Comparative Study
Association between long-term quadriceps weakness and early walking muscle co-contraction after total knee arthroplasty.
Quadriceps weakness is one of the primary post-operative impairments that persist long term for patients after total knee arthroplasty (TKA). We hypothesized that early gait muscle recruitment patterns of the quadriceps and hamstrings with diminished knee performance at 3months after surgery would be related to long-term quadriceps strength at 1year after TKA. ⋯ III.

Different single-stage surgical approaches are currently under evaluation to repair focal cartilage lesions. This study aims to analyze the clinical and histological results after treatment of focal condylar articular lesions of the knee with microfracture and subsequent covering with a resorbable polyglycolic acid/hyaluronan (PGA -HA) matrix augmented with autologous bone marrow concentrate (BMC). ⋯ IV, case series.

Review Meta Analysis
Topical tranexamic acid in total knee replacement: a systematic review and meta-analysis.
To examine the safety and efficacy of topical use of tranexamic acid (TA) in total knee arthroplasty (TKA). ⋯ I, II.

Randomized Controlled Trial Comparative Study
Pain control after primary total knee replacement. A prospective randomised controlled trial of local infiltration versus single shot femoral nerve block.
We report a prospective blinded randomised trial of local infiltration versus femoral nerve block in patients undergoing primary total knee replacement (TKR), in accordance with the CONSORT statement 2010. ⋯ Intraoperative local infiltration gives superior pain relief compared to single shot femoral nerve block over the first 24h following primary TKR and minimises post-operative opiate use.

Comparative Study
Inflammatory predictors of ongoing pain 2 years following knee replacement surgery.
The prevalence of unrelieved pain following total knee arthroplasty (TKA) is substantial. ⋯ Prognosis study, Level 2.
