Two-Stage Revision Anterior Cruciate Ligament Reconstruction
Erickson, Brandon J; Cvetanovich, Gregory; Waliullah, Khalid; Khair, Michael; Smith, Patrick; Bach, Bernard; Sherman, Seth
The number of primary anterior cruciate ligament (ACL) tears is rapidly increasing. In patients who wish to return to their preoperative level of function, specifically as it pertains to participation in sports, the gold standard of treatment following an ACL tear remains an anterior cruciate ligament (ACL) reconstruction. Despite a majority of good/excellent results following primary ACL reconstruction, there is a growing subset of patients with persistent or recurrent functional instability who require revision ACL reconstruction. Preoperative planning for revision ACL reconstruction requires a careful understanding of the root cause of ACL failure, including possible technical causes of primary ACL failure and the presence of combined knee pathology that was not addressed at the index ACL reconstruction. The decision to perform 2-stage revision ACL reconstruction is multifactorial and is reached by technical considerations that may make a 1-stage revision less optimal, including tunnel widening, arthrofibrosis, active infection, and others. Concomitant knee pathology such as meniscal deficiency, malalignment (including an increase in posterior tibial slope), chondral lesions, and other ligamentous laxity may also require a staged approach to treatment. This evidence-based review covers the indications for 2-stage revision ACL reconstruction, surgical techniques, evidence for and technique of bone grafting prior ACL tunnels, and outcomes of 2-stage revision stratified by initial cause of ACL reconstruction failure. With proper preoperative planning and an understanding of the cause of failure following the primary ACL reconstruction, revision ACL reconstruction can offer excellent outcomes in the motivated patient.

Multimodal Imaging and Clinicopathologic Correlation in Primary Uveal Lymphoma [Case Report]
Erickson, Brandon; Mantopoulos, Dimosthenis; Schoenfield, Lynn; Cebulla, Colleen M
PURPOSE/OBJECTIVE:We report a rare case of primary uveal lymphoma and characterize it using histopathology and multimodal imaging. PATIENT AND METHODS/METHODS:A 41-year-old male presented with a 2-year history of increasingly blurry vision in his right eye and no systemic symptoms. Examination revealed a retinal detachment and mass lesion in the right eye. Radiologic and histologic testing was performed. RESULTS:Multimodal imaging localized the lesion to the choroid, and fine needle aspiration biopsy diagnosed the lesion as a low-grade B-cell lymphoma. The patient was treated with external beam radiation, resulting in regression of the mass and resolution of the retinal detachment. CONCLUSIONS:Primary uveal lymphoma is a rare, usually indolent tumor that carries a good prognosis. In this case, we show that primary uveal lymphoma has distinct findings via histopathology and multimodal imaging, and that imaging after radiation treatment documents disease regression.

Nonligamentous Soft Tissue Pathology About the Knee: A Review
Erickson, Brandon J; Campbell, Kevin; Cvetanovich, Gregory L; Harris, Joshua D; Bach, Bernard R; Sherman, Seth L
Knee pain is one of the most frequent complaints evaluated by orthopedic surgeons. It encompasses a broad range of pathology and can present in a variety of ways. Most of this pain can be attributed to essential structures of the knee, including the menisci, cruciate or collateral ligaments, and articular cartilage. However, there are underrecognized structures in and around the knee that can frequently be a cause of knee pathology and pain. Knee pain stemming from these structures may be missed or incorrectly diagnosed, and these patients often present for second and third opinions because of failure to diagnose and treat the underlying pathology. The synovial plica, suprapatellar pouch, lateral retinaculum, infrapatellar fat pad, and infrapatellar branch of the saphenous nerve are less common but still significant causes of knee pain. Although initial treatment involves various nonoperative modalities, operative treatment is often warranted. Operative and nonoperative management of these soft tissue structures may occur in isolation or with concomitant procedures, including knee ligament reconstruction, total knee arthroplasty, tibial tuberosity osteotomy, or lysis of adhesions. With proper recognition of the role of these structures in knee pain, the orthopedic surgeon can offer a valuable primary or adjunctive treatment option for patients with knee pain, especially those without localizing signs of meniscal, ligamentous, or cartilage damage.

Perineal Post Padding Technique to Improve Hip Distraction in Tall Patients
Kuhns, Benjamin D; Erickson, Brandon J; Bressler, Leah R; Sarmast, Sara M; Nho, Shane J
Hip distraction is necessary for safe arthroscopic entry into the hip joint. Achieving sufficient distraction is difficult in exceedingly tall patients (>190.5 cm) because of size limitations of currently available hip distraction systems. Inadequate distraction can delay the surgical procedure and potentially lead to complications. By repurposing a foam head-positioning block, we report a safe and inexpensive positioning technique for extending the traction distance for tall patients by 2 inches.

Orthopedic Practice Patterns Relating to Anterior Cruciate Ligament Reconstruction in Elite Athletes
Erickson, Brandon J; Harris, Joshua D; Fillingham, Yale A; Cvetanovich, Gregory L; Bush-Joseph, Charles; Cole, Brian J; Bach, Bernard R; Verma, Nikhil N
We conducted an online survey of National Hockey League (NHL), Major League Soccer (MLS), and US Olympic/World Cup Ski/Snowboard (Olympic) team orthopedic surgeons to determine practice patterns relating to anterior cruciate ligament (ACL) reconstruction in elite athletes. Of the 94 team orthopedic surgeons surveyed, 47 (50%) responded. Mean (SD) experience as a team physician was 7.73 (5.33) years for NHL, 6.77 (6.64) years for MLS, and 1.14 (0.36) years for Olympic. Mean (SD) number of ACL reconstructions performed in 2012 was 101 (51) for NHL, 78 (38) for MLS, and 110 (105) for Olympic. Overall, 33 surgeons (70.2%) indicated they would use bone-patellar tendon-bone (BPTB) autograft to treat their starting athletes. Twenty-one (44.7%) drilled the femoral tunnel through a transtibial portal, 36.2% through an anteromedial portal, and 12.8% by a 2-incision technique. All the surgeons used a single-bundle technique. Thirty-three (70.2%) did not recommend a brace for their elite athletes during play on return to sport (RTS). Twenty-seven NHL and MLS surgeons (81.8%) recommended RTS only after an athlete has passed a series of RTS tests (eg, Vail, single-leg hop). Most of the NHL, MLS, and Olympic team orthopedic surgeons who were surveyed perform their ACL reconstructions using BPTB autograft, using a single-bundle technique, and through a transtibial portal, and do not require bracing for their athletes returning to sport. Most required their athletes to complete a series of RTS tests before resuming competitive play.

Does physical therapy prevent post-operative delay in return of function following tension-band plating?
Fillingham, Yale A; Luthringer, Tyler; Erickson, Brandon J; Kogan, Monica
PURPOSE/OBJECTIVE:The clinical outcomes and complications of tension-band plating have been well documented, and commonly include a post-operative delay in return of function. We performed a retrospective comparison study to evaluate the capacity of immediate post-operative physical therapy to prevent this post-operative delay in return of function. METHODS:Sixty-seven consecutive growth-deformity patients who were treated with tension-band plating at a single institution fulfilled the study criteria. Patients were allocated into two treatment groups: no post-operative physical therapy and immediately post-operative physical therapy. All patients were evaluated for delayed return of function, which was defined as use of crutches, lack of >90° flexion and full extension of the knee, or persistent pain requiring medication at the initial 2-week follow-up visit. Rates of delayed function were compared between the two treatment groups. RESULTS:Among the study participants, 48 patients had no physical therapy and 19 patients had immediate post-operative physical therapy. Eighteen patients in the no physical therapy group reported a delay (37.5 %) while only 2 patients in the physical therapy treatment group reported a delay (10.5 %); p = 0.0386. CONCLUSIONS:Delayed return of function dramatically affects pediatric patients, causing unnecessary absence from school and strain on the caregiver. Therefore, it is important to identify treatment modalities to help mitigate the complications of surgery. We conclude that the use of immediate post-operative physical therapy statistically significantly helps patients to return more rapidly to their functional level.

The Meniscus-Deficient Knee: Biomechanics, Evaluation, and Treatment Options
Rao, Allison J; Erickson, Brandon J; Cvetanovich, Gregory L; Yanke, Adam B; Bach, Bernard R; Cole, Brian J
Meniscal tears are the most common knee injury, and partial meniscectomies are the most common orthopaedic surgical procedure. The injured meniscus has an impaired ability to distribute load and resist tibial translation. Partial or complete loss of the meniscus promotes early development of chondromalacia and osteoarthritis. The primary goal of treatment for meniscus-deficient knees is to provide symptomatic relief, ideally to delay advanced joint space narrowing, and ultimately, joint replacement. Surgical treatments, including meniscal allograft transplantation (MAT), high tibial osteotomy (HTO), and distal femoral osteotomy (DFO), are options that attempt to decrease the loads on the articular cartilage of the meniscus-deficient compartment by replacing meniscal tissue or altering joint alignment. Clinical and biomechanical studies have reported promising outcomes for MAT, HTO, and DFO in the postmeniscectomized knee. These procedures can be performed alone or in conjunction with ligament reconstruction or chondral procedures (reparative, restorative, or reconstructive) to optimize stability and longevity of the knee. Complications can include fracture, nonunion, patella baja, compartment syndrome, infection, and deep venous thrombosis. MAT, HTO, and DFO are effective options for young patients suffering from pain and functional limitations secondary to meniscal deficiency.

Do Complication Rates Differ by Gender After Metal-on-metal Hip Resurfacing Arthroplasty? A Systematic Review
Haughom, Bryan D; Erickson, Brandon J; Hellman, Michael D; Jacobs, Joshua J
BACKGROUND:Although metal-on-metal (MoM) bearing surfaces provide low rates of volumetric wear and increased stability, evidence suggests that certain MoM hip arthroplasties have high rates of complication and failure. Some evidence indicates that women have higher rates of failure compared with men; however, the orthopaedic literature as a whole has poorly reported such complications stratified by gender. QUESTIONS/PURPOSES/OBJECTIVE:This systematic review aimed to: (1) compare the rate of adverse local tissue reaction (ALTR); (2) dislocation; (3) aseptic loosening; and (4) revision between men and women undergoing primary MoM hip resurfacing arthroplasty (HRA). METHODS:Systematic MEDLINE and EMBASE searches identified all level I to III articles published in peer-reviewed journals, reporting on the outcomes of interest, for MoM HRA. Articles were limited to those with 2-year followup that reported outcomes by gender. Ten articles met inclusion criteria. Study quality was evaluated using the Modified Coleman Methodology Score; the overall quality was poor. Heterogeneity and bias were analyzed using a Mantel-Haenszel statistical method. RESULTS:Women demonstrated an increased odds of developing ALTR (odds ratio [OR], 5.70 [2.71-11.98]; p<0.001), dislocation (OR, 3.04 [1.2-7.5], p=0.02), aseptic loosening (OR, 3.18 [2.21-4.58], p<0.001), and revision (OR, 2.50 [2.25-2.78], p<0.001) after primary MoM HRA. CONCLUSIONS:A systematic review of the currently available literature reveals a higher rate of complications (ALTR, dislocation, aseptic loosening, and revision) after MoM HRA in women compared with men. Although femoral head size has been frequently implicated as a prime factor in the higher rate of complication in women, further research is necessary to specifically probe this relationship. Retrospective studies of data available (eg, registry data) should be undertaken, and moving forward studies should report outcomes by gender (particularly complications). LEVEL OF EVIDENCE/METHODS:Level III, therapeutic study.

In-hospital Mortality Risk for Femoral Neck Fractures Among Patients Receiving Medicare
Erickson, Brandon J; Nwachukwu, Benedict U; Kiriakopoulos, Emmanouil; Frank, Rachel M; Levine, Brett; Villarroel, Leonardo; McCormick, Frank M
Increased risk of mortality with time has been established in association with femoral neck fractures. However, little is known about the in-hospital mortality risk associated with femoral neck fractures in the US population. This study was conducted to determine the in-hospital mortality rate associated with femoral neck fractures and to identify independent demographic features associated with an increased risk of this primary outcome. The authors queried the PearlDiver database (PearlDiver Technologies, Inc, West Conshohocken, Pennsylvania) of Medicare patients from 2005 to 2010 for International Classification of Diseases, 9th Revision (ICD-9), diagnostic codes for femoral neck fractures and related conditions. Stratified sampling was conducted by creating a group within the data set that included patients with a death discharge using ICD-9-D-820.0 through ICD-9-D-820.13. Age, sex, and year of injury were analyzed as specific demographic variables related to mortality. A total of 751,232 femoral neck fractures occurred during the index study period. There were 11,420 deaths during the initial hospital stay, for an overall mortality rate of 1.52%. The mortality rate in patients older than 84 years was 2.06%. Of all deaths, 89% occurred in patients who were 75 years and older. The mortality rate for femoral neck fractures was 1.22% in women and 2.32% in men (odds ratio, 0.5; 95% confidence interval, 0.25-1.04). The overall mortality rate for patients in the Medicare population who were treated at an inpatient center for femoral neck fractures from 2005 to 2010 was 1.5%. Men had a mortality rate almost twice that of women. Patients older than 84 years were the most likely to die soon after sustaining a femoral neck fracture.
