Abstract
1. Functional limb usage is earlier in cases repaired with fascial strips than those where tenoplasty is effected using tendon strip or Bunnell-Mager suturing.
2. The external immobilization of the limb appears to be essential for a minimum period of six weeks where tendon strip and stainless steel wire are used in cases of delayed repair.
3. The Range of Motion of hock joint is directly proportional to the extent of adhesions around the repaired tendo Achilles.
4. An increase in ROM does not always show an improvement in functional limb usage, if the weight bearing on the affected limb in partial or absent.
5. The greater is the trauma to the tendon and surrounding tissues the greater are adhesions as revealed by fasciagraphy.
6. All the grafts are taken up by the host tendons and there is no rejection when fresh and autogenous fascia lata or tendon strip graft are used.
7. Repair in neglected cases with a combination of fascial strips between stumps and fascia lata sheet around the gapping ends provides superior performance in terms of histopathological findings of healing and clinical features.
8. Autogenously tendon strip and fascia lata cuff when used together are comparatively slow to effect union between tendon ends.
9. Where only stainless steel wire and a fascial cuff are used in unapposed tendon ends, the healing is slower than where a strip of tendon or fascial strips are interposed between tendon ends.
10. The new fibrous tissue proliferation with mature fibroblast cells growing from the fascial cuff and surrounding tissues towards tendon junction supports the earlier findings that the healing in tendons is from without inwards.
11. At four weeks, the fate of fascial strips and tendon strip is not ascertainable histopathologically or by gross examination.
12. The fascial cuff begins to separate six weeks after repair and the tubular fascial graft remains viable till six weeks.
13. Silk appears to provoke higher cellular reaction than stainless steel wire, while the latter may incite mechanical irritation in isolated cases.
