One of the most controversial issues in total knee replacement is whether or not to resurface the patella. In order to determine the effects of different designs of femoral component on the conformity of the patellofemoral joint, five different knee prostheses were investigated. These were Low Contact Stress, the Miller-Galante II, the NexGen, the Porous-Coated Anatomic, and the Total Condylar ...

The Insall-Salvati method of determining the position of the patella by radiography was employed in fifty-one patients with chondromalacia patellae that had been proved at arthrotomy. There was no definite relationship between chondromalacia patellae and patella alta. There was, however, a highly significant statistical difference between the ratio of the length of the patella to that of the pa...

Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for kneeosteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare theshort-term clinical outcomes of TKA performed with and without the patella resurfacing.Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were random...

Background This study investigated the presence of bursitis in the medial compartment of the knee (pes anserine, semimembranosus-tibial collateral ligament, and medial collateral ligament bursa) in osteoarthritis, chondromalacia patella and medial meniscal tears. Patients and methods Radiological findings of 100 patients undergoing magnetic resonance imaging with a preliminary diagnosis of kn...

Racial differences exist in the dimensions of structures and the commercially available prostheses are designed based on the Caucasians. In this context, the goal of the present investigation was to determine the gender wise measurements of patella bone in South Indians. The present study included axial magnetic resonance images of the knee joint from 140 South Indian adults (70 males, 70 femal...

The current view of skeletal patterning fails to explain the formation of sesamoid bones. These small bones, which facilitate musculoskeletal function, are exceptionally embedded within tendons. Although their structural design has long puzzled researchers, only a limitedmodel for sesamoid bone development has emerged. To date, sesamoids are thought to develop inside tendons in response to mech...

BACKGROUND Graft fixation is critical to the restoration of the medial patella of femoral ligament function and long-term success. Numerous fixations at the patella have been described, while the complications including patellar fractures, violation of the posterior patella and delay of tendon-to-bone healing remain significant challenges. Here, we describe a safe and firm fixation at the patel...

Conventional operative treatments of patella fractures are frequently associated with implant failure or displacement. Recent biomechanical studies showed that the orientation of the wire loop and the site of the wire twist can affect the fixation strength. The purpose of this study was to compare the clinical outcome of the tension band technique with loops in different orientations and differ...
