The aim of this study was to evaluate the effect of a single per operative injection of sodium hyaluronate (HA, Viscoseal¯) into the knee following arthroscopy.

This was a prospective, randomised controlled study. Knee arthroscopy patients were randomised into two groups: one receiving bupivicaine and the other sodium hyaluronate. Pre and post operative VAS scores for pain and Western Ontario and MacMaster Universities (WOMAC) scores for knee function were obtained. Forty eight patients of a single surgeon were randomised into two groups of 24. Both groups were similar as regards to age, sex, etc. Three patients withdrew from the study after randomisation. There was significant drop in pain scores for the Viscoseal¯ group compared to Bupivicaine group particularly between three-six weeks period (p< 0.05) and a significant improvement in WOMAC scores in the study group compared to control at 3 and 6 weeks (p=0.01). Viscosupplementation after arthroscopic knee surgery offers significantly improved function and pain relief over the medium term period (three-six weeks).

Closed intramedullary nailing of the tibia is a well accepted method of treating tibial fractures. There are advantages to perfoming surgery via smaller incisions. These advantages include less muscle dissection, less pain, less blood loss and quicker recovery and discharge from hospital and improved cosmesis.

We have used an existing tibial nail (Zimmer M/DN) to carry out percutaneous nailing of tibial shaft fractures using a modified surgical technique. This report describes the operative technique and our early results.

We have used this technique in 10 patients. The main difference in the technique is the use of a Steinman pin under fluoroscopy to identify the entry point. The average incision length in these patients has been 2.5cm. We have had no early or medium term complications. Length and rotation was restored in all cases. There was no increase in the surgical time or fluoroscopy time for the operation. Post-operative analgesic use was significantly less in these patients when compared with the standard technique. The average length of hospital stay has been reduced by 25% in this early cohort.

Aim: To determine effect of single post-operative injection of Sodium Hyaluronate (Viscoseal) on the pain and joint function, following arthroscopic knee surgery.

Method: Study design: A randomized, prospective, controlled, double blinded trial after ethical approval. Study procedure: Consenting patients (age group 18–60 years) undergoing arthroscopic knee surgery were randomized to either study group or control group, after the completion of their operation. Control group had 10 mls of 0.5% Bupivacaine injected in the joint after the procedure, while study group had 10 mls of Viscoseal (Sodium Hyaluronate preparation devoid of animal protein) injected in the joint. Patients were given questionnaires to assess their pain and function at various times (Preoperatively; 2 hour following surgery; Day 1, Day 7, 3 week and 6 week following surgery). Primary efficacy parameters used were Pain visual analogue scores at rest, on movement and on weight bearing. Secondary efficacy parameters used included WOMAC questionnaire, SF-12 general health questionnaire and use of rescue medication. Patients were evaluated clinically at 6 weeks by a blinded physiotherapist.

Results: 48 patients (Average age-41 years, 20 female, 28 male) undergoing knee arthroscopy were randomized (24 patients each). The hyaluronate group exhibited markedly lesser degrees of immediate post-operative pain and swelling; reduced need for analgesics, and a significantly larger drop in WOMAC scores than the bupivacaine group (p< 0.05). SF-12 scores and delayed pain VAS score improved by a comparable amount. In particular, those undergoing partial meniscectomy exhibited greater benefits with hyaluronate. No complications were recorded in either of the groups.

Conclusion: Sodium hyaluronate (Viscoseal) injections could be safely used following arthroscopic knee surgery, to facilitate patient’s recovery.

The rate of litigation following personal injury is rising at an exponential rate with no concomitant rise in the actual incidence of these injuries. It is recognised that physical injury can lead to mental health disturbance and such mental health disturbance can delay recovery following injury. No previous study has assessed the incidence of pre-existing mental health morbidity amongst personal injury claimants.

The general practitioners records of 750 consecutive personal injury claimants were examined. Mental health diagnoses prior to the index injury were noted and classified using the Diagnostic and Statistical Manual of the American Association of psychiatry. Any treatment by mental health professionals was noted.

A highly significant excess of pre-injury psychiatric morbidity was identified in the study population. There was a 40% incidence of at least one mental health diagnosis. There was a highly significant excess of depression and anxiety. 10% of the study group had received treatment from at least one mental health professional.

Pre-existing psychiatric morbidity appears to be an independent predictive factor for pursuing litigation following personal injury. In light of existing knowledge that such psychiatric morbidity often results in prolongation of physical symptoms and poor response to standard treatment regimes, it is important to recognise such patients when providing a prognosis in a medico-legal context.
