High tibial osteotomy (HTO) is a common procedure for treating medial compartment knee arthritis. The main goal is to reduce knee pain by transferring weight-bearing loads to the relatively unaffected lateral compartment and thus delaying the need of total knee replacement (TKR) by slowing or stopping destruction of medial compartment.

Between 2002 and 2010, 34 HTO's were carried out in 32 patients (Mean age 44.2). Results were reviewed in 23 patients with an average follow-up of 10.2 years (range 6–14 years). Oxford knee score (OKS) assessment was carried out on those patients. Of the remaining 11 patients, one was excluded, 2 were lost to follow-up, and 2 had died. Five cases had TKR at an average 8.8 years since having HTO.

OKS results revealed nine cases (39.1percnt;) scored (40–48) which indicate satisfactory joint function and don't require treatment. Three cases (13percnt;) scored (30–39) indicating mild to moderate arthritis. Six cases (26.1percnt;), scored (20–29) indicating moderate to severe arthritis. Five cases (21.8percnt;) scored (0–19) indicating severe arthritis.

Only five patients (14.7percnt;) had TKR (6–14) years after there HTO. The majority of cases had an OKS suggesting satisfactory joint function. Even those with scores suggesting moderate to severe arthritis were able to function normally for more than 6 years.

The successful outcome of HTO can be maintained for more than 6–16 years. We conclude that HTO should be recommended for the treatment of medial compartment arthritis of the knee in young and active patients for symptomatic improvement and maintenance of activity levels.

The incidence of deep-vein thrombosis and the need for thromboprophylaxis following isolated trauma below the knee is uncertain. We have investigated this with a prospective randomised double-blind controlled trial using low molecular weight heparin with saline injection as placebo in patients aged between 18 and 75 years who had sustained an isolated fracture below the knee which required operative fixation. All patients had surgery within 48 hours of injury and were randomised to receive either the placebo or low molecular weight heparin for 14 days, after which they underwent bilateral lower limb venography, interpreted by three independent radiologists. Further follow-up was undertaken at two, six, eight and 12 weeks.

A total of 238 patients fulfilled all the inclusion criteria, with 127 in the low molecular weight heparin group and 111 in the placebo group, all of whom underwent bilateral venography. There was no statistically significant difference in the incidence of deep-vein thrombosis between those patients treated with low molecular weight heparin or the placebo (p = 0.22). The number of deep-vein thromboses in the two groups was 11 (8.7%) and 14 (12.6%), respectively. Age and the type of fracture were significantly associated with the rate of deep-vein thrombosis (p = 0.001 and p = 0.009, respectively) but gender, comorbidities and the body mass index were not.

The overall incidence of deep-vein thrombosis in this series was 11%. There was no clinical or statistical significant reduction in the incidence of deep-vein thrombosis with the use of thromboprophylaxis. However, we accept that owing to a cessation of funding, recruitment to this trial had to be ended prior to establishing the necessary sample size. Our results cannot, therefore, categorically exclude the possibility that low molecular weight heparin treatment could be beneficial. We recommend a further multicentre trial be undertaken to resolve this matter.
