Background: Stemless total shoulder arthroplasty (TSA) was approved for use in the United States in 2015, and there remains a paucity of data on its performance in this market. Decreased operative time without compromise of clinical outcomes is a theoretical advantage of stemless TSA, but no studies have evaluated this in a comparative study to date. Herein, the operative times and clinical outcomes of stemless vs.

Purpose: To determine (1) subjective results and incidence of symptomatic medial meniscus tears (MMTs) in patients treated with trephination alone compared with a control group without meniscus tears and (2) if trephination treatment resulted in a higher incidence of knee arthritis compared with controls with intact menisci.

Methods: Between 1997 and 2010, 419 patients met the inclusion criteria of having an isolated anterior cruciate ligament (ACL) tear, peripheral vertical nondegenerative MMT treated with trephination alone, no lateral meniscus tears, normal radiographs before surgery, and no bilateral knee involvement. A control group of 462 patients included patients who met the same criteria but without MMT.
