Robert Insall was born in London in 1965, into a family of architects, musicians and historians. To their great surprise, he was obviously scientifically inclined from an early age. He did a B.A. at Cambridge University, then stuck around in Cambridge for a Ph.D., where he got interested in Dictyostelium, followed by a postdoc in Johns Hopkins, where he got interested in chemotaxis and cell mov...

Objectives: To evaluate the effect of amount correction on postoperative changes in PTS (posterior tibial slope), PH (patellar height), and clinical outcomes following biplanar OWHTO (open-wedge high osteotomy). Method: This study included 79 knees (32 left 47 right) patients (mean age 60.28 ± 4.2 years, 24 males, 55 females) with varus malalignment symptomatic isolated medial joint osteoarthri...

Introduction The utilization of hip arthrodesis for the treatment of end-stage hip degenerative joint disease has significantly declined due to the success of total hip arthroplasty. In 2010, the Centers for Disease Control (CDC) reported that over 332,000 THA procedures were performed in the United States alone. Although fewer patients are undergoing primary hip fusion, patients that have prev...

BACKGROUND High tibial osteotomy (HTO) is a well-established treatment for unicompartmental gonarthrosis of the knee, but its durability and complications remain controversial. We previously introduced a novel dome-shaped HTO, and the long-term follow-up results using this technique are analyzed in this study. METHODS We treated 25 varus knees in 22 patients with medial gonarthrosis, using a ...

Gonarthrosis in the relatively young and active population causes major daily discomfort and disability. If the arthritic process is mainly limited to the medial compartment, the axis of a varus knee can be realigned laterally with high tibial osteotomy to unload the medial compartment and allow some cartilage regeneration and pain relief. This study describes the outcomes of patients who under...

OBJECTIVE The methods most used for patellar height measurement were compared with the plateau-patella angle method. METHODS A cross-sectional study was conducted, in which lateral-view radiographs of the knee were evaluated using the three methods already established in the literature: Insall-Salvati (IS), Blackburne-Peel (BP) and Caton-Deschamps (CD). These were compared with the plateau-pa...

BACKGROUND The Koshino (KI) and Caton-Deschamps (CDI) indices are used to measure patellar height in children, with the CDI showing excellent reliability in typically developing (TD) children. Reliability of such measures in children with cerebral palsy (CP) and spina bifida (SB) is unknown. METHODS Lateral knee radiographs were reviewed retrospectively for children with TD (n = 49), CP (n = ...

BACKGROUND Patellar stabilizing braces are used to alleviate pain and prevent subluxation/dislocation by having biomechanical effects in terms of improved patellar tracking. The purpose of this study is to analyze the effects of the dynamic patellar realignment brace, Patella Pro (Otto Bock GmbH, Duderstadt, Germany), on disease determinants in subjects with patellofemoral instability using upr...

INTRODUCTION Although patellar tendon injuries are common but chronic patellar tendon rupture are rare injuries but severely disabling. Problems associated with this injury are scar formation, atrophy and contracture of the quadriceps, poor quality of remaining reabsorbed tendon, inadequate soft tissue, proximal patellar migration and prolonged post operative immobilization. Hence these injurie...
