Clinical outcomes of arthroscopic partial meniscectomy at 10 years follow up - A retrospective cohort study

Abstract

In recent times, the advent of newer meniscal repair systems and studies thereof seem to have implied that meniscectomy procedures should be abandoned or used only as a last resort procedure in most patients. This study was done to report the outcomes of partial meniscectomy done in indicated patients by a skilled arthroscopic surgeon at a long-term follow-up of 10 years. The indications and the appropriate strategy for performing this procedure are also described. One hundred consecutive patients who underwent arthroscopic partial meniscectomy (APM) over one year were evaluated 10 years later for functional and clinical outcomes. A retrospective case series of 100 consecutive patients was conducted to study the clinical outcome of APM after 10 years. Their mean age was 41.23 ± 7.81 years. 70% of the selected patients were male. Medial meniscus involvement was the most common (73%). At their 10-year follow-up, the majority of cases were asymptomatic (72%), with a mean international knee documentation committee score of 86.90 ± 5.51. Mean Tegner Lysholm Knee score was 90.05 ± 10.21, the Western Ontario and McMaster Universities Arthritis Index score was 8.83 ± 6.19, and the Western Ontario meniscal evaluation tool score was 85.54 ± 10.91. The subjective assessment after surgery was “excellent” in the majority of patients (48%). With proper patient selection and accurate decision-making, patients operated with APM for isolated meniscus tears can return to their daily routine activities and have good clinical and functional outcomes. The technique of performing arthroscopy and the skill set of the operating surgeon may perhaps also be an important criterion influencing the outcomes.
