The disproportionate increase in total knee replacements among younger patients may be a result of a growing number of knee injuries and expanding indications for the procedure. CLINICAL RELEVANCE: The dramatic increase in total knee replacement utilization has implications for manpower, health-care financing, and the clinical management of patients who have advanced osteoarthritis of the knee.

However, osteopenia does develop in the injured limb during cast immobilization for fracture treatment. Further investigation is required to determine if the bone mineral mass will return to normal or if a permanent decrease is to be expected, which may constitute a hypothetical risk of sustaining a second fracture.

Shorter, more highly convex articulating surfaces may be inherently less stable with regard to anterior tibial translation and rotation. These findings may partially explain the greater overall predisposition of women compared with men toward ACL injury as well as why some studies have demonstrated no sex differences in graft reinjury after ACL reconstruction.

One hundred and twenty consecutive nonselected total hip arthroplasties were performed in 108 patients with use of a cementless acetabular component. This series was evaluated at a minimum of twenty years of follow-up and was compared with 330 consecutive hip arthroplasties that had been performed by the same surgeon with use of cemented acetabular components and had been followed for a comparable period of time.

Adolescent males are at highest risk for dislocation. Nearly half of acute elbow dislocations occurred in sports, with males at highest risk with football, and females at risk with gymnastics and skating activities.

The center of the ACL femoral footprint and the popliteus insertion are easily identifiable landmarks and will allow safe, reproducible, anatomic ACL reconstruction in the skeletally immature patient.

Recent litigation experiences and longer duration of orthopaedic practice were independent predictors of an increased use of defensive practices in ordering imaging studies. This real-time audit showed that a large proportion of MRI studies were ordered for primarily defensive medicine reasons.

In some shoulders, use of a keel or pegs to provide fixation of a polyethylene component in the absence of good support from subchondral bone may not be sufficient to resist compressive and eccentric forces, resulting in loosening. Preserving subchondral bone may be important for long-term longevity of the glenoid component. LEVEL OF EVIDENCE: Therapeutic Level III.

The purpose of the present report is to update that study and to report the outcome beyond twenty years. The patients were followed prospectively with clinical assessment with use of the Harris hip score and radiographic analysis, and the results were collected in a database. Two hundred and sixty-eight hips were functioning at the time of death or at the time of the latest follow-up. A total of forty-three hips (14%) underwent major revision for all causes, and an additional four hips underwent minor revision. At a mean of twenty-three years...

Changes in the cultural experiences in programs that have not trained female orthopaedic surgeons, such as an increased number of female faculty, and policies that emphasize diversity may provide a greater opportunity for our orthopaedic profession to attract female medical students.

Failure of fracture-healing was associated with a decreased expression of BMP-2 and 4 and a disturbed ratio of angiogenic to osteogenic growth factors, which may be responsible for nonunion. CLINICAL RELEVANCE: Because the intrinsic angiogenic response during nonunion formation was sufficient for adequate vascularization, treatment strategies for nonunions should focus on the stimulation of osteogenesis rather than on the stimulation of angiogenesis.

Distinguishing the superficial bundles of the articularis genus from the vastus intermedius on MRI can be difficult. CLINICAL RELEVANCE: Given its relationship to the anterior aspect of the knee joint and its association with the suprapatellar bursa, the articularis genus may be a neglected cause of undifferentiated anterior knee pain.

CLINICAL RELEVANCE: Compared with hemiarthroplasty, humeral resurfacing may limit eccentric glenoid wear and permit better function because the glenohumeral joint biomechanics and the moment arms of the rotator cuff and the deltoid muscle are restored more closely to those of the intact condition.

Newer techniques such as MaioRegen implantation and the "one-step" transplantation technique are based on different rationales; the first relies on the characteristics of the scaffold and the second on the regenerative potential of mesenchymal cells. Both of these newer procedures have the advantage of being minimally invasive and requiring a single operation. PMID: 22218387 [PubMed - in process] (Source: The Journal of Bone and Joint Surgery.

The patient did well initially but now has recurrent medial joint-line pain in the knee, which developed when he planted the right leg to throw a pass during summer training camp. He was evaluated by the team's athletic trainer and by an orthopaedic surgeon, both of whom, on the basis of their physical examination of the boy, believe that he may have sustained a recurrent meniscal tear.

There was a strong association between pseudotumor and the high levels of wear debris that are generated during edge-loading. However, not all patients with high wear developed pseudotumors, and not all pseudotumors had high wear; therefore, other factors are most likely involved in the cause of pseudotumors.

CLINICAL RELEVANCE: This study provides a novel approach that may have potential to diminish the irreparable structural and functional changes of the musculotendinous unit associated with chronic rotator cuff tear, but complications of anabolic steroid use also need to be considered. ...

Surgeons and families should be aware that use of a walking hip spica cast rather than a traditional hip spica cast may be associated with a greater likelihood that wedge adjustment of the cast will be necessary to treat fracture malalignment.

Silicate substitution significantly increased the amount of bone that formed and the amount of bone attached to the implant surface. New bone formation occurred through an intramembranous process within the implant structure. CLINICAL RELEVANCE: The use of a silicate-substituted calcium phosphate material instead of stoichiometric calcium phosphate ceramic during orthopaedic surgery may substantially augment repair and regeneration of bone.

In the majority of patients, this was a consequence of the correction of a fixed equinus contracture of the ankle plantar flexors that was constraining preexisting ankle dorsiflexor function. Weakness of all of the muscles is common, and surgical lengthening should only be considered for the correction of recalcitrant muscle contractures. Improved function of the antagonist muscle should be anticipated and optimized by appropriately focused strength training and other modalities during rehabilitation.

Concerns have been raised regarding the effect of the work environment on the health of the female orthopaedic surgeon and her fetus or neonate. Occupational risks, and specifically risks to the pregnant orthopaedic surgeon, are becoming an important issue in medicine. Such risks include exposure to methylmethacrylate (MMA), anesthetic gases, blood-borne pathogens, radiation, emotional stress, and physical stress. Awareness of and knowledge about such exposures are needed for the pregnant orthopaedic surgeon to make informed decisions about her occupational exposures and to be proactive about her own and ...

The higher reoperation rate was found in the group without acromioplasty. Further study that includes follow-up imaging and patient-reported outcomes over a greater follow-up period is needed.Level of Evidence: Therapeutic Level I.

The strongest clinical predictor of repeat surgery was a lumbar spine operation prior to the index operation. Arthrodeses were not significantly associated with lower rates of repeat surgery after the first postoperative year, and patients who had had complex arthrodeses had the highest rate of reoperations.Level of Evidence:Therapeutic Level III.

Infection was initially eradicated in twenty-three (82%) of twenty-eight patients, more than half of our patients had mild or no pain, and 43% of patients declined a second-stage procedure because of acceptable function and pain relief. Conversely, five of twenty-eight patients had severe pain and five patients had persistent infection requiring additional surgery. The use of the reverse total shoulder arthroplasty did not appear to improve outcomes.Level of Evidence:Therapeutic Level IV.

Postoperative fracture appears to be a common complication of this treatment and needs to be studied further. Treatment with curettage and high-speed burr alone may not reduce recurrence.Level of Evidence:Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Increasing patient volume, decreasing physician reimbursement, malpractice litigation, elevated stress, and growing job dissatisfaction have been implicated in disruptive behavior, which has emerged as one of the major challenges in health care. Because the aging patient population relies increasingly on orthopaedic services to maintain quality of life, improving professionalism and eradicating disruptive behavior are urgent concerns in orthopaedic surgery.

However, more tears and poorer synovial coverage were observed for posterolateral than for anteromedial bundles during second-look arthroscopy. No significant correlation was found between graft appearance and clinical outcome.Level of Evidence:Therapeutic Level IV.

Careful physical examination and magnetic resonance imaging (MRI) evaluation aid in achieving a timely diagnosis. Surgical reduction and suture fixation is safe and effective in restoring subscapularis function and return to sports, even in cases of delayed treatment. Full recovery of shoulder external rotation may not be seen until six months postoperatively.Level of Evidence:Therapeutic Level IV.

More importantly, the study demonstrated marked improvement in multiple, objective parameters of gait following total ankle arthroplasty as compared with the patient's own preoperative function. The long-term maintenance of the gait improvements will require further study.Level of Evidence:Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

Simple lifestyle changes such as dietary restriction, increased physical activity, and vitamin D supplementation may decrease muscle fat content and improve physical performance in the elderly.

Range of knee motion may reasonably be self-assessed by comparison with photographs. Long-term follow-up of patients after total knee arthroplasty may be possible with use of patient-reported measures, alleviating the burden of clinic visits yet maintaining contact, but further studies involving other validated instruments is warranted.
