Total Knee Arthroplasty (TKA) is a very impelling treatment for severe osteoarthritis. But, prosthesis longevity along with clinical and functional outcome of patients are intricately related to proper alignment and position of the prosthesis and how perfectly the artificial joint can mimic the native knee anatomy and kinematics. To minimize outliers and improve accuracy, precision and patients’ outcome, promising new technologies have been developed in knee arthroplasty. TKA is advancing by leaps and bounds with the advent and introduction and application of technologies in its domain. The aim of this article is to put up and brief about the technologies in TKA, their concepts, advantages, and limitations.

Background: Severe bilateral Fixed flexion deformity of the knees resulting from irreversible joint damage is a disabling complication of long-standing rheumatoid arthritis, associated with loss of ambulatory ability. While Total knee Arthroplasty is an effective treatment for such patients, it poses significant intra-operative technical demands and challenges with post-operative rehabilitation.
Method: We report a case of Severe Fixed flexion deformity of both knees in a 46-year-old male with long-standing rheumatoid arthritis, non-ambulatory since 5 years, treated by sequential total knee arthroplasty.
Results: Treating Severe bilateral Fixed flexion deformities in a non-ambulatory patient by sequential total knee Arthroplasty using standard implants yielded complete deformity correction and pain-free restoration of active range of motion in both knees with stable independent ambulation and complete restoration of lower limb function within 3 months of surgery.
Conclusion: Our case is particularly remarkable for complete restoration of stable, pain-free restoration of ambulation within 3months in a patient with severe bilateral knee fixed flexion deformities who had been non-ambulatory for 5 years preceding his bilateral sequential total knee arthroplasty.

Acute arterial occlusion, a rare complication after total knee arthroplasty (TKA), reportedly has an incidence of 0.03–0.17% which if undetected can result in limb loss. Cases of acute arterial occlusion following TKA reported in the literature have been mainly attributed to the iatrogenic popliteal artery injury. It is important to understand the mechanism of occlusion as it can lead to limb-threatening ischemia. The use of tourniquet and manipulation of the knee joint in an elderly with arteriosclerosis may induce disruption of an atheromatous plaque that could lead to arterial occlusion. Here, we report a rare case of arterial occlusion ofthe femoral artery post-TKA.

Total knee arthroplasty (TKA) is a common surgery that reduces pain and significantly improves function and quality of life in patients with knee disorders. Drains in TKR have been used historically for the theoretical benefit of preventing wound hematoma, improving wound healing, and preventing infection. However, literature available to support these beliefs is sparse. The purpose of our study was to assess if a patient undergoing a TKA would benefit from a wound drainage system.
Materials and Methods: Forty-two patients who underwent primary total knee replacement were included in the study; 23 knees in the drained group and 23 knees in the non-drained group. Both the groups had their coagulation workup done and were given deep venous thrombosis prophylaxis as per protocol. A single wound drain system was placed in those patients enrolled in the group with the drains. The outcome was compared between the two groups in terms of blood loss, transfusion requirements, and progression of rehabilitation.
Results: The median drop in Hb was higher in the drained group (2.4 g/dL) compared to the non-drained group (1 g/dL), which statistical analysis was found to be significant (P < 0.001). In the drained group, 65.2% of cases required transfusion, whereas only 21.7% of cases in the non-drained group required transfusions. This was found to be statistically significant (P = 0.01). There was no significant difference in the visual analog score pain scores between the two groups in the post-operative period (P = 0.109). The number of days required to achieve active straight leg raise and knee flexion of 90 degrees was also more in the drained group, which was statistically significant (P < 0.05). The number of days taken for suture removal was found to be higher in the drained group (mean = 12.71) versus the non-drained group (mean = 12.04), and this was found to have statistical significance (P < 0.001).
Conclusions: In our study, the use of a closed drainage system in total knee replacement was associated with higher blood loss postoperatively which essentially translated to an increased requirement of blood transfusions. The progression of wound healing and achievement of post-operative rehabilitation goals were found to be better in the group without the wound drainage system. Although post-operative pain remained to be the same when compared between both the groups.( Kindly review the sentence as it seems to be incomplete.)
