Abstract

Purpose

The purpose of this study was to examine the incapacity of work related to work load according to the classification that has been introduced by the REFA Association and the clinical outcome after open wedge HTO with autologous bone graft from the iliac crest.

Methods

A total of 32 patients who were employed and able to work at the time of the surgery as well as treated with an open wedge HTO with the LC-DCP and autologous bone wedges from the iliac crest could be included in the radiological and clinical examination (77 months, SD ± 19). Postoperative duration of the incapacity of work and subjective ratings were based on the information provided by the patients themselves. The German classification that has been established by the REFA Association was used to classify the work load. Several clinical scores were used for clinical assessment.

Results

The duration of incapacity of work (median, 87 days; range, 14–450) demonstrated a relation to work load according to REFA. The Lysholm score, the HSS score and the score according to Lequesne augmented by 19.2 ± 16.8 (p < 0.0001), 15.6 ± 13.2 (p < 0.0001) and −6.0 ± 5.1 (p < 0.0001), respectively. The Tegner score gained from median 3 (range, 1–5) to 4 (range, 1–8).

Conclusion

In this study, a relation was found between work load divided into different categories according to the classification established by the REFA Association and the duration of incapacity of work after open wedge HTO. An improvement of all clinical scores was observed. Typical neurological complications after autologous bone transplantation from the iliac crest were observed in 19 % of our patient population.
