Permanent patellar dislocation and osteoarthritis of the knee after femoral fracture in childhood. A case report.

A 52 year-old woman suffered bilateral femoral shaft fractures when she was 5 years old and they were treated surgically. She had been able to walk without pain and giving way throughout her young and adult life, however, when she came to us with a 1-year history of the right knee pain, she could walk only 10 m continuously. The right knee revealed valgus deformity with complete lateral patellar dislocation. The femoro-tibial angle was 154 degrees and arthritic change was seen in the femorotibial joint. Surfaces of both the patella and the femur were degraded. Twenty-two degrees of rotational deformity was also found internally in the involved side. Varus osteotomy with external rotation of the distal fragment and lateral retinacular release combined with reefing of vastus medialis muscle were performed. Twenty-four months after surgery, knee score and functional score were, respectively, 85/100 and 71/100, using knee society clinical rating system and there was no pain associating patella incongruity.

Patellar complications following total knee arthroplasty.

We studied the complications involving the patella following total knee arthroplasty in eighty-six knees in which thirty-four unconstrained and fifty-two offset hinge prostheses had been implanted. The abnormalities that we studied included: patellar dislocation, five knees; subluxation, eighteen knees; localized wear, three knees; and generalized wear, four knees. In twenty-three patients these complications were associated with patellar malalignment, and occurred predominantly when the offset hinge model of prosthesis was used. The complications were attributed partly to mechanical factors inherent in the prosthetic design and partly to anatomical abnormalities. Failure of the surgeon to compensate adequately for both of those factors at the time of operation was a factor in most of the complications.

[Sprains and dislocations of large joints--the knee joint].

Recent "distorsion" injuries of the knee joint should be diagnosed with great precision. While injuries that do not produce instability should be treated conservatively, early surgical repair is the treatment of choice for the unstable knee. If a reliable evaluation is not possible, a general anesthetic is required; arthroscopy is reserved for special questions. Dislocation of the knee is a true surgical emergency. The vascular insult caused by the severe injury requires immediate attention.

Acute patellar dislocation: results of immediate surgical repair.

Seventeen cases of acute, first time, lateral patellar dislocations without fracture treated by immediate surgical repair were reviewed and evaluated. Nine patellar tendon realignments and 8 medial side reefing procedures were performed. There were no recurrences of patellar dislocation. Twelve knees were painful, of which 8 were rarely painful. All but one patient were satisfied with their results and participated in any desired sport. Surgical repair of acute patellar dislocation is advocated in the young patient who anticipates future participation in athletics.

[Application of the "Taylor Spatial Frame" with unilateral implantation of a medial sledge prosthesis after posttraumatic dislocation of the femur. A complicated progression].

For years the Ilizarov fixator has been an established method for the treatment of orthopedic and trauma patients. The Taylor Spatial Frame is a software-navigated hexapod construction on the basis of the Ilizarov fixator. Unicompartmental arthroplasty of the knee is an option especially in medial osteoarthritis. The therapeutic procedure with a complicated development is illustrated by a case report on a patient with post-traumatic deformity of the femur and medial osteoarthritis of the knee.

Evaluation of patello-femoral alignment using MRI.

In evaluating patello-femoral alignment, it is not enough to assess the conformity of the joint two-dimensionally, the direction of the extensor mechanism must be examined three-dimensionally. Using magnetic resonance imaging (MRI), we adopted an ideal extensor mechanism plane intersecting the patellar facet of the femur centrally and perpendicularly. We evaluated the alignment according to the extent to which the patella and/or the tibial tuberosity deviated from the plane. The results suggested that our method is useful for indicating proximal and distal realignment. Furthermore, two-dimensional finite element analysis in the patello-femoral joint showed that peak stress was significantly higher in the dislocation group than in the no-dislocation group. This indicates that osteoarthritic change in the future is a risk in the dislocation group.

Arterial injury complicating knee disruption. Third place winner: Conrad Jobst award.

Because dislocation of the knee (DK) is accompanied by a substantial risk of popliteal artery injury, the importance of arteriography in ruling out occult arterial damage in such patients is well accepted. However, because antecedent DK cannot be ruled out in a trauma victim presenting only with severe knee ligamentous disruption (LD), we have routinely performed arteriography in all patients presenting with grossly unstable knees, whether or not DK is present. To evaluate this policy we reviewed the records of 30 patients with either DK (n = 19) or severe LD (n = 11). There was no significant difference between DK and LD in the frequency of major (22% vs 18%) or minor (38% vs 36%) vascular abnormalities. We also found that Doppler pressure measurements were highly predictive of major arterial trauma in patients in whom it was used. We conclude that arterial injury should be ruled out in all trauma victims with severe knee ligament disruption, whether or not actual joint dislocation is present.

Knee injuries in traumatic hip dislocation.

Of 187 patients treated at the author's institutions for fracture and/or dislocation of the hip during a 10-year period (1985-1994), 46 patients (25%) with a knee injury on the same side as the hip injury were evaluated 6 months to 11 years after the initial accident (mean, 3.65 years). Thirty-nine patients (85%) had symptoms or clinical signs in the knee. Ligamentous injuries overlooked in the initial examination were found in seven patients. Knee injuries often accompany hip fracture and/or dislocation, and can be produced by direct or indirect trauma. A delayed diagnosis of such injuries may lead to their treatment in the sequela phase, which complicates the final outcome. Therefore, an exhaustive physical examination is recommended for patients with traumatic hip dislocation to detect potential injuries to the ipsilateral knee. Early diagnosis and treatment of such injuries greatly improve final outcome.
