Long-term mortality and causes of death among patients with a total knee prosthesis in primary osteoarthritis.

Background: Short and midterm mortality of patients with osteoarthritis (OA) who have undergone total knee arthroplasty (TKA) is generally lower than that of the general population. Due to an increasing number of young patients who undergo TKA the expected lifetime of these patients is increasing. The purpose of this study was to assess the causes of death and long-term mortality among Finnish TKA patients.

Objective: To assess the risk of cancer associated with modern primary metal-on-metal hip replacements.

Design: Population based study.

Setting: Nationwide retrospective comparative register.

Surgical Technique for Treating Acute Ruptures of the Lateral Ligament Complex of the Ankle.

Introduction: Surgical treatment of an acute lateral ligament rupture is occasionally warranted.

Step 1 Incision: Make a skin incision from the anterior aspect of the fibula and curve it inferiorly and posteriorly.

Step 2 Repair: Repair the ligaments with absorbable sutures; if there is bone avulsion, pass the sutures through drill holes or use a suture anchor.

Patellofemoral osteoarthritis in patients with operative treatment for patellar dislocation: a magnetic resonance-based analysis.

Purpose: the clinical role of patellofemoral (PF) osteoarthrosis (OA) in the outcome after PF stabilizing surgery is poorly understood. The study hypothesis was that PF cartilage lesions and OA are associated with a poor long-term outcome after PF stabilizing surgery.

Methods: the study cohort included thirty-seven patients who underwent PF stabilizing surgery by traditional nonanatomic procedures and were evaluated a minimum of 10 years (range 10-21) after surgery.

Long-term outcome after surgical treatment of unresolved osgood-schlatter disease in young men: surgical technique.

Background: Surgical treatment of Osgood-Schlatter disease is occasionally warranted, but its long-term prognosis remains poorly investigated. We studied the rate of occurrence of surgical treatment of unresolved Osgood-Schlatter disease as well as the clinical course, radiographic characteristics, and long-term outcomes after that treatment in a large population of military recruits.

Methods: During a thirteen-year period, 178 consecutive recruits underwent surgery for unresolved Osgood-Schlatter disease, and 107 of them (117 knees) who met the inclusion criteria participated in a follow-up examination.

Surgical versus functional treatment for acute ruptures of the lateral ligament complex of the ankle in young men: a randomized controlled trial.

Background: Some have recommended surgical treatment of Grade-III lateral ligament injuries in very active individuals with high functional demands on the ankle. The purpose of this study was to establish whether surgery provides better long-term results than functional treatment for acute ruptures of the lateral ligaments of the ankle.

Methods: Physically active Finnish men (mean age, 20.

A retrospective comparative study of mortality and causes of death among patients with metal-on-metal and metal-on-polyethylene total hip prostheses in primary osteoarthritis after a long-term follow-up.

Background: All patients with total hip arthroplasty (THA), especially those with metal-on-metal (MM) THA, are exposed to metallic particles and ions, which may cause total or site-specific mortality. We analyzed the causes of total and site-specific mortality among a cohort of patients with MM and with metal-on-polyethylene (MP) THA after a long follow-up time.

Methods: Standardized mortality ratios (SMR) of total and site-specific causes of death were calculated for 579 patients with MM (McKee-Farrar) and 1585 patients with MP (Brunswik, Lubinus) THA for primary osteoarthritis.

Cancer risk is not increased after conventional hip arthroplasty.

Background And Purpose: Wear debris from conventional total hip arthroplasty (THA) induces chromosomal aberrations and DNA damage, which may promote cancerogenesis. A long latent period is required for solid tumors. We therefore re-analyzed a large THA cohort for cancer.

Long-term outcome after surgical treatment of unresolved Osgood-Schlatter disease in young men.

Background: Surgical treatment of Osgood-Schlatter disease is occasionally warranted, but its long-term prognosis remains poorly investigated. We studied the rate of occurrence of surgical treatment of unresolved Osgood-Schlatter disease as well as the clinical course, radiographic characteristics, and long-term outcomes after that treatment in a large population of military recruits.

Methods: During a thirteen-year period, 178 consecutive recruits underwent surgery for unresolved Osgood-Schlatter disease, and 107 of them (117 knees) who met the inclusion criteria participated in a follow-up examination.

Study Design: Cohort study; Level of evidence, 3.

Treatment with and without initial stabilizing surgery for primary traumatic patellar dislocation. A prospective randomized study.

Background: There is no consensus about the management of acute primary traumatic patellar dislocation in young physically active adults. The objective of this study was to compare the clinical outcomes after treatment with and without initial stabilizing surgery for primary traumatic patellar dislocation in young adults.

Methods: Forty young adults, thirty-seven men and three women with a median age of twenty years (range, nineteen to twenty-two years), who had an acute primary traumatic patellar dislocation were randomly allocated to be treated with initial surgical stabilization (eighteen patients, with each receiving one of two types of initial stabilizing procedures) or to be managed with an orthosis (twenty-two patients, including four who had osteochondral fragments removed arthroscopically).

A mini-invasive adductor magnus tendon transfer technique for medial patellofemoral ligament reconstruction: a technical note.

Patellar dislocations are associated with injuries to the medial patellofemoral ligament (MPFL). Several techniques for MPFL reconstruction have been recently published with some disadvantages involved, including large skin incisions and donor site morbidity. Arthroscopic stabilizing techniques carry the potential of inadequate restoration of MPFL function.

Incidence and trends of low back pain hospitalisation during military service--an analysis of 387,070 Finnish young males.

Background: There is evidence that low back pain (LBP) during young adulthood and military service predicts LBP later in life. The purpose of this study was to investigate the incidence and trends of LBP hospitalisation among Finnish military conscripts.

Methods: All male conscripts performing their compulsory military service during 1990-2002 were included in the study population.

Arthroscopic surgery for primary traumatic patellar dislocation: a prospective, nonrandomized study comparing patients treated with and without acute arthroscopic stabilization with a median 7-year follow-up.

Background: No data exist whether patients with primary traumatic patellar dislocation benefit from initial arthroscopic medial repair surgery.

Purpose: To compare long-term outcomes of patients treated with acute arthroscopic stabilization for patellar dislocation with those treated nonoperatively except for removal of loose bodies.

Study Design: Cohort study; Level of evidence, 2.

Ligament reconstruction versus distal realignment for patellar dislocation.

Unlabelled: Recently, medial patellofemoral ligament reconstruction has been emphasized for the treatment of patellar dislocation. This study compared the results of medial patellofemoral ligament reconstruction by adductor magnus tenodesis with distal patellar realignment in patients with recurrent patellar dislocation. Additionally, the development of patellofemoral osteoarthrosis was compared for these two procedures at a median 10-year followup.

Incidence and risk factors of acute traumatic primary patellar dislocation.

Purpose: The purpose of this study was to investigate incidence, nature, and risk factors of primary traumatic patellar dislocations.

Methods: We identified acute first-time traumatic patellar dislocations from a national hospital discharge register. Patients with previous patellar dislocations, subluxations, or knee traumas were excluded.

Long-term outcome of a transglenoid suture technique for anterior shoulder instability in young adults.

We reviewed the outcome of arthroscopic stabilisation of anterior glenohumeral instability in young adults using the transglenoid suture technique. A questionnaire was sent to 455 consecutive patients who had undergone this procedure between 1992 and 2000. Of these, 312 patients (68.

Elongated patellae at the final stage of Osgood-Schlatter disease: a radiographic study.

Aetiology of Osgood-Schlatter disease (OSD) is still unknown. Relative length of the patellar articular surface with the length of the patella, relative height of the tibial tubercle with the sagittal diameter of the tibia, Insall-Salvati, Blackburne-Peel, and Caton-Deschamps indexes, as well as Grelsamer-morphology type of the patella were measured from preoperative plain X-rays in 82 knees of 20-year-old males with OSD and in 87 knees of 20-year-old male controls with normal MRI findings of the knee. Seventy-eight of the OSD patients had separate ossicles.

Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults.

The incidence and long-term outcome of undisplaced fatigue fractures of the femoral neck treated conservatively were examined in Finnish military conscripts between 1970 and 1990. From 106 cases identified, 66 patients with 70 fractures were followed for a mean of 18.3 years (11 to 32).

Displaced femoral neck fatigue fractures in military recruits.

Background: Displaced fatigue fractures of the femoral neck are uncommon, but they can lead to substantial patient morbidity. This study was performed to examine the incidence, long-term consequences, radiographic findings, risk factors, and complications associated with this fracture.

Methods: Between 1975 and 1994, twenty-one military recruits sustained a displaced fatigue fracture of the femoral neck.

Cancer incidence and causes of death among total hip replacement patients: a review based on Nordic cohorts with a special emphasis on metal-on-metal bearings.

All patients with total hip arthroplasty (THA) are exposed to soluble or particulate forms of Co and Cr. Adverse effects of these wear products are not known. Data from Nordic registries is used to estimate adverse effects on a large scale, based mostly on metal-on-polyethylene bearings.

Malignant tumors at the site of total hip prosthesis. Analytic review of 46 cases.

During the years 1974 to 2003, a total of 46 cases of malignant tumors at the site of total hip arthroplasty, 41 sarcomas, 4 lymphomas, and 1 epidermoid carcinoma, have been reported in the Western literature. Soft tissue sarcomas occurred in 31 and bone sarcomas in 10 cases. Malignant fibrous histiocytoma was the most common in 20 (65%) of all soft tissue sarcomas.

Narrowing of lumbar spinal canal predicts chronic low back pain more accurately than intervertebral disc degeneration: a magnetic resonance imaging study in young Finnish male conscripts.

The objective of this magnetic resonance imaging study was to evaluate the role of degenerative changes, developmental spinal stenosis, and compression of spinal nerve roots in chronic low back (CLBP) and radicular pain in Finnish conscripts. The degree of degeneration, protrusion, and herniation of the intervertebral discs and stenosis of the nerve root canals was evaluated, and the midsagittal diameter and cross-sectional area of the lumbar vertebrae canal were measured in 108 conscripts with CLBP and 90 asymptomatic controls. The midsagittal diameters at L1-L4 levels were significantly smaller in the patients with CLBP than in the controls.
