..Published outcomes of revision ACL reconstruction have been worse than for primary ACL reconstruction. The preoperative evaluation, surgical techniques, and clinical outcomes of revision ACL reconstruction are reviewed...

..This manuscript summarizes the Kappa Delta Ann Doner Vaughan Award paper and presentation at the 2012 ORS/AAOS Annual Meeting...

....

..TE could promote repair of torn meniscus and/or replacement of meniscus loss because meniscus tear is a proven predictor of clinically relevant outcomes (such as osteoarthritis) in patients and is amenable to a potential TE solution...

..With numbers available, failure rates were not significantly different between groups. These findings suggest that graft type may not be the primary determinant for successful outcomes after anterior cruciate ligament surgery...

..The predictors of anterior cruciate ligament reconstruction (ACLR) outcome at 6 years as measured by validated patient-based outcome instruments are unknown...

..Suggestions regarding weight control and future education may improve intermediate-term outcomes...

..To determine the feasibility of using diffusion tensor MRI (DT-MRI) -based muscle fiber tracking to create biomechanical models of the quadriceps mechanism in healthy subjects and those with chronic lateral patellar dislocation (LPD)...

..Unfortunately, there is no widely accepted code of sports medicine ethics that adequately addresses these issues...

..This systematic review and meta-analysis investigated whether the short-term clinical outcomes of anterior cruciate reconstruction with allograft were significantly different from those with autograft...

..Large randomized clinical trials are needed to further delineate the role of these and other drugs and their effects on fracture healing...

..Increased knee pain at the time of anterior cruciate ligament reconstruction may potentially predict more difficult rehabilitation, prolonged recovery, and/or be predictive of increased knee pain at 2 years...

..Six classification systems have been proposed for describing rotator cuff tears designed to help understand their natural history and make treatment decisions...

..This study suggests the mechanical stiffness, but not the load at failure, of ligament scar can be significantly altered by the administration of TGF-beta 2...

..Overall, these studies show similar outcomes comparing the all-endoscopic and rear-entry anterior cruciate ligament reconstruction techniques...

..If such intraarticular injuries prove to be a significant risk factor for poor long-term outcome, women may enjoy a better prognosis after reconstruction...

..CLINICAL RELEVANCE: The use of fresh allograft tissue to treat osteochondral defects eliminates morbidity associated with harvesting autograft tissue without compromising the results of the surgical procedure...

..Surgeons should investigate and consider the characteristics of these cohorts when applying knowledge gleaned from these groups to their own patient populations...

..These findings emphasize the importance of further research on delineating the effect of platelets in treating of ACL injuries...

..LEVEL OF EVIDENCE: Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence...

..Meniscus tears in athletes display a variety of clinical presentations. Three different case scenarios are presented along with diagnoses and treatment options, and the best available evidence, at present, is reviewed...

..The outcome of anterior cruciate ligament (ACL) reconstruction is variable, and many patients have increased joint laxity postoperatively...

..Meniscal repair resulted in inconsistent findings. Virtually all patients who underwent complete meniscectomy at the time of ACL reconstruction had radiographic evidence of osteoarthritis at follow-up...

..We hypothesize that athletes possibly could reduce risk of certain IA pathologies with maintenance of lower body weight and BMI and thus potentially improve long-term functional outcomes after ACL reconstruction...

..However, ice was more effective yet resulted in higher pain scores. The authors hypothesize that IA temperatures below a threshold are associated with increased perceived pain...

..Additional studies defining the changes in laxity with cyclic loading and in vivo healing are indicated...

..The authors hypothesize that the inability to bury the longer screw length into the bone tunnel is associated with postoperative complications associated with the CALAXO screw...

..The decision to fix versus excise the loose body is controversial. Published operative fixation outcomes are small case series with short follow-up...

..We concluded that intra-articular corticosteroids reduce knee pain for at least 1 week and that intra-articular corticosteroid injection is a short-term treatment of a chronic problem...

..Combined analysis of these four studies shows that corticosteroid injections are effective in 57% of patients...

..CLINICAL RELEVANCE: This simple method is easily reproduced, can confirm accurate placement, and can eliminate extra-articular injection as the reason for clinical response failure...

..Its basis is the scientific method. The practicing clinician need understand only a few simple concepts to use this approach, and in doing so will provide the best available care to the patients...

..The purpose of this study was to evaluate the accuracy of radiographic measurements of the intercondylar notch...

..This systematic review of the available literature indicates that there is little reproducible evidence to support the efficacy of subacromial corticosteroid injection in managing rotator cuff disease...

..The purpose of this article is to provide the clinician an evidence/experience-based algorithm for the management of stress fractures...

..02). Placement of a collagen-PRP bridging scaffold in a central ACL defect can stimulate healing of the ACL histologically and biomechanically...

..The validity of the classification of such injuries is critical for prospective multicenter studies. The agreement among multiple surgeons at different institutions for articular cartilage lesions has not been established...

..Thus, when selecting an animal model for testing of these new treatment methods, it is important to select a model that has similar cellular distributions to that of the normal human anterior cruciate ligament...

....

..This study supports the hypothesis that premature scaffold failure may play a key role in the normally expected failure of the ACL to heal after injury...

....

..Clinicians have hypothesized that the opposite normal knee is at equal or increased risk compared with the risk of anterior cruciate ligament graft rupture in the operated knee...

..ACL/LCL injuries had fewer meniscal injuries. Multiligament-injured knees showed increased risk of a torn medial meniscus as chronicity increased. LEVEL OF EVIDENCE: Level IV...

..Systematic reviews conducted in this fashion can be used as a higher form of current concepts or as review articles and replace the traditional expert opinion narrative review...

..There are no studies investigating the reproducibility of arthroscopic classification of meniscal pathology among multiple surgeons at different institutions...

..Oral contraceptive use diminished the significant association between anterior cruciate ligament tear distribution and the ovulatory phase...

..Although successful at restoring near normal laxity to the knee in the short term, anterior cruciate ligament reconstructions have not been shown to prevent the development of posttraumatic arthritis...

..Further studies to determine the long-term effect of primary repair enhancement are needed...

..Topics discussed in this part of the article include continuous passive motion, early weight bearing in motion, postoperative bracing, and home-based rehabilitation...

..This part of the article discusses open versus closed kinetic chain exercises, neuromuscular electrical stimulation, accelerated rehabilitation, and miscellaneous topics...

..Once the predictors for good and poor outcomes are identified, surgeons and patients can be educated to the potential modifiable variables that improve patient's outcomes. ..
