Meniscus allograft transplantation (MAT) has shown efficacy in relieving pain and improving knee joint function, but objective evaluation in a large number of patients is necessary to verify this effect. ⋯ Meniscus allograft transplantation using bone fixation resulted in significant symptomatic and functional improvements. Magnetic resonance imaging or second-look arthroscopy was necessary to assess allograft status even after favorable clinical outcome. Meniscus allograft transplantation with bone fixation is considered effective for symptomatic, totally meniscectomized knees.

Fresh-stored osteochondral allografts have been used successfully to resurface large chondral and osteochondral defects of the knee. However, there are limited data available for the return to athletic activity. ⋯ Osteochondral allograft transplantation in an athletic population for chondral and osteochondral defects in the knee allows for a high rate of return to sport. Risk factors for not returning to sport included age ≥25 years and preoperative duration of symptoms ≥12 months.

Review Comparative Study
Does double-row rotator cuff repair improve functional outcome of patients compared with single-row technique? A systematic review.
The advantage of single-row versus double-row arthroscopic rotator cuff repair techniques has been a controversial issue in sports medicine and shoulder surgery. There is biomechanical evidence that double-row techniques are superior to single-row techniques; however, there is no clinical evidence that the double-row technique provides an improved functional outcome. ⋯ Through a comprehensive literature search and meta-analysis of current arthroscopic rotator cuff repairs, we found that the single-row repairs did not differ from the double-row repairs in functional outcome scores. The double-row repairs revealed a trend toward a lower radiographic proven retear rate, although the data did not reach statistical significance. There may be a concerning trend toward higher retear rates in patients undergoing a single-row repair, but further studies are required.

Platelet-rich plasma (PRP) contains various growth factors and appears to have a potential to promote tendon healing, but evidence is lacking regarding its effect on human tenocytes from rotator cuff tendons with degenerative tears. ⋯ These findings suggest that PRP might be used as a useful biological tool for regenerative healing of rotator cuff tears by enhancing the proliferation and matrix synthesis of tenocytes from tendons with degenerative tears.

Injuries to the anterior cruciate ligament (ACL) are common in athletic populations, particularly in athletes participating in football, soccer, and skiing. ⋯ Between 2004 and 2009, NCAA football players experienced a greater number of ACL injuries in games compared with practices, in scrimmages compared with regular practices, and when playing on artificial turf surfaces. This latter finding will need to be confirmed by additional studies.
