Abstract

Abstract: BACKGROUND: Soft tissue sarcoma (STS) occurs most commonly in the anterior compartment of the thigh. Limb salvage surgery is the mainstay of treatment, however, resections frequently involve muscle sacrifice. This study determines the impact of a single quadriceps muscle sacrifice on daily living functions. This is to assist clinical decision‐making relating to when a functional reconstruction should be offered over simple soft tissue coverage for these defects. METHODS: Patients who underwent single quadriceps resection as part of the management of STS between 2010 and 2020 were selected. Three functional tests were performed: Time Up and Go (TUG), Timed Up and Down Stairs (TUDS) and Toronto Extremity Salvage Score (TESS). The results were compared with age/sex matched healthy reference values and literature cohorts of lower limb STS patients. Correlations between the tests and age and follow‐up duration were determined by the Spearman's test. RESULTS: The mean TESS, TUG and TUDS results of the 13 patients were 89.6%, 9.8 and 1.01 s/step, respectively. These scores were either similar or significantly better than the comparator values. The TESS score showed no statistical significance compared with patients with no muscle resection. TUG and TUDS scores showed significant positive correlation with each other (ρ = 0.885, P = <0.01) and with age (ρ = 0.646, P = 0.017 and ρ = 0.567, P = 0.043, respectively). CONCLUSION: This is the largest documented case series of single quadriceps resection for STS. The study suggests that this group of patients does not show a functional deficit and therefore does not require functional reconstruction. Abstract : The study investigates the functional outcome after single quadriceps muscle resection for the management of soft tissue sarcoma. Timed up and go, timed up and down stairs and Toronto Extremity Salvage Score were used to evaluate both objective and subjective functional outcomes. Results show that no functional deficit was observed in this patient cohort.
