Abstract

Background

Some patients submitted to isolated ACL reconstruction may have symptomatic postoperative rotational instability. The objective of this study was to evaluate a population with mild rotatory instability after ACL reconstruction, which was submitted to an isolated extra-articular procedure.

Methods

Patients submitted to an isolated extra-articular procedure after ACL reconstruction were retrospectively evaluated. Only patients presenting anterior knee instability of less than 5 mm, pivot-shift of a maximum of 1+, and ACL graft intact were included. Demographic data, physical examination and subjective functional scales were evaluated.

Results

Twenty patients were included. The mean age was 27.0 ± 7.3 years. The follow up time after the extra-articular procedure was 27.5 ± 6.2 months. The KT-1000 decreased from 3.0 mm ± 0.7 mm to 2 mm ± 0.4 mm (P = 0.00016). The pivot-shift improved from 100% of grade 1 positivity to 30% (6/20 patients) of grade 1 positivity (P < 0.0001). The IKDC showed no difference (74.4 ± 11.8 vs. 87.6 ± 5.8; P = 0.087), but the percentage of patients who passed the PASS IKDC cut-off value increased from 45% (9/20) to 95% (19/20) (P = 0.0012). The Lysholm increased from 81.1 ± 7.3 to 91.2 ± 5.7 (P = 0.0001).

Conclusions

Patients submitted to an isolated extra-articular procedure due to residual instability after ACL reconstruction showed improvement in physical examination (KT-1000 and pivot-shift) and subjective functional scales. This procedure can be considered for a specific population with minor instabilities and intact ACL graft, avoiding a complete ACL revision.

期刊介绍： The Knee is an international journal publishing studies on the clinical treatment and fundamental biomechanical characteristics of this joint. The aim of the journal is to provide a vehicle relevant to surgeons, biomedical engineers, imaging specialists, materials scientists, rehabilitation personnel and all those with an interest in the knee. The topics covered include, but are not limited to: • Anatomy, physiology, morphology and biochemistry; • Biomechanical studies; • Advances in the development of prosthetic, orthotic and augmentation devices; • Imaging and diagnostic techniques; • Pathology; • Trauma; • Surgery; • Rehabilitation.
