Tibiofemoral dislocation after primary total knee arthroplasty: a systematic review

Incidence and Risk Factors of In‐Hospital Prosthesis‐Related Complications Following Total Knee Arthroplasty: A Retrospective Nationwide Inpatient Sample Database Study

“…The reported incidence of PRCs after TKA varies mainly according to the category and the corresponding follow‐up period of specific adverse events, such as PJI (0.50%–3.73%), PPF (0.30%–2.50%), mechanical loosening (0.98%), and dislocation (0.15%–0.50%) 1,2,5,10,12,15–22 . Consequently, preoperative identification of patients at increased risk of early PRCs allows for development of strategies with purpose of moderating postoperative outcomes and mitigating the need for TKR 2,5,8–14,18,22 .…”

Consequently, preoperative identification of patients at increased risk of early PRCs allows for development of strategies with purpose of moderating postoperative outcomes and mitigating the need for TKR 2,5,8–14,18,22 . Numerous risk factors of PJI after TKA have been reported in prior literatures including younger age, male, diabetes, rheumatoid arthritis, corticosteroid therapy, blood transfusion, alcohol abuse, drug abuse, smoking, posttraumatic arthritis, prior knee arthroscopy (PKA), chronic pulmonary disease, liver disease, peripheral vascular disease, coagulopathy, malignancy, myocardial infarction, urinary tract infection, and wound dehiscence 1,2,11,12,14–16,21,23–27 .…”

“…Additionally, the risk factors of mechanical loosening such as younger age, PKA, diabetes, and hyperglycemia also have been identified 17,23,26 . Previous findings suggest that obesity, female, and neuropsychiatric disorders may increase the risk of dislocation 18,19 .…”

Cruciate-Retaining vs Posterior-Stabilized Antibiotic Cement Articulating Spacers for Two-Stage Revision of Prosthetic Knee Infection: A Retrospective Cohort Study

“…Compared with CR TKA, PS TKA required an additional resection of the femoral box bone, which increased the surgical time, decreased the bone volume, and increased the risk of fracture [41]. Furthermore, there was post-cam mechanism polyethylene wear and a risk of dislocation [42,43], and the patella clunk syndrome might have occurred [44]. For many TKA brands, anterior-lipped ultracongruent (UC) J o u r n a l P r e -p r o o f inserts are available for when PCLs are damaged or resected, but increased constraint is provided by a "deep dish" polyethylene geometry instead of a post-cam mechanism [45][46][47][48][49].…”

Literature review of the causes of pain following total knee replacement surgery: prosthesis, inflammation and arthrofibrosis

“…In a systematic review by Rouquette et al 44 exploring the causes of tibiofemoral dislocation (a rare but serious form of instability) after TKR, key factors for tibiofemoral dislocation included comorbidities such as obesity and pre-operative deformity, and intra-operative iatrogenic destabilization. Higher rates of dislocation recurrence were associated with non-operative management such as splints.…”
