Results
In both groups elongation of the repaired tendon was observed (difference between the length of the healthy and the repaired tendons measured: OS -2.07 mm,
SD 2.02 mm,
PS -2,48 mm,
SD 2,18 mm),
however,
there was no statistical significance found (p=0.181).

There was no statistically significant difference between other measurements as well: the difference between cross-sectional areas of the healthy and surgically treated tendons (OS -2,73 mm2,
SD 1,16 mm2,
PS -2,56 mm2,
SD 0,94 mm2,
p=0.603),
cross-sectional areas of the calf muscles (the medial head of gastrocnemius (p=0.631),
the lateral head of gastrocnemius (p=0.58),
soleus (p=0.701),
flexor digitorum longus (p=0.586),
flexor hallucis longus (p=0.447)) and cross-sectional areas of the whole calf (p=0.654).
Fig.7.
Comparing both groups,
there was no significant difference found in muscle degeneration (p=0.626),
mucoid degeneration (p=0.385) and intratendinous cyst formation (p=0.53).
After 24 months of follow-up statistically significant changes were observed: in both groups the cross-sectional areas of the Achilles tendons became smaller (OS p=0.004,
PS p=0.012).
Fig.8.
Enlargement of cross-sectional areas of calf muscles was also observed,
however it was not statistically significant,
for example in OS group the cross-sectional area of the lateral head of gastrocnemius became larger (p=0.101).
