Total knee arthroplasty (TKR) using a medial capsular approach gives worse results in arthritic knees with valgus deformity than in those in varus, usually because of swelling, poor wound healing and stiffness, instability, recurrent valgus deformity and poor patellar tracking. A technique for replacement TKR of valgus knees using a lateral capsular approach was described several years ago, but...

BACKGROUND Most previous studies on hallux valgus focused on the possible relationship between this deformity and muscles and/or ligaments in the foot and lower leg. Very little is known about the relationship between hallux valgus and alignment of the proximal joints. The aims of the present study were to determine the extent to which lower extremity alignment characteristics of the hip, knee,...

Late valgus deformity after simple fracture of the proximal tibial metaphysis in children, despite adequate initial alignment, was first described by Cozen (1953). It has been suggested in the “check rein” theory that infolding of the periosteum and the pes anserinus at the fracture site may alter the forces on the proximal tibia and lead to deformity. If this is so, then operative removal of t...

A patient with multiple sclerosis (MS) and severe osteoarthritis of the right knee with valgus deformity developed early in the postoperative period a posterior dislocation of the knee after total knee arthroplasty (TKA), due to severe spasm of her hamstring muscles. At revision surgery the posterior cruciate retaining prosthesis was exchanged for a non-linked constrained knee prosthesis. Techn...

Few studies have focused on the possible change in the axial alignment of the lower limb after lateral meniscectomy. Here, we present a patient with valgus deformity of the knee following the partial removal of lateral discoid meniscus. With the distal femur osteotomy and fixation, this complication was treated successfully. This case suggested that we should pay more attention to the axial ali...

BACKGROUND To perform total knee arthroplasty, some surgeons prefer to use a fixed valgus angle, for example 5° or 6°, for the distal femoral cut with every patient. This angle may be appropriate for some patients, but may not be for all. OBJECTIVE To determine the proper angle of the distal femoral cut during total knee arthroplasty (TKA) in Thai patients with osteoarthritis of the knee. M...

Post traumatic tibial valga, also known as Cozen’s phenomenon, is a condition of pathologic knee valgus with variable limb shortening in the affected limb. It late-onset complication following previously healed fracture proximal metaphases. The deforming nature raises much concern for patients and their carers. Despite appearance deformity, child frequently asymptomatic. can be treated successf...

PURPOSE To report long-term results of total knee arthroplasty (TKA) for valgus knees. METHODS 34 women and 19 men aged 39 to 84 (mean, 74) years with valgus knees underwent primary TKA by a senior surgeon. Of the 78 knees, 43, 29, and 6 had type-I, type-II, and type-III valgus deformities, respectively. A preliminary lateral soft-tissue release was performed, and the tibia and femur were pre...

Permanent dislocation of the patella in adults is a rare condition that presents with complete irreducible lateral dislocation of the patella, combined with secondary changes, such as valgus deformity and leg-length discrepancy. Because these secondary changes cannot heal spontaneously after skeletal maturation if left untreated, the patients frequently possess pathology not limited to the knee...

BACKGROUND Primary total knee arthroplasty (TKA) in severe valgus knees may prove challenging, and choice of implant depends on the severity of the valgus deformity and the extent of soft-tissue release. The purpose of this study was to review 8 to 11 years (mean, 10 years) follow-up results of primary TKA for varient-III valgus knee deformity with use of different type implants. METHODS Betw...
