Abstract:
Patellar tendon rupture is an uncommon but serious
complication that results in loss of knee extension during and
after total knee arthroplasty (TKA), significantly impacting
the patient’s quality of life. Various surgical treatments,
ranging from initial repair to reconstruction, are available
and accessible. In recent years, the peroneus longus tendon
autograft has been utilised to restore the knee extensor
system. The purpose of this case report was to present the
case of a patient who had a traumatic patellar tendon rupture
following TKA and requiring surgery along with peroneus
tendon augmentation. A 71-year-old woman underwent
bilateral robotic-assisted cruciate retaining TKA for a Grade
IV arthritic knee. Post surgery, on day five patient had a
history of a fall at home, following which she was unable to
extend her knees. On evaluation through ultrasonography
and radiographs, she was found to have a ruptured patellar
tendon and sprain of the medial collateral ligament. Primary
repair of the tendon along with augmentation with the
peroneus tendon was performed, and the patient was
followed for 12 months, at the end of which, the patient was
able to achieve a good functional outcome. In conclusion,
early results from patellar tendon reconstruction using an
ipsilateral peroneus longus tendon autograft following TKA
suggest that this technique is effective for managing acute
post-traumatic patellar tendon rupture. It facilitates early
recovery, yields favourable outcomes, and may reduce the
risk of infection.
