February 2019 Primary Care Sports Medicine Journal Roundup

The American Journal of Sports Medicine (Feb 2019)

Lee, D. W., Kim, J. G., Cho, S. I., & Kim, D. H. (2019). Clinical Outcomes of Isolated Revision Anterior Cruciate Ligament Reconstruction or in Combination With Anatomic Anterolateral Ligament Reconstruction. The American Journal of Sports Medicine, 47(2), 324–333

  • Revision ACLR in combination with ALL reconstruction significantly reduced rotational laxity and showed a higher rate of return to the same level of sports activity than revision ACLR alone

Wang, D., Lin, K. M., Burge, A. J., et al (2019). Bone Marrow Aspirate Concentrate Does Not Improve Osseous Integration of Osteochondral Allografts for the Treatment of Chondral Defects in the Knee at 6 and 12 Months: A Comparative Magnetic Resonance Imaging Analysis. The American Journal of Sports Medicine, 47(2), 339–346.

  • Osteochondral allograft transplantation (OCA) augmented with bone marrow aspirate concentrate (BMAC) was not associated with improved osseous integration; decreased cystic changes; or other bone, cartilage, and ancillary feature changes compared with OCA alone

Martino, A. D., Matteo, B. D., Papio, T., et al (2019). Platelet-Rich Plasma Versus Hyaluronic Acid Injections for the Treatment of Knee Osteoarthritis: Results at 5 Years of a Double-Blind, Randomized Controlled Trial. The American Journal of Sports Medicine, 47(2), 347–354.

  • Both treatments were effective in improving knee functional status and symptoms over time. PRP did not provide an overall superior clinical improvement compared with HA in terms of either symptomatic-functional improvement at different follow-up points or effect duration.

Tanaka, K., Kanazawa, T., Gotoh, M., et al (2019). Effects of Estrogen-Deficient State on Rotator Cuff Healing. The American Journal of Sports Medicine, 47(2), 389–397.

  • The estrogen-deficient state by ovariectomy, compared with control rats, led to decreased biomechanical properties and poor development of chondroid tissue that influenced the repair of the tendon insertion after surgery.

  • Agents that modulate bone metabolism might improve tendon-to-bone healing in patients with an estrogen-deficient state, such as postmenopausal women who undergo rotator cuff surgery.

Saito, M., Utsunomiya, H., Hatakeyama, A., et al (2019). Hip Arthroscopic Management Can Improve Osteitis Pubis and Bone Marrow Edema in Competitive Soccer Players With Femoroacetabular Impingement. The American Journal of Sports Medicine, 47(2), 408–419.

  • Arthroscopic management for femoroacetabular impingement (FAI) provides favorable clinical outcomes, a high rate of return to sports, and, when present, resolution of pubic bone marrow edema (BME) among competitive soccer players

Oudelaar, B. W., Peerbooms, J. C., in ‘t, R. H., & Vochteloo, A. J. H. (2019). Concentrations of Blood Components in Commercial Platelet-Rich Plasma Separation Systems: A Review of the Literature. The American Journal of Sports Medicine, 47(2), 479–487

  • There is a large heterogeneity between PRP separation systems regarding concentrations of platelets, leukocytes, and growth factors in PRP.

  • As the ideal concentrations of blood components and growth factors for the specific fields of application are yet to be determined for most of the fields, future research should focus on which type of PRP is most suitable for the specific field.

Minkara, A. A., Westermann, R. W., Rosneck, J., & Sean Lynch, T. (2019). Systematic Review and Meta-analysis of Outcomes After Hip Arthroscopy in Femoroacetabular Impingement. The American Journal of Sports Medicine, 47(2), 488–500.

  • A high percentage of patients return to sport activities after hip arthroscopy for FAI, with a low rate of complications and reoperation. All patient-reported outcome measures, except for mental health, significantly improved after surgery.

British Journal of Sports Medicine (February 2019)

ening Programme prevents groin problems among male football players: a cluster-randomised controlled trial Br J Sports Med 2019;53:150-157.

  • The simple Adductor Strengthening Programme substantially reduced the self-reported prevalence and risk of groin problems in male football players.

Miyamoto GC, Lin CC, Cabral CMN, et al Cost-effectiveness of exercise therapy in the treatment of non-specific neck pain and low back pain: a systematic review with meta-analysis Br J Sports Med 2019;53:172-181.

  • Exercise therapy seems to be cost-effective compared with usual care for subacute and chronic low back pain.

  • Exercise therapy was not (more) cost-effective compared with other interventions for neck pain and low back pain. The cost-utility estimates are rather uncertain, indicating that more economic evaluations are needed.

Sports Medicine (February 2019)

Trommelen J, Betz MW, van Loon LJC. The Muscle Protein Synthetic Response to Meal Ingestion Following Resistance-Type Exercise. Sports Med. 2019 Feb;49(2):185-197. doi: 10.1007/s40279-019-01053-5. Review.

  • Nutritional recommendations to maximize the muscle protein synthetic response to exercise depend on the type of meal (e.g., protein supplements vs. mixed meals) and the time until the next feeding opportunity (e.g., feeding before overnight sleep) and, therefore, need to be personalized to the individual athlete

Goulet EDB, Hoffman MD. Impact of Ad Libitum Versus Programmed Drinking on Endurance Performance: A Systematic Review with Meta-Analysis. Sports Med. 2019 Feb;49(2):221-232. doi: 10.1007/s40279-018-01051-z. Review.

  • Exercise training elicits significant improvements in diastolic function and beneficial remodeling in T2DM and DCM animal models, but not necessarily improvements in systolic function and left ventricular structure, regardless of exercise type

Stutz J, Eiholzer R, Spengler CM. Effects of Evening Exercise on Sleep in Healthy Participants: A Systematic Review and Meta-Analysis. Sports Med. 2019 Feb;49(2):269-287.

  • Evening exercise improved REM, slow wave sleep.

  • Just dont exercise right before bed, sleep-onset latency, total sleep time, and sleep efficiency might be impaired after vigorous exercise ending ≤ 1 h before bedtime
