Acute and chronic patella dislocations. Therapeutic strategies in Danish orthopedic departments.

Johannsen HG, Gad D, Heidemann ED. Ugeskr Laeger 2000 Aug 21;162(34):4523-5.

BACKGROUND.
In review of the literature there is no standard treatment of acute- as well as recurrent dislocation of the patella. Most investigations are retrospective or not randomised. Approximately 1500 patients/year with the diagnosis luxatio patellae are seen in Danish hospitals.

METHODS.
Using a questionnaire we wished to find out how these patients were treated in Danish orthopaedic departments.

RESULTS.
We found that there was no consensus on the treatment of patellar dislocation.

CONCLUSION.
We concluded that there is a need for prospective randomised studies involving a large number of patients, with a long follow up time.

Subluxation of the patella: evaluation of patellar articular cartilage with MR imaging.

Nakanishi K, Inoue M, Harada K, Ikezoe J, Murakami T, Nakamura H, Kozuka T. Br J Radiol 1992 Aug;65(776):662-7.

In patients with subluxation of the patella, injury of the patellar articular cartilage is frequently observed, and correct evaluation of this cartilage injury is extremely important for the management of these patients. Magnetic Resonance (MR) studies were performed on 102 patellofemoral (PF) joints of 51 patients with subluxation of the patella and 20 PF joints of 10 healthy volunteers. In 77 of the 102 PF joints with subluxation, arthroscopy and/or operation were performed. MR images were obtained with spin-echo and FLASH sequences, and para-axial images were obtained. We retrospectively analysed the MR findings of the 77 joints with special attention to the surface and thickness of the cartilage, and classified them into four grades. These MR grades were compared with the grades on arthroscopy, and the following results were obtained: MR grade 0, normal cartilage (n = 27, sensitivity 90.9%, specificity 74.2%); MR grade 1, thickening of the cartilage (n = 24, sensitivity 50%, specificity 89.1%); MR grade, surface irregularity of the cartilage (n = 20, sensitivity 85%, specificity 94.7%); MR grade 3, loss of the cartilage (n = 6, sensitivity 100%, specificity 100%). Although the early changes observed by arthroscopy were underestimated from the MR images, MR imaging proved to be extremely useful for evaluating moderately or advanced patellar cartilage injury.

UDSPÆNDING
(5 min)

Lie on your back. Draw the injured leg up towards your head so that the muscles in the back of the thigh become increasingly stretched. Perform the exercise with outstretched as well as bent knee. Hold the position for 20 seconds and relax for 20 seconds before repeating. The exercise can also be performed standing with the injured leg outstretched on a chair while the upper body is bent slightly forwards.

Stand with support from the back of a chair or the wall. Using your hand, bend the knee and draw the foot up and your knee slightly backwards so that the muscles in the front of the thigh become increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating. The exercise can also be done lying down. If you lie on your stomach you can draw the foot up by using a towel.

Seesaw. Balance on two legs, possibly using a hand as support against the wall, balancing subsequently on one leg without support. Look straight ahead and keep knees bent.

Sit on a chair with elastic around the ankle, facing the elastic. Lift the leg and slowly bend and stretch the knee.

Sit on a chair with elastic attached to the ankle. Raise the leg and slowly stretch and bend the knee.

Stand on the healthy leg with the elastic around the inside of the injured leg. Move the injured leg from side to side in a slow smooth movement. Moving the position of the elastic lower down the leg can increase the load.

Stand on the healthy leg with the elastic around the outside of the injured leg. Move the injured leg from side to side in a slow smooth movement. Moving the position of the elastic lower down the leg can increase the load.

Stand with your back against a wall with a ball or firm round cushion between the wall and your back. Slowly go down to bend your knee 90 degrees before slowly rising up again.

Stretching is carried out in the following way: stretch the muscle group for 3-5 seconds. Relax for 3-5 seconds. The muscle group should subsequently be stretched for 20 seconds. The muscle is allowed to be tender, but must not hurt. Relax for 20 seconds, after which the procedure can be repeated.

The time consumed for stretching, coordination and strength training can be altered depending on the training opportunities available and individual requirements.

Meniscal injury in children: long-term results after meniscectomy.

Dai L, Zhang W, Xu Y. Knee Surg Sports Traumatol Arthrosc 1997;5(2):77-9

Twenty-four children who underwent open total meniscectomy were reviewed and followed-up for an average of 16.1 years (range 6-33 years). There were 7 boys and 17 girls aged between 7 and 16 years (average 12.5 years). Excellent and good results were noted in 62.5% of the patients. Eighty-seven of the children showed radiographic degeneration of the knee joint. This study in a Chinese population indicates that meniscectomy is not a benign procedure in children, and total meniscectomy should be avoided as far as possible.

Treatment of intrasubstance meniscal lesions: a randomized prospective study of four different methods.

Biedert RM. Knee Surg Sports Traumatol Arthrosc 2000;8(2):104-8.

This study examined the effect of four different methods for treating intrasubstance meniscal lesions. Forty patients (21 men, 19 women; age 30.4 years, range 16-50) with an isolated and symptomatic painful horizontal grade 2 meniscal lesion on the medial side (documented with MRI) were included. Patients were randomly assigned by the birth date to one of four treatment groups: group A, conservative therapy (n = 12); group B, arthroscopic suture repair with access channels (n = 10); group C, arthroscopic minimal central resection, intrameniscal fibrin clot and suture repair (n = 7); and group D, arthroscopic partial meniscectomy (n = 11). The average length of follow-up was 26.5 months (range 12-38 months). Follow-up evaluation consisted of clinical examination with the findings recorded according to the IKDC protocol, radiographs, and control MRI. Group A had 75% normal or nearly normal final evaluation at follow-up, group B 90%, group C 43%, and group D 100% normal or nearly normal at follow-up. These short-term results indicate that intrasubstance meniscal lesions can be treated best by performing partial meniscectomy. To preserve the important function of the meniscus, arthroscopic suture repair with access channels might give even better medium- to long-term results. Conservative treatment is often not satisfactory. Additionally, our findings show that MRI examinations are not superior to accurate clinical examinations.
