We dissected 12 fresh-frozen leg specimens to
identify the insertional footprint of each fascicle of the Achilles tendon
on the calcaneum in relation to their corresponding muscles. A further
ten embalmed specimens were examined to confirm an observation on
the retrocalcaneal bursa. The superficial part of the insertion
of the Achilles tendon is represented by fascicles from the medial
head of the gastrocnemius muscle, which is inserted over the entire
width of the inferior facet of the calcaneal tuberosity. In three
specimens this insertion was in continuity with the plantar fascia
in the form of periosteum. The deep part of the insertion of the
Achilles tendon is made of fascicles from the soleus tendon, which
insert on the medial aspect of the middle facet of the calcaneal
tuberosity, while the fascicles of the lateral head of the gastrocnemius
tendon insert on the lateral aspect of the middle facet of the calcaneal
tuberosity. A bicameral retrocalcaneal bursa was present in 15 of
the 22 examined specimens. This new observation and description of the insertional footprint
of the Achilles tendon and the retrocalcaneal bursa may allow a
better understanding of the function of each muscular part of the
gastrosoleus complex. This may have clinical relevance in the treatment
of Achilles tendinopathies. Cite this article:
The purpose of this study was to evaluate the early functional outcome of this new modification of the Brostrom-Gould lateral ligament reconstruction using suture anchors and triple breasting of ATFL. AOFAS hindfoot scoring system was the primary outcome measure used. Between January 2008 and May 2011, data was collected prospectively, pre and postoperatively. Surgery for all patients included ankle arthroscopy plus whatever other minor procedure was indicated and was performed by the senior author. Postoperatively at 3 months and 12 months and in May 2011 patients were asked to attend a research clinic and their scores were obtained. Anterior drawer laxity and patient satisfaction, activity resumption and complications were some of the other information recorded. A mean follow up of 25 months on 18 ankles is presented which is amongst the longest in the literature for this procedure. Comparing pre and postoperative AOFAS scores revealed a statistically significant mean improvement of 39 points p < 0.05 with mean preoperative score being 53 and at 25 months being 89. All ankles felt clinically stable on repeated anterior drawer testing. 8 patients had resumed normal pre-injury level of activities (including sports), 8 had some reduction in normal level of activity and 2 did not carry out physical prior to operation. One patient complained of scar tenderness otherwise no complications were noted. 13 patients were extremely satisfied with results of surgery, 4 were very satisfied and 1 was moderately satisfied. The mid-term results of our modification show it to be safe, reproducible and highly successful in producing clinically and functionally stable ankles with high patient satisfaction. This includes a statistically significant improvement in AOFAS scores. This exceeds the results in the published literature.
