“… 8 Hinge type contrite implants with rotating components are a good option for TKA revision where there is significative bone loss and ligament instability. 12 - 15 , 20 , 21 Sanguineti et al, 12 with 20 cases of TKA revision surgeries using the Endo-Model rotating-hinge prosthesis (Waldemar Link GmbH and Co., Hamburg, Germany), Neumann et al 22 , with 24 cases using the NexGen Rotating Hinge Knee (Zimmer Biomet Inc., Warsaw, IN, USA) and Bistolfi et al 14 with 50 cases also using the Endo-Model prosthesis, are some of the largest series showing the follow-up of patients submitted to TKA revision with this type of implant. These implants, however, although also of the hinge type, have a quite different design than the implants used in this study.…”

Objective: To evaluate the results of total knee arthoplasty revisions performed in high complexity cases, with large bone defects or serious ligament deficiencies using a constrained implant hinge associated to a rotating tibial basis. Methods: We evaluated 11 patients in which we used the constrained implant hinge associated to rotating tibial basis, with minimum follow-up of two years. The indications for the procedure included instability, septic loosening, late postoperative infection without loosening and periprosthetic fracture. We evaluated the knee range of movement and functional outcomes by the Knee Society Score (KSS) e Knee Injury and Osteoarthritis Outcome Score (KOOS), besides the presence of complications. Results: All patients achieved 5o to 85o minimum range of motion at 1 year postoperatively and, in the present evaluation, KSS ranged from 67 to 95. Three patients had no complications until the last evaluation and two patients required implant revision. Conclusion: Despite the complications rate observed, the functional result were acceptable for most patients, and it proved being a viable alternative, especially for patients with low functional demand. Level of Evidence IV, Case Series.

“…Initially, a high rate of failure was described with rotatinghinge knee implants, whereas some good results have been described more recently. 1,5,[13][14][15][16] Nevertheless, several authors report discouraging results, 2,17,18 and many think that the hinge transfers high stresses to the implant-bone interface and causes loosening.…”

“…Although the complication rate was high, it was similar to rates reported in the literature for this type of revision surgery. 4,16,19 Deficit of the external popliteal sciatic nerve is not a frequent complication in knee arthroplasty but can occur in revision surgery. The authors preferred a wide cementation because the cement is easy to handle, can fill almost any kind of defect, is stable when polymerized, and gives excellent metaepiphyseal fixation.…”

Rotating-hinge knee implants are used for revision total knee arthroplasty in patients with severe ligament instability and bone loss. This study evaluated the outcomes of a series of rotating-hinge knees. Thirty-one NexGen Rotating Hinge Knees (Zimmer, Warsaw, Indiana) were implanted in 29 patients (2 bilateral), with an average age of 72.8 years. Indications for surgery were aseptic loosening (n=23), septic loosenings (n=4), tibiofemoral instability (n=3), and wear (n=1). The Hospital for Special Surgery Knee Score and the Knee Society Roentgenographic Evaluation System were used. Statistical and cumulative survival rate analyses were performed. Average follow-up was 60.3 months (range, 32-100 months). The Hospital for Special Surgery Knee Score results indicated statistically significant improvement; the total score increased from 65.5 preoperatively to 88.4 postoperatively. Average range of motion increased from 90.9° preoperatively to 114.4° postoperatively. Radiographs showed no periprosthetic bone fractures or implant ruptures. Radiolucent lines were found in 20 of 26 patients and were progressive in 2 (both revised). Complications occurred in 10 patients. The rigidity of the hinge may be associated with a risk of aseptic loosening due to the increased stress transfer to the bone from the prosthesis through the locked hinge. Rotating-hinge knee implants provided acceptable mid-term outcomes for revision knee surgery with ligamentous instability. They are not at higher risk for early loosening unless short tibial stems are used. The high percentage of failures is more related to the complex surgery and to the status of the patients than to the hinged mechanism.

“…9,10 Survivorship will also be reduced due to the increased stress placed at the implant-bone interface, secondary to the less normal kinematics of the joint and resulting increased forces generated. 11 Even the scores for clinical results seem to be worse than in conventional non-constrained replacement of the knee.…”

The aim of the study was to evaluate the mid-term clinical results and survivorship of a rotating-hinge knee prosthesis (LINK® Endo-Model) in difficult primary and complex revision situations. Results after primary implantation were compared with those of revision procedures. Forty-nine prostheses in 45 patients were reviewed clinically during follow up. Twenty-one of these were implanted in primary and 28 in revision situations. Outcome was evaluated using commonly used scores (Knee Society, UCLA Activity, Lequesne) and a visual analog scale after a mean follow up of 56±37 months for 49 prostheses. Implant survival was analyzed using the Kaplan-Meier method. There were no significant differences in clinical examination and evaluation scores between the two groups (P>0.05). Survival rates at final follow up were 95% after primary implantation and 76% in revision procedures. The risk of prosthesis loss (odds ratio 5.7) was significantly higher after revision procedures (P=0.004). These data suggest that rotating-hinge knee prostheses provided good clinical and functional results in selected cases of advanced primary gonarthrosis associated with severe bone loss, ligamentous instability or comminuted fractures. They also provide good results in revision situations. However, the failure rate was significantly higher in cases of revision surgery.
