The time at which patients should drive following total hip replacement (THR) is dependant upon recovery and the advice they are given. The Driver Vehicle and Licensing Agency (DVLA) in the United Kingdom does not publish recommendations following THR and insurance companies usually rely on medical instruction. Few studies have been performed previously and have reached different conclusions.

Brake reaction times for patients undergoing primary THR were measured pre-operatively and at four, six and eight weeks after surgery using a vehicle driving simulator at a dedicated testing centre. Patients were prospectively recruited. Ethical approval was granted. Participants included eleven males and nine females, mean age 69 years. Side of surgery, frequency of driving and type of car (automatic or manual) were documented. Patients with postoperative complications were excluded. No adverse events occurred during the study.

Statistical analysis using Friedman's test demonstrated a statistically significant difference (P=0.015) in reaction times across the four time periods. Wilcoxon test demonstrated a highly significant difference between initial and six week mean results (P=0.003), and between four and six week results (P=0.001). No significant difference was found between six and eight weeks.

Our data suggests reaction times improve until week six and significantly between week four to six. Patients making an uncomplicated recovery following primary THR may be considered safe to return to driving from week six onwards. We recommend this is clearly documented in the medical notes, and patients should check with their insurance company prior to recommencement.

Background: Patella tendonitis is a condition often found in athletes but is also found in less active patients. It usually responds to conservative management (rest, physiotherapy and anti-inflammatory drugs) but some progress to surgery. A retrospective study was done to look at the results of this surgery in our hospital.

Patients and Methods: From 2001 to 2007, nineteen knees in sixteen patients had open patella tendon decompression. Eleven patients were still involved in sporting activity. All surgery was performed by the same surgeon. The patients were brought back to a clinic for review, examination and VISA score.

Results: All but one patient had an improvement in their pain score. Of the 11 patients that played sport, eight were able to return to sport. Five of these returned to competition.

Five patients would not have the surgery again. Only two of these had still played sport. Three of these had other knee pathology found at arthroscopy.

Conclusions: The results of the surgery were satisfactory, although they were more favourable in the patients that were still involved in sporting activities. The rehabilitation time was much longer than had been expected by most patients.
