ABSTRACT

INTRODUCTION

The authors evaluate the results of endoscopic treatment and analyse the causes of persisting difficulties in retrocalcaneal bursitis unresponsive to conservative treatment. Stated as one of the causes is the possible chronic irritation of minor/partial tears of anterior parts of the distal portion of the Achilles tendon, which have no chance to heal due to continued overload and impingement syndrome of the superior prominence of the calcaneal tubercle.

MATERIAL AND METHODS

The authors evaluate the group of 24 patients (10 women and 14 men) diagnosed with retrocalcaneal bursitis, who reported more than 12 months of difficulties and in whom the conservative therapy options have already been exhausted. The decision to perform a revision arthroscopy was made by the authors based on chronic long-lasting difficulties, clinical examination, calcaneus radiograph, ultrasound examination and negative response to the performed conservative treatment. The MRI scan was obtained in 4 patients. In 11 patients during arthroscopy the Achilles tendon was intact, in 13 patients (54.2%) minor tears were detected on the anterior aspect of the distal Achilles tendon, not diagnosed preoperatively (by ultrasound examination). In all the patients, resection of the prominence of the calcaneal tubercle was performed, whereas in patients with affected Achilles tendon also the loose tendon fragments were resected.

RESULTS

A total of 23 patients reported an improvement of their condition, the pain subsided at 21-43 days. Altogether 21 patients returned to activities carried out before the onset of pain. The AOFAS score values measured preoperatively in patients with an intact tendon were 59.5 ± 15.0, in patients with an injured tendon it was 45.57 ± 9.6, while 6 months after the surgery the values were 95.7 ± 6.2, or 88.71 ± 7.8 respectively. In 1 female patient, with one prior surgery, diagnosed with a partial tear of the Achilles tendon, the effect of the surgery was unsatisfactory. After six months the patient underwent an open revision surgery and the Achilles tendon reinsertion. No intraoperative or postoperative complications were observed.

DISCUSSION

The endoscopic technique facilitates a more visible bone resection, with better control of resection, which is less invasive than the open technique, the source of irritation can be removed, which is not always only the prominence of the calcaneal tubercle, but another cause of persisting problems can also be a microtrauma affecting the anterior portion of the Achilles tendon, with a reactive hyperaemia in bursal tissue. Compared to literature and also based on the results of the authors of this retrospective study, the endoscopic calcaneoplasty is less invasive than the open surgery. It is always necessary to properly diagnose the causes of difficulties and to timely respond to persisting symptoms in patients, not responding satisfactorily to conservative therapy.

CONCLUSIONS

The findings presented by the authors provide a new perspective on the causes of chronic problems such as the "posterior heel pain" and tend to give preference to the active endoscopic approach in patients with persisting problems, not responding to conservative treatment, predisposed based on the radiological examination and with a positive finding on ultrasound or MRI scan.
