PURPOSE We systematically reviewed the evaluated efficacy of medial patellofemoral ligament (MPFL) reconstruction, rehabilitation, and patient outcomes for safely returning patients to sports. METHODS We performed a literature search using the Ovid Medline database from 1950 to present, as well as the SportDiscus and CINAHL (Cumulative Index to Nursing(More)
This study compares the relative risk of revision and associated risk factors after total or unicompartmental knee arthroplasty (TKA or UKA) in the Medicare population. A total of 61 767 TKA and 2848 UKA patients were identified. Reviewed data included type of treatment, gender, age, race, Charlson Index for comorbidity, length of stay, Medicare buy-in for(More)
A type of tridiagonal pair is considered, said to be mild of q-Serre type. It is shown that these tridiagonal pairs induce the structure of a quantum affine algebra Uq(sl 2)-module on their underlying vector space. This is done by presenting an explicit basis for the underlying vector space and describing the Uq(sl 2)-action on that basis. 1. Introduction.(More)
We investigate a connection between distance-regular graphs and Uq (sl(2)), the quantum universal enveloping algebra of the Lie algebra sl(2). Let 0 be a distance-regular graph with diameter d ≥ 3 and valency k ≥ 3, and assume0 is not isomorphic to the d-cube. Fix a vertex x of0, and let T = T (x) denote the Terwilliger algebra of 0 with respect to x . Fix(More)
