Total knee arthroplasty is a successful procedure to treat pain and functional disability due to osteoarthritis. However, precisely how a total knee arthroplasty changes the kinematics of an osteoarthritic knee is unknown. We used a surgical navigation system to measure normal passive kinematics from 7 embalmed cadaver lower extremities and in vivo intraoperative passive kinematics on 17 patien...
BACKGROUND Management of adolescent patients with end-stage arthritis is challenging. Nonoperative treatments may be ineffective and total knee arthroplasty (TKA) is rarely performed. Currently, minimal long-term data are available on the outcomes in this patient population. Our goal was to describe TKA for patients with end-stage arthritis who were aged 20 years and younger. METHODS The Join...
Eighty-six nonhinged total knee arthroplasties performed between 1971 and 1981 have been reviewed. Fifty-one were of the geometric type and 35 of the anametric type. The use of both units resulted in a statistically and clinically significant improvement in preoperative pain and an increase in functional activities. Three of 51 geometric units developed loose components that required revision. ...
Bone Joint J 2016;98-B:867–73. As the number of younger and more active patients treated with total knee arthroplasty (TKA) continues to increase, consideration of better fixation as a means of improving implant longevity is required. Cemented TKA remains the reference standard with the largest body of evidence and the longest follow-up to support its use. However, cementless TKA, may offer the...
Osteoarthritis is the most common disease of the joints, and joint replacement surgery is often performed on the major lower extremity joints to relieve pain and improve function. While total knee arthroplasty is successful in restoring some degree of function, there are concerns in relation to the progression of osteoarthritis in other lower limb joints. The purpose of this study was to determ...
A cementless femoral component may allow for a smaller surgical incision when a minimally invasive approach is used during primary total knee arthroplasty. Fixation by cement is the gold standard for total knee arthroplasty. The results of cementless total knee arthroplasty are mixed. Cementless femoral components have done well. Although some tibial components have performed well at long-term ...
BACKGROUND Total knee arthroplasty is one of the most clinically successful and cost-effective interventions in medicine. However, implant malalignment, especially in the coronal plane, is a common cause of early failure following total knee arthroplasty. Computer-assisted surgery has been employed during total knee arthroplasty to improve the precision of component alignment. The purpose of th...
Post-patellectomy patients represent a specific subgroup of patients that may develop arthritis and persistent knee pain and potentially require treatment with total knee arthroplasty. This article reviews the treatment and functional outcomes following total knee arthroplasty in patients with prior patellectomy. A case report is presented as an example of the clinical management of a post-pate...
An early diagnosis of popliteal artery pseudoaneurysm-a sequela of popliteal artery trauma-is difficult owing to its late presentation following total knee arthroplasty. The incidence of a popliteal artery pseudoaneurysm with a hematoma presenting only a peripheral nerve injury after total knee arthroplasty is also uncommon in the absence of common diagnostic features such as a pulsatile swelli...
Background: Restoration of neutral alignment of the leg is an important factor affecting the long-term results of total knee arthroplasty. Despite the use of modern instruments in total knee arthroplasty, component malalignment remains a problem. Computer-assisted systems have been developed in order to improve alignment of components. Th e objective of this study was to determine whether the c...
