Minimum thickness of all-poly tibial component unicompartmental knee arthroplasty in patients younger than 60 years does not increase revision rate for aseptic loosening.
Management of unicompartmental knee osteoarthritis in middle-aged patients is a challenging problem. Despite its functional advantages, UKA still raises questions concerning implant survivorship and an increased revision risk for aseptic loosening mainly due to polyethylene wear. The main purpose of the present study was to investigate whether using the minimum thickness of an all-poly tibial UKA in patients under 60 years of age increases the revision rate for aseptic loosening. The secondary purposes were to compare implant survivorship with data reported in literature and to prospectively evaluate the clinical outcome in this selected group of patients. ⋯ The present study failed to demonstrate an increased revision rate for aseptic loosening of the implant in patients under 60 years of age, who received an all-poly tibial component UKA using the minimum thickness of the implant in all cases.

ReviewBicompartmental knee arthroplasty of the patellofemoral and medial compartments.
Studies have shown that after total knee arthroplasty neither normal biomechanics nor function is obtained. Selective resurfacing of diseased compartments could be a solution. A narrative review of the available literature on bicompartmental arthroplasty is presented. ⋯ Modular bicompartmental arthroplasty is an excellent alternative to treat bicompartmental arthritis of the knee leading to good functional results and superior biomechanics in well-selected patients. Caution is needed since only a few peer reviewed articles with small series and old implant designs are available on this type of arthritis treatment. Survivorship in these studies is inferior to total knee arthroplasty.

Randomized Controlled TrialLess blood loss under concomitant administration of tranexamic acid and indirect factor Xa inhibitor following total knee arthroplasty: a prospective randomized controlled trial.
The objective of this prospective randomized controlled trial was to assess the efficacy and safety of simultaneous application of tranexamic acid and indirect factor Xa inhibitor following total knee arthroplasty (TKA). ⋯ The use of tranexamic acid could reduce acute blood loss significantly without any adverse effect resulted from drug interaction with concomitant use of indirect factor Xa inhibitor following TKA. Therefore, simple combination of these drugs can be recommended to reduce post-operative blood loss as well as to reduce DVT following TKA.

The treatment of acquired patella baja with proximalize the tibial tuberosity.
Acquired patella baja may result in decreased range of motion of the knee, extensor lag, and anterior knee pain. The aim of the study was to evaluate the efficacy of tibial tubercle osteotomy with proximal displacement. ⋯ A series of patients with patella baja, treated with proximalization of the tibial tuberosity, achieved satisfactory outcomes in terms of pain relief and improved function, without major complication.

Patient satisfaction after total knee arthroplasty is affected by their general physical well-being.
We hypothesise that patients with a worse post-operative generic physical health, and those with a subclinical improvement, will have a greater rate of dissatisfaction with their total knee arthroplasty (TKA) despite improvement in their knee function. ⋯ Despite benefitting from a significant improvement in their OKS after TKA, patients with a poor post-operative SF-12 PCS and those with a subclinical improvement in their general physical well-being are significantly less likely to be satisfied at 1 year.
