Purpose of the study: The objective of this retrospective analysis was to examine the functional and radiographic results of 33 resvisions for femoral implants using a long locked stem inserted without cement and coated with hydroxyapatite.

Material and methods: Mean follow-up was two years for 33 patient who underwent revison total hip arthroplasty (rTHA) with implantation of a press-fit long locked hydroxyapatite coated femoral stem (Aura or Linea) between 2000 and 2004. The explanted prosthesis was cemented in 23 cases. The reason for revision was femoral loosentng for 60%, femoral fracture for five pateints, and infection for two. According to the SOFCOT 1999 criteria, ten patients had bone defects score grade III or IV. Femorotomy was performed in 21 cases. Patients were reviewed clinically and radiologically. Function was assessed with the Postel-Merle-d’Aubligné (PMA) score and radiographic analysis determined the quality of osteointegration of the implants and the restitution of bone stock.

Results: There were six early complications (one death, one disloction with sciatic paralysis), and six late complications, mainly related to defective locking. The PMA score was less than 3 for only three patients. Twenty-six patients were satisfied or very satisfied and seven patients reported thigh pain which was generally moderate. The locking was released for five prostheses because of failure or pain (relief observed in three cases). Migration was noted in three cases, illustrating their non-integration. For 15 patients, corticalisation around the lower part of the prosthesis suggested implant mobility. This image was observed in all patients who complained of thigh pain (p=0.057). There was a significant increase in the cortical index, reflecting progression of the bone stock favoring the internal cortex.

Conclusion: This type of implant has provided a solution for the difficult problems of explantation and reimplantation of THA. These prostheses provide satisfactory short-term results and a significant improvement in bone stock. There remains the problem of osteointegration of certain implants. Technical factors can contribute to improved clinical results.

Purpose of the study: The purpose of this retrospective study was to analyze outome at more than one year of 33 anterior cruciate ligament (ACL) ligmanetoplasties performed in subjects aged over 50 years.

Material and methods: Between 1997 and 2002, arthroscopic ACL ligmantoplasty with a free graft was performed for 33 patients aged 50–67 years (mean 55.2 years). All patients were reviewed clinically and radiologically at least one year after surgery (mean follow-up 31 months, range 12–60 months). IKDC criteria and manual KT-1000 measurements were recorded. All subjects were classified C or D before the operation (IKCD 93 criteria). Plain x-rays were considered normal for 21 patients (63.5%) and eight (24%) presented remodeling of the medial femorotibial compartment or the intercondylar eminences. Four knees (12.5%) presented an asymptomatic narrowing of the medial femorotibial space (< 50%). In all patients, the indication for surgery was instability for daily life and/or sports activities, even for patients presenting an asymptomatic narrowing. An inter-articular patellar tendon graft, using two independent tunnels was performed for 29 patients. A hamstring plasty was performed for the others. Mean time from injury to surgery was 18 months. There were 15 lesions of the medial meniscus (45.5%). Six lesions were not repaired because they were considered stable. The lateral meniscus was involved less often (n=11 lesions). The lateral meniscal stock was preserved in nine knees. The rehabilitation protocol was the same as used for ligamentoplasty in young sportive patients.

Results: There were no intraoperative complications. Supplementary fixation of the tibia was required for three knees. All patients resumed their sports activities at the same level. The overall IKDS score was A for eight patients, B for 19 and C for six. For the patients in class C, the poor IKDC score resulted from persistent pain, generally present before the operation. Joint motion was preserved in 30 patients. IKDC laxity was A or B in all patients. At last follow-up, there was no radiological worsening and no meniscal injury left unrepaired required secondary treatment.

Conclusion: The operative technique was joint instability for daily life activities. Stability was improved in all patients, but the surgery did not improve pain relief. Age greater than 50 years is not a contraindication for arthroscopic reconstruction of the central pivot for chronic anterior instability. Fixation of the implant must be precise. The indication for surgery depends on the severity of the instability for daily life activities in a motivated patient.

Purpose: Pluridisciplinary therapeutic management is well defined for metastatic long bones. There are few prognostic criteria enabling an evidence-based choice between palliative surgery or abstention. We report a series of 24 metastatic femurs treated by palliative surgery and evaluated with the Tokuyashi score.

Material and methods: Sixteen women and eight men, mean age 71 years (5!-89) underwent centromedullary nailing of a metastatic femur (13/16 breast cancer in women, 20.24 other metastases. The Toskuhashi score was > 6 for 16/24 patients with pain unresponsive to morphine. Thirteen patients had fractured femurs and eleven had frail femurs due to the metastasis. Mean time to surgery was six days (1–15).

Results: A solid nail was used for four patients and a reconstruction nail for twenty. Operative time was 93 minutes (57–123). Blood loss was 200 l (150–350). There no intraoperative complications (fat embolus) excepting one tulip femur. Hospital stay was 23 days (8–55). Survival was 148 days (8–510) in patients with a frail metastatic tumour. Eight deaths occurred in patients with a fractured metastatic tumour (six within the first three postoperative weeks), two after preventive nailing. Weight bearing in living patients with a fractured femur was possible at 57 days (30–90). Only six patients required morphine in the early postoperative period. For the femurs with an isolated metastasis, the antalgesic effect of centromedullary nailing was significant (p< 0.05). There was a significant correlation between thee Tokuyashi score and mean survival. Mean survival in patients with a score < 3 was 2.1 months. Mean survival in patients with a score > 6 was 17 months.

Conclusion: Centromedullary nailing of the femur for metastatic fracture or fragilisation remains the treatment of choice for patients with short life expectancy. This technique limits pain while preserving independence as long as possible. The Tokuyashi score is correlated with patient survival. If this easy to establish score is too low (< 3), the survival can be expected to be insufficient for any surgical benefit.
