John N. Insall was a pioneer in the field of knee surgery. He was a rare individual who accomplished unparalleled levels of success as a surgeon, designer, and teacher. During the past 4 decades, he was instrumental in evolving total knee arthroplasty to its current state of excellence. Insall's impact on orthopaedics is felt by all who have come in contact with him.

We construct 16 reflection groups Γ acting on symmetric domains $\mathcal {D}$ of Cartan type IV, for which the graded algebras modular forms are freely generated by same weight, and in particular Satake-Baily-Borel compactification {D}/ {\Gamma }$ is isomorphic to a projective space. Four these previously known results Freitag-Salvati Manni, Matsumoto, Perna Runge. In addition we find several ...

We present a new proof that O2 is a multiple context-free language. It contrasts with a recent proof by Salvati (2015) in its avoidance of concepts that seem specific to two-dimensional geometry, such as the complex exponential function. Our simple proof creates realistic prospects of widening the results to higher dimensions. This finding is of central importance to the relation between extrem...

We give a solution to the weak Schottky problem for genus five Jacobians with vanishing theta null, answering question of Grushevsky and Salvati Manni. More precisely, we show that if principally polarized abelian variety dimension has null quadric tangent cone rank at most three, then it is in Jacobian locus, up extra irreducible components. employ degeneration argument, together study ramific...

Introduction: Trochanteric fractures are among the most common injuries necessitating hospital admission. Regardless type of fracture, trochanteric can lead to substantial morbidity and mortality, especially in elderly patients. Surgery has been mainstay treatment for these allow early mobilization patient. Among surgical treatment, dynamic hip screw (DHS) as extramedullary power transmission s...

Patellar Tendon (PT) rupture is an uncommon injury of the knee extensors. Majority PT ruptures occur at insertion site, on inferior pole patella as avulsion injury, mostly in males <40 years age and involving sports persons or accidental cases. A case series 10 cases neglected were managed with primary repair along augmentation semitendinosus gracilis (Hamstring tendons) graft. Patient follo...

Two patients with Kabuki make-up syndrome with bilateral recurrent dislocation of the patella are presented. They had generalized ligamentous laxity and patellofemoral dysplasia. Both developed patellar dislocation in adolescence and required surgery, with medial transfer of the tibial tuberosity associated with vastus medialis plasty (Insall technique). One postoperative complication occurred ...

We reviewed 41 knees after arthroscopic lateral release for recurrent dislocation of the patella at a mean follow-up of four years, and graded the results according to the criteria of Crosby and Insall (1976). There were no dislocations after operation in 28 knees (68%); the less satisfactory results were in patients with subluxation of the patella on extension of the knee and those with genera...
