This study details a successful surgical repair of a rectus femoris tear using an Achilles tendon allograft in a 48-year-old male. This technique offers a viable option for rectus femoris rupture repair.

Area of Science:

Orthopedic Surgery
Musculoskeletal Repair

Background:

Subacute and chronic rectus femoris ruptures have limited documented repair options.
Surgical intervention is often necessary for significant rectus femoris tears.

Observation:

A 48-year-old male presented with a subacute tear of the left rectus femoris muscle.
The tear was surgically repaired using an Achilles tendon allograft.

Findings:

The allograft was secured distally to the patella with suture anchors and a Krackow technique.
Proximal fixation involved multiple sutures connecting the allograft to the remaining rectus femoris tendon.
The patient achieved excellent recovery, with near-normal knee flexion and a successful straight leg raise without extensor lag.

Implications:

Achilles tendon allograft provides a promising surgical solution for rectus femoris ruptures.
This case expands the armamentarium for operative management of complex quadriceps injuries.
Further studies may validate this approach for chronic and subacute rectus femoris tears.
