One-step surgery with multipotent stem cells and Hyaluronan-based scaffold for the treatment of full-thickness chondral defects of the knee in patients older than 45 years.
The aim of this study is to prospectively evaluate the medium-term effectiveness and regenerative capability of autologous adult mesenchymal stem cells, harvested as bone marrow aspirate concentrate (BMAC), along with a hyaluronan-based scaffold (Hyalofast) in the treatment of ICRS grade 4 chondral lesions of the knee joint, in patients older than 45 years. ⋯ Prospective cohort study, Level II.

Collagen application reduces complication rates of mid-substance ACL tears treated with dynamic intraligamentary stabilization.
Dynamic intraligamentary stabilization was recently proposed as an option for the treatment of acute ACL ruptures. The aim of this study was to investigate the feasibility of the procedure in mid-substance ACL ruptures and examine whether the additional application of a bilayer collagen I/III membrane would provide for a superior outcome. ⋯ Case control study, Level III.

Reconstruction of chronic patellar tendon rupture with contralateral bone-tendon-bone autograft.
To evaluate the clinical and functional outcome following the reconstruction of chronic patellar tendon ruptures using the contralateral bone-tendon-bone (BTB) autograft. ⋯ In this limited cohort, surgical reconstruction of chronic patellar tendon ruptures using contralateral bone-tendon-bone graft was a safe and viable option that improves clinical and functional outcomes compared to presurgical function. However, despite the restoration of a normal patellar height, function did not return to preinjury level.

Posterolateral portal tibial tunnel drilling for posterior cruciate ligament reconstruction: technique and evaluation of safety and tunnel position.
To evaluate the safety for neurovascular structures and accuracy for tunnel placement of the posterolateral portal tibial tunnel drilling technique in posterior cruciate ligament (PCL) reconstruction. ⋯ The posterolateral portal tibial tunnel technique is safe relative to neurovascular structures and creates an anatomically appropriate tibial tunnel location. The clinical relevance of study is that this technique may be safely and accurately used in PCL reconstruction to decrease the risk of neurovascular damage (avoid use of a posteriorly directed pin), avoid the use of intraoperative fluoroscopy, and avoid the sharp turn during graft passage.

Randomized Controlled TrialEffects of arthroscopy-guided suprascapular nerve block combined with ultrasound-guided interscalene brachial plexus block for arthroscopic rotator cuff repair: a randomized controlled trial.
The aim of this study was to compare the pain relieving effect of ultrasound-guided interscalene brachial plexus block (ISB) combined with arthroscopy-guided suprascapular nerve block (SSNB) with that of ultrasound-guided ISB alone within the first 48 h after arthroscopic rotator cuff repair. ⋯ Randomized controlled trial, Level I. ClinicalTrials.gov Identifier: NCT02424630.
