Both chemical and mechanical methods of prophylaxis have reduced the incidence of thromboembolic complications following total knee replacement (TKR). Only a few studies have shown that mobilization on the first post-operative day further reduces the incidence of thromboembolic phenomena. We conducted a prospective study to verify not only if early mobilization but also whether the distance mobilized on the first post-operative day after TKR reduced the incidence of thromboembolic complications. The incidence of deep venous thrombosis and pulmonary embolism were compared in 50 consecutive patients who underwent TKR from July 2006 following a change in the mobilization protocol with 50 consecutive patients who underwent TKR before the protocol was instigated. The mobilization protocol changed from strict bed rest the first post-operative day to mobilization on the first post-operative day. Mobilization was defined as sitting out of bed or walking for at least 15-30 min twice a day. The distance mobilized was accurately recorded by the physiotherapists. All patients underwent duplex scans of both lower limbs on the fourth post-operative day. There was a significant reduction in the incidence of thromboembolic complications in the mobilization group (seven in total) compared with the control group (16 in total) (P= 0.03). Furthermore, in the mobilization group the odds of developing a thromboemobloic complication was significantly reduced the greater the distance the patient mobilized (Chi-squared linear trend = 8.009, P= 0.0047). Early mobilization in the first 24 h after TKR is a cheap and effective way to reduce the incidence of post-operative deep venous thrombosis.

A 14-year-old girl presented with a painful right foot. She was an elite water-polo player and could recall no history of specific trauma to the foot. On close and persistent questioning, she admitted to having taken up playing the drums recently, with practice sessions of up to 4 h/d. She used the foot drum with her right foot and had noticed that this was becoming increasingly painful and prevented her playing the instrument for the last 2 days. Plain films of the foot were originally reported as normal, but revised to abnormal after the scintigraphic study. Bone scintigraphy confirmed a stress fracture of the right 3rd metatarsal bone. Stress fractures of the 3rd metatarsal bone are rare with only 2 previous reports in the literature.

Australia is facing a growing burden of knee and hip osteoarthritis (OA). To address this demand in northern New South Wales, a community health-based conservative OA joint management service was established in the Tweed Valley. This paper describes the design, implementation and initial evaluation of the service. Following the principles of clinical redesign, a diagnostic phase involving consultation with key stakeholders revealed several issues. OA patients could wait up to 9 months for review by orthopaedic specialist following GP referral and received limited information on how to conservatively manage their conditions. GPs were constrained by short consultations and had limited knowledge of the latest recommendations for the conservative treatment of OA. GPs also highlighted the limitations of outdated fax systems for communication, noting their preference for secure electronic messaging. Based on these findings, the Tweed Knee and Hip Arthritis Service was established. For patients not on a waiting list for surgery, the service provides evidence-based conservative management for knee or hip OA involving standardised assessment, education, exercise, self-management strategies and regular review. An analysis of a foundational cohort of patients demonstrated improvements in a suite of validated and standardised measures for pain and function, with improvements seen as early as 1 month and sustained for 6 months. The study findings support the introduction of integrated conservative OA management models of care directly available to primary healthcare providers.
