Letter to the Editor: “Comparison of early post-operative complications following unilateral or single-stage bilateral unicompartmental knee arthroplasty”
We read with great interest the article published by Sakka et al. [1] which aimed to compare the 90-day postoperative complications between patients undergoing unilateral unicompartmental knee arthroplasty (UKA) and those undergoing single-stage bilateral UKA (SSBUKA). In their retrospective comparative study, the authors found that there was no difference in the incidence of local or systemic complications between the two groups. They also found that the incidence of nausea was lower and the proportion of patients discharged to home was higher in the unilateral group as compared with the bilateral group. (Source: The Knee)

Characteristic kinematics of floor-sitting activities after posterior-stabilized total knee arthroplasty determined using model-based shape-matching techniques
Detailed kinematics of floor-sitting activities after total knee arthroplasty (TKA) have not been well explored. Knee kinematics of cross-legged sitting, seiza-sitting, and side-sitting after TKA were examined to clarify the differences in tibiofemoral kinematics of each activity. (Source: The Knee)

Revision knee replacement for prosthetic joint infection: Epidemiology, clinical outcomes and health-economic considerations
Prosthetic joint infection (PJI) is a devastating complication of knee replacement surgery. Recent evidence has shown that the burden of disease is increasing as more and more knee replacement procedures are performed. The current incidence of revision total knee replacement (TKR) for PJI is estimated at 7.5 cases per 1000 primary joint replacement procedures at 10 years. Revision TKR for PJI is complex surgery, and is associated to a high rate of post-operative complications. The 5-year patient mortality is comparable to some common cancer diagnoses, and more than 15% of patients require re-revision by 10 years. (Source: The Knee)

Prosthetic joint infection of revision knee replacement: Epidemiology, outcomes and health economic analysis
Peri-prosthetic joint infection remains one of the most devastating complications of knee arthroplasty surgery. As the number of primary knee joint replacements performed in the UK increases the number of PJI case increases. The rate of infection in the UK is around 7.5 per 1000 (0.8%) but there is some evidence to suggest that this figure is increasing. The complications seen following revision surgery for PJI are greater than those seen after primary knee replacement. There is a significant increased mortality risk for patients with PJI , with 5-year survival comparable to some common cancer diagnoses. (Source: The Knee)

The occurrence of Patellofemoral Pain Syndrome (PFPS) is often found in daily medical care. Rehabilitation is usually applied with good results.

Lateral radiograph in the prone position with the knee flexed at 15 ° (anterior gravity view (AGV)) is useful as a screening for anterior cruciate ligament (ACL) injuries, while it is sometimes difficult to find the side-to-side difference (SSD) in anterior tibial translation.

Extensive Proximal Extensor Mechanism Realignment for Chronic Patella Dislocations in Revision Knee Arthroplasty: Surgical Technique
Patella dislocation after primary or revision total knee arthroplasty (TKA) is a major challenge in revision surgery. In practice, the main reason for patella maltracking and instability following TKA is malrotation of the femoral and/or tibial components.

The condition of the contralateral knee may induce different degrees of knee extensor strength asymmetry and affect functionality in individuals with unilateral or bilateral osteoarthritis
Knee osteoarthritis (KOA) is a degenerative condition that limits joint function by altering muscle activation patterns and decreasing muscular strength [1]. Specifically, up to 30% less quadriceps strength may be registered at the involved side when compared with the contralateral side [2]. This limitation is likely to induce altered movement patterns and affect functionality [3]. However, findings on inter-limb strength asymmetries need to be interpreted with caution. KOA is a continuum of articular degeneration and may progress not only in the affected, but also in the contralateral limb. (Source: The Knee)
