Aims To evaluate: (1) objective quantification of ligament balancing in total knee arthroplasty, (2) types and effectiveness of additional procedures to compartment pressure, and (3) change of pressure values in both compartment throughout the range of motion in total knee arthroplasty.Methods Eighty-four patients underwent total knee arthroplasty (TKA) using VERASENSE Knee System. TKA was performed by two techniques. Compartment pressure was recorded through the range of motion (ROM) initially, after each additional procedure, and after final implantation. Balanced knees were defined as when the compartment pressure difference was less than 15 pounds.Results Thirty patients (35.7%) showed “balanced” knee on initial pressure measurement. Modified gap balancing TKAs showed significantly higher proportion of “balanced” knee than measured-resection TKAs (P = 0.004). Both medial and lateral compartment pressure were generally decreased on both TKA methods. Linear correlation showed statistically significant through ROM on both compartment. Total 66 additional ligament balancing procedures were performed.Conclusion Using the objective orthosensor, we were able to obtain 94% of well-balanced total knee arthroplasty finally. Furthermore, acquired objective data can lead to proper ligament balancing for both experienced and young surgeons and consequently reduce the complications associate with soft tissue imbalance in the future.

Neurovascular Damage

Ligament balancing affects many of the postoperative criteria for a successful knee replacement. A balanced knee contributes to improved alignment and stability. Ligament balancing helps reduce wear and loosening of the joint. A patient with a balanced knee is more likely to have increased range of motion and proprioception, and decreased pain. All these factors help minimize the need for revision surgery. Complications associated with ligament balancing can include instability caused by over-balancing and the possibility of neurovascular damage during or as a result of ligament balancing. This article attempts to summarize the literature, to define a balanced knee, and outline the benefits and possible complications of ligament balancing. Different techniques, sequences, and tools used in ligament balancing, and their relevance in correcting various deformities are reviewed.

Abstract The aim of this retrospective cohort study was to compare home physiotherapy with or without supervision of physiotherapist for assessing manipulation under anaesthesia after total knee arthroplasty. Methods A total of 900 patients (including 810 females and 90 males) who had undergone total knee arthroplasty were divided into group A (n = 300) and group B (n = 600). Patients in group A had home physiotherapy on their own after discharge from hospital. The physiotherapist did not visit them at home. Patients in group B received home physiotherapy under supervision of physiotherapist for 6 weeks after discharge from hospital. Patients’ age, range of motion of the knee, and forgotten joint score-12 were assessed. A p < 0.05 was considered statistically significant. Results In group A, the mean age was 69.1 ± 14.3 years (range: 58 to 82 years); in group B, the mean age was 66.5 ± 15.7 years (range: 56 to 83 years) (p > 0.05). Preoperatively, the mean range of motion of the knee in group A and B was 95.8° ± 18.1° and 95.4° ± 17.8°, respectively (p > 0.05). The mean forgotten joint score-12 of group A and B were 11.90 ± 11.3 and 11.72 ± 12.1 (p > 0.05), respectively. Six weeks after total knee arthroplasty, the mean ROM of the knee in group A and B was 109.7° ± 22.3° and 121° ± 21.5°, respectively (p < 0.05). The mean postoperative forgotten joint score-12 of the group A and B was 24.5 ± 16.4 and 25.6 ± 17.4, respectively (p > 0.05). The rate of manipulation under anaesthesia was 3% in group A and 0.2% in group B (p < 0.05). Conclusion After total knee arthroplasty, frequent physiotherapist’s instruction helps the patients improve knee exercises and therefore decrease the risk of revision surgery. The home physiotherapy under supervision of physiotherapist lowers the rate of manipulation under anaesthesia. Level of evidence Therapeutic study, Level IIa.

AbstractThe posterior tibial slope (PTS) is usually adjusted by less than 5 degrees, without considering its individual difference, during posterior cruciate-substituting (PS) total knee arthroplasty (TKA). The effect of these individual changes of PTS would be important because clinical results depending on postoperative PTS were reported conflictingly. We investigated the effect of the change in PTS on the postoperative range of motion (ROM) and clinical scores after PS TKA. We retrospectively reviewed 164 knees from 107 patients who underwent PS TKA with a 2-year follow-up. We analyzed the preoperative and postoperative PTS, ROM, visual analog scale pain scale, Western Ontario and McMaster University Index (WOMAC), Hospital for Special Surgery Knee Score, Knee Society Score, and Forgotten Joint Score (FJS). The association of the absolute change in PTS with ROM and clinical scores was analyzed using correlation analysis and multiple regression analysis. As a result, the mean PTS and mean ROM changed from 9.6 ±  3.4 and 120.1 ±  15.4 degrees preoperatively to 2.0 ±  1.3 and 128.4 ±  9.3 degrees postoperatively, and the mean PTS change was 7.6 ±  3.5 degrees. The PTS change had no statistically significant association with the postoperative ROM and clinical scoring systems, although it did have a weak positive correlation with WOMAC function, No 10 (difficulty in rising from sitting) (correlation coefficient = 0.342, p = 0.041), and moderate positive correlation with the FJS, No. 6 (awareness when climbing stairs) (correlation coefficient = 0.470, p = 0.001). The authors concluded that the amount of change in PTS did not affect the postoperative ROM and clinical scores, although proximal tibial resection with a constant target of PTS resulted in individually different changes in the PTS after PS TKA,

Intro- For TKA, there are two types of bearing designs: xed-bearing and mobile-bearing. Round femoral components articulate with a relatively at tibial articular surface in a xed-bearing knee design. Because the insert does not hinder the natural movements of the femoral component, the mobile-bearing (MB) TKA design is thought to allow more exibility of motion than the xed-bearing (FB) variety. Aim and objective: To compare xed bearing and mobile bearing total knee arthroplasty. Material and methods:This study is a prospective type of study done at Seth GS medical college Mumbai, Department of Orthopaedics during August 2019 to June 2021 on patients undergoing total knee arthroplasty. Patients who were to undergo total knee arthroplasty were invited to take part in the study. This study, done on them was explained in detail to them. An informed consent was obtained. Patients fullling the inclusion criteria were listed. Result: Range of motion achieved after mobile arthroplasty was 123.62±2.94 and in xed arthroplasty it was 121.96±2.74. Pain after last follow up in mobile arthroplasty was 48.83±0.62 and for xed arthroplasty was 47.39±0.86. Flexion gap after last follow up in mobile arthroplasty was 24.13±0.45 and in xed was 24.02±0.45. Stability was almost similar in both mobile and xed arthroplasty. Conclusions: there is no signicant difference between xed arthroplasty and mobile arthroplasty as far as Range of motion, Pain ,Flexion gap. Stability was almost similar in both mobile and xed arthroplasty.
