Anterior cruciate ligament reconstruction: outcome using a patellar tendon bone (PTB) autograft (one bone block technique).

OBJECTIVE: The aim of this study was to determine the outcome of anterior cruciate ligament (ACL) reconstruction using a patellar tendon bone autograft (one bone block technique). METHOD: We retrospectively evaluated a case series of patients who had received arthroscopic ACL reconstructions using patellar tendon bone autograft. Fifty-four (54) ACL reconstructions were evaluated at a mean of 38 months (range 25-62 months). Clinical assessment was made using a modified Lysholm score, documentation of International Kappanee Documentation Committee (lKappaDC), the anterior knee pain questionnaire of Shelbourne and Trumper, and by KappaTau-Rolimeter arthrometric analysis. Radiographic assessments were also performed. RESULTS: Arthrometric analysis showed that 51 knees (94%) were graded Alpha or Beta with a median laxity of 2 mm, postoperatively. The Lysholm score improved postoperatively from 70 to 89. The patellar position in terms of congruence angle did not show any significant change, and the final shortening of the patellar tendon using the Insall-Salvati ratio was 6.07%. Only three patients complained of moderate pain on kneeling, one patient was unable to participate in strenuous works and one patient complained of harvest-site tenderness. CONCLUSION: It is concluded that the use of patellar tendon autograft with a single tibial-tubercule bone block and a strip of patellar periosteum have the advantages of being available and comparable in terms of graft size and strength and shows satisfactory results with reduced anterior knee pain.

Fractures of the femoral neck treated with hemiarthroplasty. A comparative study.

INTRODUCTION: Hemiarthroplasty is the treatment of choice in the management of displaced intracapsular fractures of the proximal femur in old patients with low functional demands. AIM: To assess the effectiveness of cementless Austin-Moore and the cemented Thompson prostheses used in the treatment of displaced intracapsular fractures of the proximal femur. PATIENTS AND METHODS: We studied retrospectively 376 patients with fresh, displaced, nonpathological femur neck fractures. They were treated with either a cementless Austin-Moore prosthesis or a cemented Thompson prosthesis. Criteria for the choice of the prosthesis were the fracture site on the neck of the femur and the bone quality. The follow-up period was 3 to 8 years and the number of reviewed patients was 122. RESULTS: The Thompson prosthesis group showed slightly better results. Acetabular erosion rate was significantly lower in the uncemented group while loosening rate here was significantly higher. CONCLUSION: Advantages and disadvantages were identified in both groups although we believe that none of the approaches proved definitively superior to the other.

Mid-term results of total knee arthroplasty after high tibial osteotomy.

BACKGROUND: The outcome of total knee arthroplasty (TKA) after high tibial osteotomy (HTO) is still controversial. In order to determine if osteotomy has any effect on this outcome we performed a medium-term review of a cohort of patients with knee osteoarthritis. MATERIALS AND METHODS: Thirty-two patients (38 knees), who were treated with a HTO before the TKA during the last 8 years, were compared with a matched group who underwent primary TKA. The knees were evaluated preoperatively and postoperatively according to the scoring systems of the Knee Society and Hospital for Special Surgery (HSS). The anteroposterior tibiofemoral alignment, the Insall-Salvati patellar position ratio, range-of-motion and the location of the lateral joint line, were also recorded. The patients were reviewed with a mean follow-up of 4.5 years after TKA. RESULTS: The preoperative and postoperative knee scores had no statistically significant differences between the two groups. So was the case with the intraoperative releases, blood loss, thromboembolic or neurologic complications and infection rates in either group. Access to perform the arthroplasty was reportedly more difficult and took an average of 25 min longer. A significant difference (p < 0.05) was detected in terms of impingement of the tibial stem on the lateral tibial cortex, patellar subluxation and patella baja between the two groups but this did not have any influence on the outcome of the prosthesis. Knee alignment and stability so as range of motion (ROM) measurements were also found with no statistical significance. CONCLUSION: Although we did manage to detect statistically significant differences mainly in radiographic results between the two groups, this situation did not appear to influence the clinical outcome of the patients, however. The fact that most of the patients had good or excellent results at an average follow-up of 4.5 years suggests that HTO does not have a significant negative effect on later TKA.

External fixation of intertrochanteric fractures in elderly high-risk patients.

This study concerns 56 elderly high-risk patients with an intertrochanteric fracture of the femur, who were treated with the Citieffe/Ch-N external fixator between November 2002 and February 2004. A short intraoperative time (37 minutes), no need for peroperative blood transfusion, fast mobilisation and a short hospitalisation (average 6 days, thus reducing the total cost) were noted. Union was obtained in all patients after 6 months. There was no significant difference between the functional status before the injury and at follow-up after 12 months (p > 0.05). No deep pin track or wound infections occurred, but a superficial skin reaction was seen in 39.3%. The mortality rate was 16.1% at 6 months, and 20.4% at 12 months, which contrasts favourably with other types of treatment. External fixation with this device can be used successfully for the treatment of elderly high-risk patients with intertrochanteric fractures.
