Abstract:
Plantaris tendon (PT) might induce calf or Achilles pain. In this case report, a 59-year-old woman presented with axial instability of plantaris tendon; post Achilles tendon lengthening. She beneficiated from a needle tenotomy of the PT and had a prompt symptom alleviation. The patient was fully satisfied and had a SANE score of 95% at 12 months follow up and was able to return to moderate sports activities without limitations (hiking, Nordic walking). The instability of the PT might be considered for the differential diagnosis of medial calf pain for which needle tenotomy may be considered a valuable option.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
