Good mid-term outcomes and low rates of residual rotatory laxity, complications and failures after revision anterior cruciate ligament reconstruction (ACL) and lateral extra-articular tenodesis (LET).
Residual rotational instability remains a controversial factor when analysing failure rates of anterior cruciate ligament (ACL) reconstruction. Anatomical and biomechanical studies have demonstrated a very important role of anterolateral structures for rotational control. Revision ACL is considered one of the main indications for a lateral extra-articular tenodesis (LET). Yet, few series evaluating these procedures are published. ⋯ IV.

ReviewQuadriceps tendon autograft ACL reconstruction has less pivot shift laxity and lower failure rates than hamstring tendon autografts.
Quadriceps tendon (QT) autograft ACL reconstruction was hypothesized to possess less anterior knee laxity, pivot shift laxity, and lower failure rates than hamstring tendon (HT) autografts. ⋯ Level IV.

Controlled Clinical TrialPrevention of severe knee injuries in men's elite football by implementing specific training modules.
Injury prevention of knee injuries by means of training and warm-up exercises has been investigated in several studies in amateur football. However, the number of investigations in elite football is limited despite the currently higher injury incidence of severe knee injuries. Therefore, the purpose of this study was to investigate whether specifically adapted preventive training modules may reduce severe knee injuries in elite football. ⋯ Appropriate preventive training modules reduce severe knee injuries in elite football significantly. The key for the sustainability of preventive training measures are programmes specifically adapted to the demands of the playing level and to the preferences of the coaches LEVEL OF EVIDENCE: II.

Good mid-term outcomes after adipose-derived culture-expanded mesenchymal stem cells implantation in knee focal cartilage defects.
The purpose of the present study was to investigate the mid-term outcomes of a single-stage cell-based procedure in patients with knee focal symptomatic cartilage defects using matrix-induced culture-expanded autologous AD-MSCs. It was hypothesised that the increased number of autologous AD-MSCs after culture expansion is a safe and efficient cartilage repair procedure, which improves overtime chondrogenesis in cartilage lesions METHODS: Twenty-five consecutive patients treated for a symptomatic cartilage defect were prospectively followed for 3 years. The median age of patients was 30.5 (range 16-43) with a median BMI of 23.6 kg/m2 (range 19-29) and an average size of the lesion of 3.5 cm2 (range 2-6). All patients underwent a single-stage procedure consisting in filling each defect with autologous culture-expanded mesenchymal stem cells embedded in a trimmed-to-fit commercially available biodegradable matrix. Pre-operative and post-operative evaluation included knee-related clinical and functional evaluation based on objective and subjective scores at 6, 12, 24 and 36 months and MRI evaluation of the repair tissue using the MOCART score at 12 and 24 months. ⋯ IV.

Randomized Controlled TrialEarly mobilization does not reduce the risk of deep venous thrombosis after Achilles tendon rupture: a randomized controlled trial.
The hypothesis was that early functional mobilization would reduce the incidence of deep venous thrombosis (DVT) during leg immobilization after Achilles tendon rupture surgery. A secondary aim was to evaluate if the amount of weightbearing and daily steps influenced the risk of sustaining a DVT. ⋯ Therapeutic, level 1.
