Background

Total Knee Replacement (TKR) is an effective treatment for knee arthritis. One long held principle of TKRs is positioning the components in alignment with the mechanical axis to restore the overall limb alignment to 180 ± 3 degrees. However, this view has been challenged recently. Given the high number of replacements performed, clarity on this integral aspect is necessary. Our objective was to investigate the association between malalignment and outcome (both PROMs and revision) following primary TKR.

Metod

A systematic review of MEDLINE, CINHAL, and EMBASE was carried out to identify studies published from 2000 onwards. The study protocol including search strategy can be found on the PROSPERO database for systematic reviews.

Background

Continuous post-operative infusion of local anaesthetic solutions has been implicated as the causative factor in many cases of chondrolysis. Recent in-vitro studies have shown that even a single exposure to local anaesthetic can cause apoptosis and mitochondrial dysfunction leading to chondrocyte death. Glucosamine has been shown to have a protective and reparative effect on articular cartilage.

Aims

To compare the effect of a single exposure of different local anaesthetic solutions on human articular cartilage and to investigate the protective and reparative effects of Glucosamine on articular cartilage exposed to 0.5% Bupivacaine.

Background

There are several case reports of chondrolysis following joint arthroscopy. Continuous post-operative infusion of local anaesthetic solutions, especially 0.5% Bupivacaine, has been implicated as the causative factor in many of these cases. Recent in vitro studies have shown that even a single exposure of articular cartilage to different local anaesthetic solutions can cause apoptosis and mitochondrial dysfunction in chondrocytes leading to cell death. There is currently no study looking at methods to prevent this toxicity of local anaesthetic solutions to articular cartilage. Glucosamine has a protective and reparative effect on articular cartilage and a Cochrane review in 2007 found that it provides mild benefit in pain and function in patients with arthritis.

Aims

Oncologic: To compare the effect of a single exposure, in vitro, of different local anaesthetic solutions on human articular cartilage.

To investigate the protective and reparative effects of Glucosamine on articular cartilage exposed to 0.5% Bupivacaine.

Background & aim

There have been many operations described for the treatment of hallux valgus deformities and b ette done separately with variable success rates. Our aim is to radiologically assess the outcome following simultaneous osteotomies to the 1st and 5th metatarsals in symptomatic patients with splay foot. To our knowledge, this procedure has not been described in the literature yet.

Materials & method

9 symptomatic patients (12 feet) were included in the study. The pre-operative and post-operative X-rays were assessed and the hallux valgus angles, 1st and 2nd intermetatarsal angles, distal metatarsal articular angles (DMAA), 4th and 5th intermetatarsal angles, maximum widths of the 1st and 5th metatarsal heads and the maximum distance between 1st and 5th metatarsals were calculated. The improvement in the angles and distances post-operatively were then assessed for statistical significance using Non-parametric paired T tests.
