A 10-year survivorship of 100% was reported for patients with PFC cruciate-retaining prostheses. Beyond 10 years, we observed additional polyethylene wear likely related to thin liners gamma-irradiated in air and were concerned this wear might predispose to implant construct failure.
There is controversial evidence regarding whether foot orthoses or knee braces improve pain and function or correct malalignment in selected patients with osteoarthritis (OA) of the medial knee compartment. However, insoles are safe and less costly than knee bracing if they relieve pain or improve function.
Treating ACL injuries in prepubescent patients requires balancing the risk of chondral and meniscal injuries associated with delaying treatment against the risk of growth disturbance from early surgical reconstruction. Multiple physeal respecting techniques have been described to address this vulnerable population; however, none restore the native ACL attachments while keeping the graft and fixation entirely in the epiphysis.
Osteonecrosis is a complication of corticosteroid therapy with limited treatment options in young, active patients. These options include debridement, core decompression, osteotomy, allografting, and partial or total knee replacement. Few studies exist regarding the use of osteochondral allografts for treatment of steroid-associated osteonecrosis.
Subcutaneous versus Intraarticular Indwelling Closed Suction Drainage after TKA: A Randomized Controlled Trial
TKA can involve substantial bleeding, and the issue regarding whether vacuum drainage should be used during TKA continues to be debated as both methods have disadvantages.
Radiographic Prevalence of Femoroacetabular Impingement in a Young Population with Hip Complaints Is High
Femoroacetabular impingement (FAI) is reportedly a prearthritic condition in young adults that can progress to osteoarthritis. However, the prevalence of FAI is unknown in the young, active population presenting with hip complaints.
Do Porous Tantalum Implants Help Preserve Bone?: Evaluation of Tibial Bone Density Surrounding Tantalum Tibial Implants in TKA
TKA with conventional metal-backed tibial implants subjects the tibial metaphysis to stress shielding, with resultant loss of bone density.
Although TKA reliably reduces pain from knee osteoarthritis, full recovery of muscle strength and physical function to normal levels is rare. We presumed that a better understanding of acute changes in hamstrings and quadriceps muscle performance would allow us to enhance early rehabilitation after TKA and improve long-term function.
There is limited information regarding revision total knee arthroplasty (TKA) with respect to etiology, outcome, and long-term survival comparing different implant types.
