Increased incidence of venous thromboembolism following hip or knee arthroplasty in winter.
Abstract BACKGROUND: Deep vein thrombosis (DVT) and pulmonary embolism (PE) cause significant morbidity and mortality following arthroplasty. A seasonal variation in the rate of PE in arthroplasty patients in the northern hemisphere has been reported. We hypothesized that there would be a similar seasonal variation in arthroplasty patients in Australia. METHODS: We performed a retrospective review of all patients who received primary and/or revision arthroplasty of the hip or knee over a 15-year period (2000-2015) across Western Australia. We identified all patients who were diagnosed with DVT and/or PE accor...

Ipsilateral femoral neck and intertrochanteric fractures with posterior dislocation of the hip: A report of two cases.
Abstract Traumatic hip dislocation usually occurs in young patients, with the increasing number of high-energy injuries, and 62-93% of reported adult traumatic hip dislocations were caused by high-speed motor vehicle crashes. However, ipsilateral femoral neck fractures and intertrochanteric fractures with posterior dislocation of the hip are extremely rare, and this injury poses a challenge to orthopaedic surgeons. Here, we report two cases of simultaneous ipsilateral femoral neck fracture, intertrochanteric fracture and posterior dislocation of the hip joint in young patients who were treated with proximal femora...

Surgical results in older patients with lumbar spinal stenosis according to gait speed in relation to the diagnosis for sarcopenia.
CONCLUSION: Postoperative gait speed was significantly improved, whereas muscle mass did not increase in the patients in this study. Therefore, low gait speed in patients with LSS seems to be derived from a neurologic disorder. The surgical results in low muscle mass patients without low gait speed were similar to those with low gait speed. Sarcopenia in elderly patients with locomotor disease should be evaluated using muscle mass alone without assessing physical performance.

Adult Morquio syndrome requiring occipito-thoracic fusion.
Abstract Morquio syndrome is a relatively rare entity that is often associated with atlantoaxial instability from early childhood due to odontoid dysplasia based on a mucopolysaccharoidal disorder. Here, we present the case of a 55-year-old male patient with Morquio syndrome who developed cervical myelopathy, which is an extremely rare condition in the older population. Myelopathy developed gradually with upper-limb paresthesia and clumsiness of both hands. The patient had a characteristic "gargoyle-like" coarse face with a trunk shortening-type short stature. Imaging of the cervical spine demonstrated s...

Pain and load progression following an early maximal strength training program in total hip- and knee arthroplasty patients.
Abstract PURPOSE: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients significantly increase muscle strength after maximal strength training (MST) initiated soon after surgery. Owing to severe postoperative pain, knee patients are anticipated to be more limited in performing heavy load exercises than hip patients. The aim of the present study was to describe pain and load progression during early MST in THA and TKA patients. METHODS: Explorative study based on secondary analyses from two randomized controlled trials: 26 THA and 16 TKA patients had their training sessions logged. They train...

Arthroscopic procedures could delay the need for a subsequent knee arthroplasty in older patients with end-stage osteoarthritis.
CONCLUSION: Arthroscopic procedures could possibly delay the need for subsequent knee arthroplasty for approximately 65 months in older patients with osteoarthritis. However, microfracture does not affect the duration between therapeutic arthroscopy and subsequent arthroplasty. Our long-term retrospective study provides an additional step in the understanding of the impact of arthroscopic procedures and a prospective case-control study would be an ideal follow-up to fully justify the application of arthroscopic procedures to delay knee arthroplasty.

Effect of leg dominance on early functional outcomes and return to sports after anterior cruciate ligament reconstruction.
CONCLUSIONS: Results from this study suggest that despite theoretical differences, leg dominance does not have a significant impact on short-term functional outcomes and return to sports. Objective measurements suggest that limb strength recovers at a comparable rate. Injuries to either leg demonstrate equally positive improvement post-ACL reconstruction given the same post-operative rehabilitation. LEVEL OF EVIDENCE: III, retrospective comparative study. LEVEL OF EVIDENCE: III, retrospective cohort study. PMID: 32067570 [PubMed - in process] (Source: Journal of Orthopaedic Surgery)

Advantages of the experience of navigation when starting manual total knee arthroplasty.
CONCLUSION: In starters of manual TKR, previous experience of performing navigated TKR may help the error values during femoral and tibial bone cutting to fall within the values similar to the median error value of navigated TKR. It may also help to reduce the operative time of manual TKR similar to the operative time of and experienced surgeon with over 100 cases of navigated TKR.
