ABSTRACT

PURPOSE: Fully conforming, mobile-bearing total knee replacement (TKR) was initially designed using a posterior cruciate-sacrificing (CS) technique. Rotating-platform TKR that could also be performed retaining the posterior cruciate developed afterwards. The purpose of this study was to compare the clinical and functional outcomes of patients who had either cruciate-retaining (CR) or cruciate-sacrificing (CS) TKR at a minimum follow-up of 2 years with the same prosthetic design. METHODS: One hundred and two consecutive TKR (88 patients) were performed at the same institution either with CS (56 TKR-49 patients) or with CR (46 TKR-39 patients) technique. Patients were followed at a minimum of 2 years. Patients were evaluated for articular range of motion, complication rate (infection, loosening) and clinical outcome measures included the pain and functional components of the Knee Society Score. RESULTS: The two groups (CS, CR) were homogeneous. At final follow-up, no significant difference was seen between the two surgical techniques in terms of ROM, pain and functional level, and revision rate. CONCLUSIONS: This study showed that for this given mobile-bearing, fully conforming prosthetic design, sacrificing or resecting the PCL does not influence the clinical and functional outcomes at a minimum of 2-year follow-up. Surgeons may indifferently choose one of the two options (CS, CR) according to their preferences. LEVEL OF EVIDENCE: Case series, level IV.

ABSTRACT

BACKGROUND: Traumatic hip dislocation with fracture of the posterior acetabular wall is associated with high rates of residual invalidity. METHODS: The records of patients who underwent surgical treatment of traumatic dislocation of the hip associated with an isolated fracture of the posterior acetabular wall from 1999 to 2009 were reviewed. There were 30 men and 12 women, who at the time of the trauma had a mean age of 42 years (range 21-65). Mean follow-up duration was 5 years (range 2-10). Pre-operative fracture evaluation was based on the classification of Judet et al. which divided this fractures into three types: type 1 is characterized by a single fracture line separating a single bone fragment from the remaining part of the posterior wall; type 2 fracture involves several fragments of the posterior wall and in type 3, a type 1 or type 2 fracture is associated with a sunk cancellous area in the acetabular wall medial to the fracture line but not affected by it, due to the shear impact of the femoral head at the time of dislocation. Clinical evaluation of the outcome was according to the criteria of Merle D'Aubigné and Postel as modified by Matta. Outcomes were divided into excellent/good and fair/poor. Since treatment was standard, data were further analyzed to assess the relative importance of age, sex, follow-up duration, sciatic nerve lesion on admission and mechanism of injury, using the Chi-square test. RESULTS: Full clinical recovery without sequelae or radiographic abnormalities was achieved by 10 patients, 8 with type 1 fracture and 2 with type 2 fracture. A good outcome was seen in 13 patients, 3 with type 1 fracture, 9 with type 2 fracture and 1 with type 3 fracture. Eight patients, 3 with type 2 fracture and 5 with type 3 fracture, had a fair outcome. Only follow-up ≥6 years influenced outcome significantly (p > 0.005). CONCLUSION: Our conclusions in light of our experience are that in type 1 lesions, anatomical reduction and stabilization achieve excellent outcomes, both clinical and radiographic; type 2 fractures pose greater prognostic problems because their outcome is determined by the success of the reduction and fixation of a multi-fragment fracture; finally, different considerations apply to type 3 fractures, which present varying degrees of comminution and an impacted acetabular surface: their outcome depends on the quality of the anatomical and morphological restoration of acetabular congruence.

ABSTRACT

There is no agreement on the ideal type of surgical management for Achilles tendon rupture. The present randomized prospective study was performed to compare outcome data of open and percutaneous repair in the treatment of Achilles tendon rupture. Forty consecutive patients with acute rupture of Achilles tendon were recruited. Patients were randomized to receive open (group A) or percutaneous repair with Tenolig (group B). All patients followed the same rehabilitation protocol except for slight differences in the duration of immobilization. Follow-up included objective evaluation (at 4 and 12 months), subjective evaluation using the SF-12 questionnaire (at 24 months), and bilateral ultrasound scanning and isokinetic testing (at 12 months). The differences in the parameters evaluated clinically were not significant except for ankle circumference, which was significantly greater in group B. There were two minor complications in the open repair group and one case of failed repair in the percutaneous group. SF-12 questionnaire, ultrasound and isokinetic test data did not show significant differences between the groups. The present study demonstrates that the open and the percutaneous technique are both safe and effective in repairing the ruptured Achilles tendon and that both afford the same degree of restoration of clinical, ultrasound and isokinetic patterns. Medium-term results were substantially comparable. Percutaneous repair is performed on a day-surgery basis, it reduces cutaneous complications and operation times, and enables faster recovery, enhancing overall patient compliance. To us, these characteristics make it preferable to open repair in managing subcutaneous ruptures of Achilles tendon in non-professional sports practicing adults.
