The clinical importance of meniscal tears demonstrated by magnetic resonance imaging in osteoarthritis of the knee.
Meniscal tears are frequently found during magnetic resonance imaging of osteoarthritic knees. However, the prevalence and clinical relevance of these tears have not been determined. This study was designed to investigate the relationship between meniscal tears and osteoarthritis and between such tears and pain in patients with osteoarthritis. ⋯ Diagnostic study, Level I-1 (testing of previously developed diagnostic criteria in series of consecutive patients [with universally applied reference "gold" standard]). See p. 2 for complete description of levels of evidence.

Clinical outcomes after lumbar discectomy for sciatica: the effects of fragment type and anular competence.
The surgical treatment of sciatica with discectomy is ineffective in a sizable percentage of patients, and reherniation occurs after 5% to 15% of such procedures. The purpose of the present study was to determine if competence of the disc anulus and the type of herniation could be used to predict postoperative clinical outcomes following lumbar discectomy. ⋯ Prognostic study, Level I-1 (prospective study). See p. 2 for complete description of levels of evidence.

Open reduction and internal fixation of delayed unions and nonunions of fractures of the distal part of the humerus.
The purpose of the present retrospective study was to evaluate the results of open reduction and internal fixation of delayed unions and nonunions of fractures of the distal part of the humerus. ⋯ Therapeutic study, Level IV (case series [no, or historical, control group]). See p. 2 for complete description of levels of evidence.

Treatment of osteochondritis dissecans of the knee with autologous chondrocyte transplantation: results at two to ten years.
Osteochondritis dissecans of the knee is a challenging clinical problem. We previously reported on the early successful results of autologous chondrocyte transplantation for the treatment of focal cartilage defects. The purpose of the present study was to assess the intermediate to long-term results of this technique in a large group of patients with osteochondritis dissecans. ⋯ Treatment of osteochondritis dissecans lesions of the knee with autologous chondrocyte transplantation produces an integrated repair tissue with a successful clinical result in >90% of patients. We recommend the wider use of autologous chondrocyte transplantation for this condition.

Sustained spinal cord compression: part II: effect of methylprednisolone on regional blood flow and recovery of somatosensory evoked potentials.
The efficacy of methylprednisolone in the treatment of traumatic spinal cord injury is controversial. We examined the effect of methylprednisolone on regional spinal cord blood flow and attempted to determine whether recovery of electrophysiological function is dependent on reperfusion, either during sustained spinal cord compression or after decompression. ⋯ The methylprednisolone administered in this study did not provide a large or significant lasting benefit with regard to neurological preservation or restoration. Methylprednisolone may reduce regional spinal cord blood flow through mechanisms affecting normal autoregulatory blood-flow function.
