Barras LA, Pareek A, Parkes CW, et al. - Researchers conducted the study for assessing both the potential etiologies and resultant outcomes of patients who develop subchondral insufficiency fractures of the knee (SIFK) following arthroscopy. The sample consisted of all patients with an MRI diagnosis of SIFK following arthroscopic meniscectomy and chondroplasty over a 12-year period. For this retrospective review, 28 patients were involved with a mean age of 61 years and a mean follow-up of 5.7 years. Data reported that the survival-free of conversion to arthroplasty was 57%, 45%, and 40% at 1-, 2-, and 5-years, respectively. Postarthroscopic SIFK is most common in the medial compartment, especially in those who have had a previous meniscectomy. The presence of root and radial meniscus tears is notable in these patients (75%). Finally, there is a high rate of arthrosis progression (33%) and eventual conversion to arthroplasty.
