Intra-articular injection of adipose-derived stem cells (ASCs) has shown promise for improving symptoms and cartilage quality in the treatment of osteoarthritis (OA). However, while most preclinical studies have been performed with plastic-adherent ASCs, most clinical trials are being conducted with the stromal vascular fraction (SVF), prepared from adipose tissue without prior culture. ⋯ It was observed that both ASCs and SVF resulted in clinical improvement in patients with knee OA, but that ASCs outperform SVF in the early reduction of symptoms and pain with less comorbidity.

Ulnar collateral ligament (UCL) reconstruction is commonly performed among overhead throwing athletes. Previous studies demonstrated relatively high rates of return to sport after primary reconstruction. Outcomes after revision UCL reconstruction have not been widely studied. ⋯ This systematic review demonstrated a limited rate of return to preinjury level of sport among elite-level baseball players who underwent revision UCL reconstruction. Pitching durability and career longevity were inferior to results that were reported for players who underwent primary UCL reconstruction alone. This study suggests that outcomes after revision UCL reconstruction are not reliable and elite-level players should be counseled accordingly.

There is a paucity of literature regarding risk factors and mechanisms of Achilles tendon (AT) ruptures in the National Basketball Association (NBA). ⋯ In the NBA, a majority of AT ruptures occur early in the season, in veteran players, with almost half not returning to play or starting fewer than 10 games in the remainder of their career. The most common mechanism of injury is taking off from a stopped position just before toe-off in a dorsiflexed foot.

Randomized Controlled Trial Comparative Study
Complex Tears, Extrusion, and Larger Excision Are Prognostic Factors for Worse Outcomes 1 and 2 Years After Arthroscopic Partial Meniscectomy for Degenerative Meniscal Tears: A Secondary Explorative Study of the Surgically Treated Group From the Odense-Oslo Meniscectomy Versus Exercise (OMEX) Trial.
Few studies have examined morphological findings from preoperative magnetic resonance imaging (MRI) and arthroscopic findings as prognostic factors for outcomes 1 and 2 years after arthroscopic partial meniscectomy (APM). ⋯ NCT01002794 (ClinicalTrials.gov identifier).

There is controversy about the benefit of arthroscopic partial meniscectomy (APM) for degenerative lesions in middle-aged patients. ⋯ There were no meaningful differences in patient satisfaction or clinical outcomes between patients with traumatic and degenerative tears and no or mild OA. Predictors of dissatisfaction with APM were female sex, obesity, and lateral meniscal tears. Our findings suggested that APM was an effective medium-term option to relieve pain and recover function in middle-aged patients with degenerative meniscal tears, without obvious OA, and with failed prior physical therapy.
