Purpose:
Quadriceps tendon disruption post-total knee arthroplasty (TKA) is rare. Existing reconstruction procedures use allografts or synthetic meshes with varied success. This study evaluates outcomes with autogenous peroneal tendon grafts, a cost-effective alternative, compared to synthetic polypropylene mesh for quadriceps reconstruction.
Methods:
16 patients who underwent extensor mechanism reconstruction between 2017 and 2021were retrospectively analysed. Parameters evaluated included type of reconstruction, extensor lag, IKDC (International Knee Documentation Committee) Score and AOFAS-Hindfoot-score (American Orthopaedic Foot and Ankle Society).
Results:
At final follow-up, extensor lag for peroneal autograft group was 6.6° ± 1.5 and for synthetic polypropylene mesh group, 7.2° ± 0.7. Both groups improved in IKDC score (p < 0.01) AOFAS-Hindfoot-score was comparable for peroneal autograft patients with opposite side (p = 0.15).
Conclusions:
Autogenous peroneal tendon graft for quadriceps reconstruction could be viable, cost-effective alternative to allografts or synthetic meshes, with good clinical outcomes.
Graphical Abstract:
Graphical abstract depicting the harvesting of the peronei grafts and their passage through the quadriceps tendon. Sonographic image showing the preoperative presence of a gap in the quadriceps tendon which is reconstructed post-operatively.
