OBJECTIVE: Musculoskeletal pain (MSP) conditions are the biggest cause of disability and internationally, Indigenous peoples experience a higher burden. There are conflicting reports about Aboriginal Australians and MSP. We conducted a systematic review to describe the prevalence, associated factors, impacts, care access, health care experiences, and factors associated with MSP among Aboriginal Australians. METHODS: A systematic search of quantitative and qualitative scientific and grey literature (PROSPERO number: CRD42016038342)...

OBJECTIVE: To investigate demographic, symptom-related and cognitive determinants of cane use for knee osteoarthritis (OA) and prioritise the factors that could facilitate cane use in people with no previous cane use. METHODS: A survey of people aged ≥45 years with a clinical diagnosis of knee OA was conducted. The survey included two sections: i) demographic and cognitive determinants of cane use assessed via subscales of the Cane Cognitive Mediator Scale; ii) 19 statements, underpinned by the Behaviour Change Wheel theoretical framework, relating to factors that could facilitate regular cane use...

INTRODUCTION: Severe cases of genu varum represent a major challenge in obtaining normal configuration of the proximal tibia and overall limb alignment. PRESENTATION OF CASE: We performed inverted V-shaped high tibial osteotomy (HTO) by using a locking plate for recurrent severe bilateral tibia vara in a 15-year-old female patient with Turner syndrome. Preoperative medial proximal tibial angle (MPTA) and standing femorotibial angle (FTA) of the right/left legs were 67°/69° and 197°/203°, respectively...

CASE: The classic metaphyseal lesion, or corner fracture, is considered a strong indicator of nonaccidental trauma. In the present case, the parents brought their 8-month-old boy to a community hospital after he stopped crawling on the right leg. A knee radiograph demonstrated an isolated metaphyseal lesion, which prompted concern for child abuse. The patient was transferred to the nearest academic medical center; the pediatric radiology expert in child abuse determined that the lesion was a normal variant and not the result of abuse...

CASE: Surgical management of tibial plateau fractures can be challenging, and complications can be devastating. We report the case of a lateral tibial plateau fracture malunion with an associated intra-articular depression, which we treated with an open-book osteotomy, obviating the need for an early corrective osteotomy or knee arthroplasty. CONCLUSION: A tibial plateau fracture malunion can be reconstructed. The surgical team should give priority to salvage options, which can obviate or delay the need for and the implications of an early total knee arthroplasty, especially in a young and active patient...

CASE: A 40-year-old woman presented to the emergency department with a comminuted fracture of the patella with separation of the bone fragments. The patient underwent an open reduction and osteosynthesis using medial and lateral 2.0-mm nonlocking plates, which subsequently led to pain in the anterior and posterior aspects of the knee. CONCLUSION: In this patient, bicolumnar nonlocking plating was unable to adequately resist the tensile forces of the extensor mechanism...

CASE: A 20-year-old patient presented with an extended composite knee defect with destruction of the medial femoral condyle, including the medial collateral ligament. Treatment included using an anterolateral thigh flap for soft-tissue reconstruction, tensor fasciae latae muscle for ligament repair, and a massive allogenic bone graft of the medial femoral condyle that was revascularized with an osteocutaneous composite free flap from the contralateral femur. At 17 months postoperatively, the outcome was evaluated with scores on several established scales and radiographic assessment...

CASE: A large surgical correction was required for severe hip dysplasia, which was associated with a delayed-onset sciatic nerve injury in an adolescent patient. A cortical bone spur on the outside of the acetabular fragment produced an indirect injury that became symptomatic during mobilization of the patient. CONCLUSION: The risk of direct injury to the sciatic nerve during a periacetabular osteotomy is quite low when the osteotomy is executed in extension with abduction of the hip and flexion of the knee to reduce tension on the sciatic nerve...

CASE: A 67-year-old immunocompetent man presented with a periprosthetic infection 4 months after a left total knee arthroplasty. Repeated aspirations failed to show any organism growth. After irrigation and debridement with polyethylene exchange, there was minimal clinical improvement. Subsequently, the patient developed an arthrocutaneous fistula, which prompted a 2-stage revision arthroplasty. Mycobacterium cosmeticum grew on the culture specimens taken during this procedure, and the patient was treated with 6 months of antibiotics...

Ferdinand J Chan, Kyle Richardson, Sun Jin Kim
CASE: Three patients who underwent uncomplicated total knee arthroplasty with use of the Prineo (Ethicon) wound-closure system had development of allergic contact dermatitis. All patients were started on Keflex (cephalexin), and two were started on topical corticosteroid. In all patients, the reaction resolved within weeks. CONCLUSION: To our knowledge, the present report describes the first case series of patients in whom allergic contact dermatitis developed in association with the use of the Prineo wound-closure system during orthopaedic procedures...

CASE: A 64-year-old woman had undergone bilateral total knee arthroplasty in 1998. In 2010, she presented with a large, painless, diaphyseal soft-tissue mass of the lower leg. She indicated that she had no history of knee pain, trauma, or infection. Ultimately, the mass was found to be a synovial fluid-filled cyst that communicated with the knee joint, which was a result of severe osteolysis. CONCLUSION: Large diaphyseal tibial masses in the presence of total knee arthroplasty should raise a high index of suspicion not only for tumors and infections, but also for severe osteolysis...

CASE: An 87-year-old man fell onto a flexed knee and sustained a closed intra-articular patellar dislocation. A closed reduction was performed under intravenous sedation by flexing the knee to 90°, applying an anterior drawer force to the tibia, and applying pressure to the inferior pole of the patella. The day after reduction, weight-bearing was begun in a hinged brace set at 0° to 90°. Full function was regained by 6 weeks postreduction. CONCLUSION: Intra-articular patellar dislocation may present as an unusual cause of a locked knee...

CASE: We present a case of lower-limb trauma associated with an extensive soft-tissue defect around the knee joint, which led to the exposure of bone and the metalwork that was used for the management of the associated fractures. Coverage was performed with a distally based sartorius muscle flap in a single-stage procedure, allowing good recovery with a nice aesthetic and functional outcome at the 1-year follow-up. Additionally, we discuss alternative options for the coverage of severe soft-tissue defects based on the clinical context...

CASE: The medial collateral ligament (MCL) is the most commonly injured ligament of the knee; however, to our knowledge, avulsion fractures of the MCL resulting in an intra-articular fragment have not been reported. We present the case of a 55-year-old woman with a posterior cruciate ligament avulsion fracture and an MCL avulsion fracture with an intra-articular bony fragment. CONCLUSION: Patients who sustain trauma to the knee should be carefully evaluated for ligamentous avulsion injuries...

BACKGROUND: No well-controlled studies have compared the long-term outcome of anterior cruciate ligament (ACL) reconstruction with hamstring tendon autograft between adolescents and adults. Increased posterior tibial slopes (PTSs) have been reported in the ACL-injured versus controls, but the effect of PTS on the outcome after reconstruction is relatively unexplored. PURPOSE: To compare the prospective longitudinal outcome of "isolated" ACL ruptures treated with anatomic endoscopic ACL reconstruction using hamstring tendon autograft over 20 years in adolescent and adult cohorts and to examine factors for repeat ACL injury...

The aim of this pilot project was to introduce a novel use of acellular dermal matrix (ADM) in combination with infrapatellar fat pad mesenchymal stromal cells (IPFP-MSCs) to effect repair in a rabbit osteochondral defect model. ADM, in a range of surgical procedures, has been shown to promote remodelling of tissue at the site of implantation. Rabbit-derived ADM (rabADM) was prepared from the skin of donor rabbits. Autologous IPFP-MSCs were obtained at the time of knee surgery. Osteochondral defects (4mm cartilage outer/2mm central bone defect) were drilled into distal femoral condyles of 12 New Zealand White rabbits...

Medial unicompartmental knee arthroplasty (UKA) is an accepted treatment for isolated medial osteoarthritis. However, using an improper thickness for the tibial component may contribute to early failure of the prosthesis or disease progression in the unreplaced lateral compartment. Little is known of the effect of insert thickness on both knee kinematics and ligament forces. Therefore, a computational model of the tibiofemoral joint was used to determine how non-conforming, fixed bearing medial UKA affects tibiofemoral kinematics and tension in the medial collateral ligament (MCL) and the anterior cruciate ligament (ACL) during passive knee flexion...

Many important notions in Life Sciences are linked with the idea of cycles, periodicity, fluctuations and transitions. The aim of this paper is to use spectral analysis in a unique way to study and quantify whole body coordination during gait. A participant walked at 3 km/h and ran at 15 km/h on a treadmill for 2 minutes. Position of the approximate center of rotation of the toe, ankle, knee, hip, shoulder, elbow and wrist, heel, PSIS and head were collected (CODAmotion; 100 Hz). Fast Fourier Transform was performed on x-coordinate data of the 1) knee marker; 2) 4 markers attached to the free lower limb (toe, ankle, heel and knee); 3) left and right free lower limbs; 4) whole body (all markers)...
