Factors related to stress fracture after unicompartmental knee arthroplasty

Periprosthetic fracture of the tibial plateau after unicompartmental knee arthroplasty.

The authors report three cases of unicompartmental knee arthroplasty (UKA), complicated with peri-operative periprosthetic fracture of the tibial plateau. The surgical technique was held responsible in all cases. The initial treatment was different in every case; all patients ultimately underwent revision total knee arthroplasty with a good functional outcome. The authors emphasise the importan...

Snapping Pes Syndrome after Unicompartmental Knee Arthroplasty

Snapping pes syndrome is defined as a snapping sensation in the medial knee caused by pes anserinus and rarely occurs. Snapping pes syndrome after unicompartmental knee arthroplasty (UKA) has not been reported yet. We experienced two cases with this syndrome after UKA. Conservative treatment was effective in one case, while surgical excision of the gracilis tendon was necessary to relieve painf...

Recurrent hemarthrosis after unicompartmental knee arthroplasty.

Recurrent hemarthrosis after knee arthroplasty can be disabling, requiring adequate and immediate diagnosis and treatment for recovery of symptoms and joint function. The most commonly reported cause is impingement of proliferative synovium between prosthetic components. Although various procedures for hemarthrosis have been reported after knee arthroplasty for patients who do not respond to co...

Unicompartmental Knee Arthroplasty

Unicompartmental knee arthroplasty

The unicompartmental knee arthroplasty is an interesting and potentially beneficial procedure that remains a controversial alternative to total knee arthroplasty and high tibial osteotomy. A critical review of the literature reveals inconsistent results using this compartmental approach to joint resurfacing. Many of the inconsistencies, however, are attributable to improper patient selection, p...
