We report a case of 69-year-old female patient who presented with a dislocated insert causing tibial component failure and catastrophic metallosis after 4 years of prosthesis implantation. In case of a trauma history, surgeons must suspect friction noise and motion loss as clinical symptoms indicating dislocation of the insert at the initial postoperative period. Timely diagnosis can prevent catastrophic consequences.

“…There have been a few cases reported in the literature of spontaneous dislocation, however no clear cause has been identified. The most popular opinion is that repeated posterior compressive forces can cause lift off of the anterior rim overtime leading to spontaneous dislocation [2][3][4][5][6] . From a biomechanical perspective, flexion movements particularly when starting from full extension cause greater posterior load as tibial-femoral contact moves in a posterior direction leading to force applied in an antero-superior direction.…”

Dislocation of the polyethylene liner is a rare complication of fixed-bearing total knee arthroplasty with only a few cases described in the literature. This case report describes a 62 year old gentleman with previous total knee arthroplasty (TKA) using a cemented Physica posterior stabilised implant who experienced an anterior dislocation of the polyethylene liner after a fall causing hyperflexion. This is to the best of our knowledge the first case in literature that describes sudden dislocation of the polyethylene liner following traumatic injury.

“…Our case and duplicated saw bone model demonstrated that failure of the locking system resulted in the dislocation of the insert [15]. Dislocation of polyethylene insert is rare and it can easily be overlooked at the early stage [18,19]. Severe damage to either the femoral or tibial component might occur if there was delay in treatment.…”

BackgroundThe mobile bearing knee system was introduced to lessen contact stress on the articular bearing surface and reduce polyethylene wear. The purpose of the current study was to investigate the mid-term results of patients undergoing total knee arthroplasties (TKAs) using Scorpio Plus Mobile Bearing Knee System (Stryker, Mahwah, NJ), and compare the outcomes between patients with osteoarthritis and osteonecrosis (OA·ON group) and patients with rheumatoid arthritis (RA group).MethodsEight males and 58 females were followed up for a period of 4.4- 7.6 years from June 1, 2003 to December 31, 2005. There were 53 knees with osteoarthritis, 17 knees with rheumatoid arthritis, and 6 knees with osteonecrosis. Clinical and radiographic follow- up was done using The Japanese Orthopedic Association knee rating score (JOA score) and Knee Society Total Knee Arthroplasty Roentgenographic Evaluation and Scoring System.ResultsWith regard to the JOA score, there was significant improvement in both groups. The postoperative range of motion was between 0.8°and 116.8° in OA·ON group, and between 0.0° and 113.7° in RA group. There were no significant differences with the radiographic evaluation between two groups. Spontaneous dislocation of a polyethylene insert occurred in one patient, and deep infection was occurred in one patient.ConclusionThere was significant improvement with regard to the clinical and radiographic results of patients undergoing TKAs using the model. The risk of polyethylene insert dislocation related to the mobile bearing TKA is a cause for concern.
