Comparative Study
Comparison of partial versus complete arthroscopic repair of massive rotator cuff tears.
Complete repair of massive rotator cuff tears can be limited by tendon retraction and poor tissue quality. When a complete repair cannot be accomplished, a significant partial repair may be possible. ⋯ Partial repair of massive rotator cuff tears yielded outcomes comparable with complete repair of massive tears.

In patients with patellar instability, a pathological tibial tubercle-trochlear groove (TT-TG) distance is a risk factor. However, the TT-TG distance gives no information about the location of the malformation. ⋯ Only 57% of the patients with a pathological TT-TG distance (≥20 mm) had lateralization of the tibial tubercle in relation to the posterior cruciate ligament. The TT-PCL distance is an alternative method for determining the position of the tibial tubercle.

Comparative Study
Stability of double-row rotator cuff repair is not adversely affected by scaffold interposition between tendon and bone.
Rotator cuff reconstructions may be improved by adding growth factors, cells, or other biologic factors into the repair zone. This usually requires a biological carrier (scaffold) to be integrated into the construct and placed in the area of tendon-to-bone healing. This needs to be done without affecting the constructs mechanics. Hypothesis/ ⋯ Scaffolds intended for application of growth factors or cellular components in a repair situation did not adversely jeopardize the stability of the operative construct.

Randomized Controlled Trial
Is early passive motion exercise necessary after arthroscopic rotator cuff repair?
Early passive motion exercise has been the standard rehabilitation protocol after rotator cuff repair for preventing postoperative stiffness. However, recent approaches show that longer immobilization may enhance tendon healing and quality. ⋯ Early passive motion exercise after arthroscopic cuff repair did not guarantee early gain of ROM or pain relief but also did not negatively affect cuff healing. We suggest that early passive motion exercise is not mandatory after arthroscopic repair of small to medium-sized full-thickness rotator cuff tears, and postoperative rehabilitation can be modified to ensure patient compliance.

The administration of amide-type local anesthetics to cartilaginous tissues has revealed potential chondrotoxicity. ⋯ Single-dose injections of 1% lidocaine may be significantly chondrotoxic, and further investigation regarding in vivo chondrotoxicity appears warranted.
