BACKGROUND: Athletes often are cleared to return to activities 6 months after anterior cruciate ligament (ACL) reconstruction; however, knee function measures continue to improve up to 2 years after surgery. Interventions beyond standard care may facilitate successful return to preinjury activities and improve functional outcomes. Perturbation training has been used in nonoperative ACL injury and preoperative ACL reconstruction rehabilitation, but has not been examined in postoperative ACL reconstruction rehabilitation, specifically return to sport rehabilitation...

BACKGROUND: Movement asymmetries during walking are common after anterior cruciate ligament (ACL) injury and reconstruction and may influence the early development of posttraumatic osteoarthritis. Preoperative neuromuscular training (like perturbation training, which is neuromuscular training requiring selective muscle activation in response to surface perturbations) improves gait asymmetries and functional outcomes among people who are ACL-deficient, but the effect of postoperative perturbation training on gait mechanics after ACL reconstruction is unknown...

Management of an infected total elbow replacement is a significant clinical challenge. Although preservation of the prosthesis is ideal, a 2-stage revision is often necessary. Unlike lower limb arthroplasty, antibiotic spacers are not commercially available. Monoblock cement spacers do not allow elbow movements and are therefore associated with severe stiffness and scarring, leading to poor clinical outcomes. In our paper we present a simple and novel technique for constructing an articulating antibiotic-impregnated spacer for use as an implant for a 1-stage revision of an infected elbow arthroplasty...

The goals of sarcoma management include both a cure and the functional preservation of involved tissues and adjacent critical structures with common opinions favoring immediate reconstruction. The question arises whether these goals are contradictory. This paper discusses the question based on the experience of 28 patients with different types of extremity sarcoma, with 24 surgically treated by the University of California San Diego (UCSD) orthopedic and plastic surgery team (2011-2016) and the collection of evidence from published practice guidelines, reviews, case studies, and clinical trials...

INTRODUCTION: In this study, we proposed a three-stage treatment protocol for recalcitrant distal femoral nonunion and aimed to analyze the clinical results. MATERIALS AND METHODS: We retrospective reviewed 12 consecutive patients with recalcitrant distal femoral nonunion undergoing our three-stage treatment protocol from January 2010 to December 2014 in our institute. The three-stage treatment protocol comprised debridement of the nonunion site, lengthening to eliminate leg length discrepancy, deformity correction, stabilization with a locked plate, filling of the defect with cement spacer for inducing membrane formation, and bone reconstruction using a cancellous bone autograft (Masquelet technique) or free vascularized fibular bone graft...

Background This study was designed to assess the changes of acetylcholine receptor (AChR) and creatine kinase (CK) levels, which are important biochemical markers for muscle viability in cases of long-term muscle denervation. Scientists and peripheral nerve surgeons may find these data important regarding maximal range of muscle viability applicable for timing of effective peripheral nerve reconstructive surgery. Methods The study was conducted on 48 rats (96 gastrocnemius muscles), whose right legs were denervated by removing a 10-mm segment of sciatic nerve, while their left legs remained intact...

Immunohistochemical tissue staining enhances microvasculature characteristics, including the smooth muscle in the medial layer of the vessel walls that is responsible for regulation of blood flow. The vasculature can be imaged in a comprehensive fashion using whole-slide scanning. However, since each such image potentially contains hundreds of small vessels, manual vessel delineation and quantification is not practically feasible. In this work, we present a fully automatic segmentation and vasculature quantification algorithm for whole-slide images...

BACKGROUND: Extremity sarcomas are challenging to manage. Total eradication of tumour has to be balanced with restoration of limb function to prevent mortality and morbidity. Disease-free survival with maximum limb function is the ultimate goal in these patients. MATERIALS AND METHODS: We present a series of ten cases of extremity malignancies, where limb salvage was attempted with microvascular free fibula for limb reconstruction from the period of 2008 to 2015...

OBJECTIVE: Popliteal artery entrapment syndrome (PAES) is an uncommon anatomical anomaly, frequently described in adults. The most common symptom is claudication. Acute limb ischaemia (ALI) in children is rare, but it may evolve and lead to limb loss or lifelong complications. Clinical and surgical experience of PAES in children is reported. Data from the literature are analysed in order to assess the severity of this disease and to identify the factors characterising the diagnosis and the outcome of treatment in paediatric patients...

OBJECTIVE: Peripheral venous reconstruction surgery may be necessary for appropriate oncologic resection; however, the operative approach and surgical outcomes are not well described. We report our experience with these complex reconstructions to identify best practice. METHODS: We retrospectively reviewed all adult patients who underwent peripheral vein reconstruction for tumor resection at Mayo Clinic, Rochester (2000-2015). Patients were classified into three subgroups by the location: iliac (IL), lower extremity (LE), and upper extremity (UE)...

BACKGROUND: Anterior cruciate ligament reconstruction is associated with early onset knee osteoarthritis. Running is a typical activity following this surgery, but elevated knee joint contact forces are thought to contribute to osteoarthritis degenerative processes. It is therefore clinically relevant to identify interventions to reduce contact forces during running among individuals after anterior cruciate ligament reconstruction. The primary purpose of this study was to evaluate the effect of reducing step length during running on patellofemoral and tibiofemoral joint contact forces among people with a history of anterior cruciate ligament reconstruction...

BACKGROUND: Cyclops syndrome is characterized by loss of terminal knee extension due to proliferative fibrous nodule formation in the intercondylar notch. This complication occurs in the early postoperative period after anterior cruciate ligament reconstruction (ACLR). The pathogenesis of Cyclops syndrome is not well understood. HYPOTHESIS: Persistent hamstring contracture after ACLR is associated with an increased risk of subsequent Cyclops syndrome. STUDY DESIGN: Case-control study; Level of evidence, 3...

BACKGROUND: Muscle strength of the involved limb is known to be decreased after injury. Comparison with the uninvolved limb has become standard of practice to measure progress and for calculation of limb symmetry indices (LSIs) to determine readiness to return to sport. However, some literature suggests strength changes in the uninvolved limb also are present after lower extremity injury. PURPOSE: To examine the uninvolved limb strength in a population of adolescent athletes after an anterior cruciate ligament (ACL) injury and compare strength values with those of the dominant limb in a healthy control group...

Full-thickness wounds that have rendered patients candidates for amputation may require techniques that may include a combinatorial approach above traditional standard of care. The purpose of this retrospective study was to evaluate the effectiveness of an innovative approach whereby several therapies were combined to avoid amputation. Patients with full-thickness wounds who were previously recommended for amputation and were treated with the combinatorial approach of muscle flap reconstruction and concentrated bone marrow aspirate, platelet-rich plasma, INTEGRA Wound matrix, vacuum-assisted closure, and split-thickness skin grafts were assessed retrospectively...

OBJECTIVE: To evaluate the safety and effectiveness of neglecting superficial femoral artery (SFA) recanalization for chronic lower extremity arteriosclerosis obliterans (ASO). METHODS: Thirty-six cases treated for severe stenosis or occlusion of superficial femoral artery resulted from ASO were randomly divided into 2 groups. Twenty of them were treated by endovascular reconstruction of superficial femoral artery and the other 16 cases were not treated with their superficial femoral artery, but were only treated with the accompanied iliac and/or profunda femoral artery lesion...

INTRODUCTION: There are currently no available prostheses that can be used for extremely small femurs or tibias of adult patients in countries where allograft is unavailable. CASE REPORT: We report the case of a 17-year-old girl requiring special limb salvage technique for distal femur reconstruction following resection of malignant tumor. This technique was needed because of a very narrow canal of the tibia. We split bilateral tibial cortices longitudinally with osteotomies to enlarge tibial canal enough to insert conventional endoprosthesis...

Rotationplasty is a limb-sparing surgical option in lower limb malignancies. Sciatic or tibial nerve encasement has been considered an absolute contraindication to this procedure. We report a case of an 18-month-old girl with a rhabdomyosarcoma that affected the leg and popliteal fossa, with neurovascular involvement. Knee and proximal leg intercalary resection was performed followed by reconstruction with free microvascular rotationplasty and neurorraphy from tibial division of sciatic nerve to sural and tibial nerves, and from saphenous nerve to superficial peroneal nerve...
