Bone bruising, commonly found on magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) injury, may be associated with intra-articular injuries, but little is known about this association. ⋯ Bone bruising is more common and severe in young men, and lateral bone bruising is associated with lateral meniscal tears. Medial meniscal tears are associated with increased severity of LTP bruising.

Randomized Controlled Trial Comparative Study
CT and MRI measurements of tibial tubercle-trochlear groove distances are not equivalent in patients with patellar instability.
Tibial tubercle-trochlear groove distance (TT-TG) is a commonly used measurement for surgical decision making in patients with patellofemoral malalignment and instability. This measurement has historically been performed utilizing axial computed tomography (CT). More recently, magnetic resonance imaging (MRI) has been proposed as an equivalent method, but this has not yet been fully validated. ⋯ The TT-TG distance can be measured with excellent interrater reliability on both MRI and CT; however, the values derived from these 2 tests may not be interchangeable. This observation should be taken into consideration when MRI is used for surgical planning because MRI may underestimate the TT-TG distance when compared with CT.

Incidence of postoperative anterior cruciate ligament reconstruction infections: graft choice makes a difference.
Infections after anterior cruciate ligament reconstruction (ACLR) can be devastating. Hamstring tendon autografts may be more susceptible to infections than other graft types. ⋯ The overall SSI rate after ACLR was 0.48%. Deep SSIs were identified in 0.32% of the ACLR cases and superficial SSIs in 0.16%. An 8.2-times higher risk of SSIs was observed in hamstring tendon autografts compared with BPTB autografts. No difference in SSI incidence was identified between allografts and BPTB autografts. Surgeons should bear in mind that although the overall infection rates after ACLR are low, there is an increased risk of deep infections with hamstring tendon autografts.

Sexual dimorphism in humans has already been documented at different levels, and preliminary findings also suggest the importance of patient sex on clinical outcome in the treatment of cartilage lesions. ⋯ Women have a different knee chondral lesion pattern and more often have unfavorable conditions related to the cause of injury, site, and activity level, and they also have lower raw, not standardized, scores. However, a matched-pair analysis with data standardized for the specific patient categories showed that, on equal terms, women have the same possibilities for successful outcome as men after surgical treatment for knee cartilage regeneration.

Postoperative passive motion is the most widely accepted rehabilitation protocol after rotator cuff repair; however, a rotator cuff retear remains a frequent surgical complication. Clinical outcomes indicate that early passive motion is harmless to rotator cuff healing, but no laboratory evidence supports this proposition. ⋯ The results have an implication in supporting the rehabilitation protocol of early passive motion after rotator cuff repair.
