wang MD, Qinghua Sang MD, Zhi Liu MD, Tiansheng Sun MD

Hip dislocation after treatment of a femoral neck fracture with a hemiarthroplasty remains an important problem in the treatment of hip fractures, but the associations between patient factors and surgical factors, and how these factors contribute to dislocation in patients who have undergone bipolar hemiarthroplasty through an anterolateral approach for femoral neck fracture currently are only poorly characterized.

Head-Neck Osteoplasty has Minor Effect on the Strength of an Ovine Cam-FAI Model: In Vitro and Finite Element Analyses

Ghislain Maquer PhD, Alexander Bürki MSc, Katja Nuss DVM, Philippe K. Zysset PhD, Moritz Tannast MD

Osteochondroplasty of the head-neck region is performed on patients with cam femoroacetabular impingement (FAI) without fully understanding its repercussion on the integrity of the femur. Cam-type FAI can be surgically and reproducibly induced in the ovine femur, which makes it suitable for studying corrective surgery in a consistent way. Finite element models built on quantitative CT (QCT) are computer tools that can be used to predict femoral strength and evaluate the mechanical effect of surgical correction.

Estimating the Societal Benefits of THA After Accounting for Work Status and Productivity: A Markov Model Approach

Lane Koenig PhD, Qian Zhang PhD, Matthew S. Austin MD, Berna Demiralp PhD, Thomas K. Fehring MD, Chaoling Feng PhD, Richard C. Mather MD, Jennifer T. Nguyen MPP, Asha Saavoss BA, Bryan D. Springer MD, Adolph J. Yates MD

Demand for total hip arthroplasty (THA) is high and expected to continue to grow during the next decade. Although much of this growth includes working-aged patients, cost-effectiveness studies on THA have not fully incorporated the productivity effects from surgery.

What is the Prevalence of Radiographic Hip Findings Associated With Femoroacetabular Impingement in Asymptomatic Asian Volunteers?

Taesoo Ahn MD, Chul-Ho Kim MD, Tae Hyung Kim MD, Jae Suk Chang MD, PhD, Mi Yeon Jeong RN, Kekatpure Aditya DNB, Pil Whan Yoon MD, PhD

Morphologic features of the proximal femur reminiscent of those seen in patients with femoroacetabular impingement (FAI) have been reported among asymptomatic individuals in Western populations, but whether this is the case in Asian populations is unknown.

Is Hepatitis C Infection Associated With a Higher Risk of Complications After Total Shoulder Arthroplasty?

Jourdan M. Cancienne MD, Ian J. Dempsey MD, MBA, Russell E. Holzgrefe MD, Stephen F. Brockmeier MD, Brian C. Werner MD

Despite recent advances in the treatment of hepatitis C, it is estimated that nearly 4 million Americans have a chronic form of the disease. Although research in lower-extremity arthroplasty suggests patients with hepatitis C are at risk for increased complications, including postoperative bleeding, acute postoperative infection, and general medical complications, no similar studies have investigated this question in patients undergoing total shoulder arthroplasty (TSA).

What Change in American Shoulder and Elbow Surgeons Score Represents a Clinically Important Change After Shoulder Arthroplasty?

Brian C. Werner MD, Brenda Chang MS, MPH, Joseph T. Nguyen MPH, David M. Dines MD, Lawrence V. Gulotta MD

The American Shoulder and Elbow Surgeons (ASES) questionnaire was developed to provide a standardized method for evaluating shoulder function. Previous studies have determined the clinical responsiveness of this outcome measure for heterogenous populations or patients with nonoperatively treated rotator cuff disease. Currently, to our knowledge, no studies exist that establish the clinically relevant change in the ASES score after shoulder arthroplasty.

What Factors are Associated With Clinically Important Improvement After Shoulder Hemiarthroplasty for Cuff Tear Arthropathy?

Jeremy S. Somerson MD, Patrick Sander MD, Kamal Bohsali MD, Ryan Tibbetts MD, Charles A. Rockwood MD, Michael A. Wirth MD

In selected patients with a desire to maintain activity levels greater than those recommended after reverse total shoulder arthroplasty, hemiarthroplasty remains an option for treatment of cuff tear arthropathy (CTA). However, given the relatively small case series that have been reported to date, little is known regarding which patients will show functional improvement after this surgery.

Stretching After Heat But Not After Cold Decreases Contractures After Spinal Cord Injury in Rats

Hiroyuki Iwasawa MSc, Masato Nomura MSc, Naoyoshi Sakitani MSc, Kosuke Watanabe MSc, Daichi Watanabe MSc, Hideki Moriyama PhD

Contractures are a prevalent and potentially severe complication in patients with neurologic disorders. Although heat, cold, and stretching are commonly used for treatment of contractures and/or spasticity (the cause of many contractures), the sequential effects of these modalities remain unclear.

Is Botulinum Toxin Type A a Valuable Adjunct During Femoral Lengthening? A Randomized Trial

Hoon Park MD, Soowan Shin BS, Han Sol Shin MD, Hyun Woo Kim MD, Dong Wook Kim MD, Dong Hoon Lee MD, PhD

Reduced joint ROM and distraction-induced pain are common complaints of patients who have undergone gradual femoral lengthening. Attempts to reduce the effects of lengthening on joint motion have included the use of botulinum toxin to reduce the muscle forces that restrict motion. The benefits of this approach during femoral lengthening, however, have not been conclusively established.

Are Bundled Payments a Viable Reimbursement Model for Revision Total Joint Arthroplasty?

P. Maxwell Courtney MD, Blair S. Ashley MD, Eric L. Hume MD, Atul F. Kamath MD

Alternative payment models, such as the Centers for Medicare & Medicaid Services (CMS) Bundled Payment for Care Improvement (BPCI) initiative, aim to decrease overall costs for hip and knee arthroplasties.
