Knee joint proprioception in patients with posttraumatic recurrent patella dislocation.

In 30 healthy volunteers with clinically inconspicuous knee joints and nine patients with posttraumatic recurrent patella dislocation, the proprioceptive abilities of the knee joint were evaluated by an angle reproduction test. The results of the control group showed no gender- or dominant-specific difference. The patient group showed a significant deterioration of proprioceptive capability in the injured knee joint. Even in the contralateral, uninjured knee joint, the angle reproduction test result was significantly reduced compared with the control group. After applying an elastic knee bandage, the control group and the patients with patella dislocation showed a significant improvement of the proprioceptive capability.

Recurrent posterior dislocation following primary posterior-stabilized total knee arthroplasty.

In our series of 136 patients with primary total knee arthroplasty using posterior-stabilized prosthesis, a female patient with Parkinson disease developed posterior dislocation of the knee 9 months after surgery. Eventually, the dislocation became recurrent, occurring several times a day. The patient made the reposition always by herself. Two months after the first dislocation, we performed the revision of the polyethylene tibial insert and found wearing of the tibial insert's cam as an hitherto unreported cause of the mechanical instability of the total knee prosthesis.

Congenital hyperextension of the knees in twins.

Bilateral congenital hyperextension of the knees occurring in dizygotic twins is reported. Twin A had the mild form of the disease, genu recurvatum, while twin B had a more severe form of the disease, congenital subluxation. Hyperextension of the knee may occur as a sporadic abnormality, in conjunction with multiple dislocations or as a feature of a syndrome. Early detection and diagnosis are important, especially in the more severe forms of the condition, subluxation and dislocation, which require aggressive immediate intervention to prevent long-term sequelae. Conservative treatment consisting of manipulations and immobilization usually will correct the mild forms of the condition if instituted soon after birth. Prognosis is less favorable with delayed treatment, in the presence of other congenital anomalies, and with genetic syndromes.

10- to 20-year followup of total knee arthroplasty for valgus deformities.

One hundred eight knees in 83 patients with a valgus alignment of greater than 10 degrees underwent total joint replacement performed by a single surgeon using the same technique for ligament balancing, which involved releasing the lateral retinaculum and iliotibial band, followed when necessary by detaching the lateral collateral ligament and popliteus tendon from the femur. Sixty knees in 46 patients had followup of at least 10 years and were the focus of study. At an average followup of 14.1 years, the mean Knee Society knee score was 88.7 and the mean functional score was 69.2. Postoperative knee alignment averaged 4.5 degrees with 75% of the knees corrected to between 2 degrees and 7 degrees valgus. Postoperative flexion averaged 101 degrees. There were no cases of peroneal nerve palsy or patellar dislocation. Six knees underwent revision surgery with two for sepsis, three for aseptic loosening, and one for a traumatic patella fracture. Radiographic component loosening also was seen in one knee. The probability of retention of the prosthesis was 91% (+/- 11.7%) at 13.2 years. Although the results in this group of patients seem acceptable, the rate of postoperative instability for all patients treated using this ligament balancing technique was 24%. Because of the high rate of instability, a new soft tissue release technique has been developed and is the preferred method for ligament balancing of the valgus knee during total knee arthroplasty.

[Thermography in sport injuries and lesions of the locomotor system due to sport].

Using the infrared-thermography a exact picture of the body surface can be obtained. Injuries are recognized by a local hyperthermy, if the impaired structures do not lie too deep under the body surface. In combination with anamnesis and clinical and radiological examination the infrared-thermography plays an important role in the diagnosis, management and control of therapy. The results of examinations of 82 patients with distorsions, ruptures of tendons or ligaments, injuries of the meniscus and tendo- and chondropathias as well as of 50 athletes are described. In all cases a hyperthermy was found in the area of injury. In those cases, in which an injury was not the cause of the hyperthermy, other processes could be found (furunculosis, phlebitis, tumor).
