In a prospective randomized control trial comparing computer-assisted vs conventional total knee arthroplasty, we previously reported that patients with coronal alignment within 3° of neutral had superior international knee society and Short-Form 12 (SF-12) physical scores at 6 weeks, 3 months, 6 months, and 12 months after surgery. Computer-assisted total(More)
A presacral mass can present a diagnostic dilemma for the surgical oncologist. Differential diagnoses include congenital causes such as teratoma or chordoma, neurological causes such as neurilemoma or neurofibroma or other malignancies such as lymphoma or sarcoma. Diagnosis usually requires imaging such as CT and MRI and tissue biopsy. We present an unusual(More)
BACKGROUND The mechanical alignment of the knee is an important factor in planning for, and subsequently assessing the success of a knee replacement. It is most commonly measured using a long-leg anteroposterior radiograph (LLR) encompassing the hip, knee and ankle. Other modalities of measuring alignment include computer tomography (CT) and intra-operative(More)
BACKGROUND Infection after primary knee arthroplasty is devastating. The aim of this study was to determine the significance of sentinel infective events prior to the development of haematogenous prosthetic knee infection. METHODS A retrospective single-centre case control study of 1641 primary knee arthroplasties was conducted between 1998 and 2006.(More)
The Charcot knee - or neuropathic arthropathy - presents a considerable challenge to the orthopaedic surgeon. Caused by a combination of sensory, motor and autonomic neuropathy, it was originally described as an arthritic sequelae of neurosyphilis. In today's western orthopaedics it is more often caused by diabetes. A Charcot knee is often symptomatically(More)
A total knee arthroplasty can be completed using two techniques; measured resection or gap balancing. A prospective blinded randomized controlled trial was completed with 103 patients randomized to measured resection (n = 52) or gap balancing (n = 51). Primary outcome measure was femoral component rotation. Secondary outcome measures were joint-line change,(More)
Ligament balancing affects many of the postoperative criteria for a successful knee replacement. A balanced knee contributes to improved alignment and stability. Ligament balancing helps reduce wear and loosening of the joint. A patient with a balanced knee is more likely to have increased range of motion and proprioception, and decreased pain. All these(More)
Three-dimensional (3D) printing is a rapidly evolving technology with the potential for significant contributions to surgical practice. There are many current applications for 3D printing technology with future applications being explored. This technology has applications in preoperative planning, education, custom manufacturing (implants, prosthetics and(More)
A 21-year-old man presented with a pathologic fracture through the posterior aspect of the calcaneus into an aneurysmal bone cyst. The patient was treated using curettage, phenol, alcohol, and burr with open reduction and internal fixation. This is the first reported case of a pathologic fracture of an aneurysmal bone cyst of the calcaneus, highlighting the(More)
Recently, researchers have been paying more attention to the dart-throwers' motion since this oblique motion is intrinsic to humans; and it leads to distinct advantages in early human evolutionary development. Despite the pivotal role of this motion, it has received relatively few formal investigations in regards to real-time data measurement due to the(More)
