There is a relative paucity of data regarding the effect of anterior cruciate ligament (ACL) reconstruction on the ability of American high school and collegiate football players to return to play at the same level of competition as before their injury or to progress to play at the next level of competition. ⋯ Return to play percentages for amateur American football players after ACL reconstruction are not as high as would be expected. While technical aspects of ACL reconstruction and the ensuing rehabilitation have been studied extensively, the psychological factors (primarily a fear of reinjury) influencing the ability to return to play after ACL surgery may be underestimated as a critical factor responsible for athletes not returning to play at any level of competition.

There is limited information on outcomes and return to play (RTP) after anterior cruciate ligament reconstruction (ACLR) in soccer athletes. ⋯ Younger and male soccer players are more likely to return to play after ACL reconstruction. Return to soccer after ACLR declines over time. ACLR on the nondominant limb potentially places the dominant limb at risk for future ACL injury.

Comparative Study
Arthroscopic rotator cuff repair using modified Mason-Allen medial row stitch: knotless versus knot-tying suture bridge technique.
When using a method of suture bridge technique, there may be a possibility of strangulation of the rotator cuff tendon at the medial row. The style of knots chosen to secure the medial row might conceivably be a factor to reduce this possibility. ⋯ In arthroscopic suture bridge repair of full-thickness rotator cuff tears, clinical results of both a knotless and a conventional knot-tying group showed improvement without significant difference between the 2 groups. However, the knotless group had a significantly lower retear rate compared with the conventional knot-tying group. A knotless suture bridge technique could be a new supplementary repair technique to conventional technique.

Some cross-sectional studies have suggested that the prevalence of low back pain (LBP) may be high among endurance athletes with repetitive back loading, but there are no large, prospective cohort studies addressing this issue. ⋯ Low back pain was not more common among former endurance athletes with specific back loading compared with non-athletes. The results indicate that years of prolonged and repetitive flexion or extension loading in endurance sports does not lead to more LBP. However, a large training volume in the past year and previous episodes with LBP are risk factors for LBP. Comparing the sports of rowing, cross-country skiing, and orienteering, it appears that whereas orienteering is protective, rowing can provoke LBP.

Osteochondral allografts (OCAs) are currently preserved at 4°C and used within 28 days of donor harvest. The window of opportunity for implantation is limited to 14 days due to a 2-week disease testing protocol. ⋯ Storage of OCAs in serum-free chemically defined media at 37°C can increase the "window of opportunity" for implantation of optimal tissue from 14 days to 42 days after disease testing clearance.
