Abstract

To see the clinical result of Modified Judet’s Quadricepsplasty (MJQP) with patella traction at BARI-ILIZAROV ORTHOPAEDIC CENTRE for the treatment of knee extension contracture.

Materials and methods: We received 16 patients with knee extension contracture treated by MJQP with patella traction from January 2015 to January 2021, at our BARI-ILIZAROV ORTHOPAEDIC CENTRE. The age at revision surgery was 25-58 years. The time between fracture treatment to MJQP was 4 to 20 months and our follow up was 10-30 months. We assessed pre-operative and post-operative range of motion (ROM).

Results: Knee range of motion pre-operatively was 5-50 (35± 10)° and 35-85 (55±10)° after MJQP and in average of 0-35(18+10) °. We applied patella traction for 12-14 (10±3)° When we removed the patella traction the knee range of motion at that time was 95-110 (93±4)° and increase of 10-70 compared with the range of motion after release of all arthrofibrosis in the joint. Our follow up time was 12-35 (19±5) months. Knee range of motion at first follow up was 85-135 (105±13)°, an increase of 45-105 (70±15) ° compared with pre-operatively and of 10-45 (12±12)° compared with the range of motion after patella traction removed. Knee function was excellent in 12 cases (70%), good in 3 (27%) and fair in one (3%).

Conclusion: MJQP with patella traction lengthens the contracted Quadriceps femoris gives excellent result with proper post-operative care and CPM therapy.

Introduction

Extension contracture or stiff knee is a complication of femur fracture, particularly in the supracondylar region. After a fracture in the supracondylar region, we face difficulties in gaining full range of motion in the knee. Stiffness of the knee occurs due to periarticular and intramuscular adhesions. Severe stiffness can’t be treated by conservative treatment followed by exercises.8

The pathological conditions that limit knee flexion include:

  1. Arthrofibrosis
  2. Contracture of the joint capsule.
  3. Quadriceps muscle contracture.
  4. Fascial contractures.

The knee extension contracture or knee sti ness requires surgical interventions in 15.5% of patients. The definition of knee extension is controversial, the criteria are

  1. Decreased knee flexion (<85°)
  2. Limited knee range of motion (<70°)
  3. Increased knee flexion (>15°) and
  4. Decreased knee flexion (<75°).1,2

Maintenance of adequate knee range of motion is essential for normal knee function. It has been proved by gait analysis that 65° knee flexion is required for daily activities and for level walking, 83° for stair ascent, 90° for stair descent, 115° for squatting or kneeling, and 94-105° for rising from sitting to standing.3 A knee flexion angle of 110° is required for daily life. The Bangladeshi people have a relatively greater necessity for knee flexion and squatting and sitting cross-legged are more common due to religion. That is why surgical intervention is necessary to increase the knee range of motion for Bangladeshi people.

Recent management for post-traumatic knee extension contracture include

  1. Rehabilitation and physiotherapy,
  2. Closed arthrolysis under anesthesia.8
  3. Arthroscopic release.4
  4. Quadricepsplasty.5

Quadricepsplasty includes:

  1. Conventional quadricepsplasty,
  2. Thompson and Judet techniques
  3. Modified Judet's quadricepsplasty (MJQP) combined with Ilizarov frame6 needs high expertise. That is why till today no consensus on the best treatment for post-traumatic, post-operative knee extension contracture. The” Ilizarov law of tension-stress” is slow and steady traction on a living tissue creates a stress which is metabolically activated and which can stimulate histo-neogenesis.7 On the basis of that we tried to release the contracture of quadriceps femoris by patella traction. For the last 7 years at our BARI-ILIZAROV ORTHOPAEDIC CENTRE we treated post-operative knee extension contracture using the combination of MJQP with patellar traction to lengthen the contracted quadriceps femoris which improves knee function within a short period of time.

Materials and methods

Inclusion criteria:

  1. age>20 years, ≤ 62 years,
  2. Anamnesis of femur fracture,
  3. pre-operative knee ROM was ≤ 50°,
  4. MJQP with patellar traction.

Complications

During our treatment, in one case cutting of patella by Kirschner’s wire and necrosis was observed of the skin around the knee, and pin tract infection were also recorded. We measured the ROM by our orthopaedic team. By using goniometer, we measured the range of movement. The stationary arm was placed from the greater trochanter to the lateral condyle, and the movable arm was placed from the head of the fibula and the lateral malleolus.

Surgical techniques
Position of the patient in supine; we prefer spinal anesthesia. We recorded range of motion; flexion and extension after anesthesia. Our MJOP was performed in 2 steps surgery.

First, a lateral incision is made from the tibial tubercle which is extended through the lateral patella, up to distal 1/3 of the femur. The fibrosis and adhesion were released in between the lateral patellar retinaculum and lateral femoral condyle. Through extended lateral incision medial retinaculum was released from the medial femoral condyle. If we see the medial lysis is incomplete and then a short incision was made in the medial patellar region.

Secondly, the extra-articular adhesions were released in between the quadriceps femoris and femur. By doing these two steps surgery we can get knee flexion in most of the patients. If we see by doing this two steps surgery knee flexion is not markedly increased, then we can go for third step of Judet's quadricepsplasty. If knee flexion is less than 90° after two steps surgery it indicates that contracture of the quadriceps affecting the knee flexion. Then we apply patellar traction to lengthen the quadriceps femoris. 1.8 mm Kirschner wire was applied and direction of traction was vertically upward, and the heel of the affected limb was lifted above the bed. We applied traction on the operation table after operation and maintained until the knee range of motion exceeded 90° and took 10 to 14 days; and at the same time 1.5kg weight was applied on the dorsum of the affected ankle. The weight was adjusted in according to patient's need.

Post-operative treatment

According to the needs of the patient's we prescribed injection Voltalin -75 mgml, 1 ampule (intra-muscular)1/M 12 hours for 2 days and after that we prescribed oral as needed. The traction height was always adjusted in accordance with knee flexion gain each day. We routinely check the status of Kirschner's wire through the patella and clean with rectified spirit. During our follow up period we check the knee flexion and if it is >90°, we maintained the traction for another 5 to 6 days and then we asked the physiotherapist to stop that moment. We use CPM for 2 times a day, each time for 10 minutes. Our physiotherapist doing physical exercise for 30 minutes each day. Before discharging the patient, we instruct them to follow our suggestions so that they can continue the exercises at home.

Results

From January 2015 to January 2020, 16 patients with knee extension contracture were treated by MJQP (Modified Judet's Quadricepsplasty). We applied patellar traction in all the patients. After doing 2 step surgery the khee Rom could not reach 90°. We followed up the patients and before doing surgery, we counselled the patients properly. In Table 1 you can see the outcome of the patients. The time between fracture fixation and MJQP was 5 to 25 (20 ± 5) months, and follow-up period was 12-15 (15 ± 5) months. The duration of patellar traction was 10 to 16 days. After removal of patellar traction, the knee ROM was 95-105 (93 ± 4)°. The knee ROM at final follow-up was 90-135 (105 ± 14) °. No wire tract infection were seen during the follow-up.

Table 1  Clinical data of the Patients who developed knee stiffness after surgery for distal femoral fracture

Discussion

Patients with a high-energy trauma with massive soft tissue injuries may experience post-operative knee extension contracture.1,2 Why this knee contracture happens? Because of (1) adhesions of rectus femoris muscle to the femur; (2) adhesion between the patella and femoral condyles, and between tibial and femoral joints; (3) fibrosis and contraction of rectus femoris. Knee extension contracture usually treated by Thompson and traditional Judet's Quadricepsplasty. In Thompson procedure extension lag is obvious. In traditional Judet's Quadricepsplasty, 5 steps surgery is need with big incisions.3 and lots of blood is needed. But in MJQP, surgery is not big. We shall have to release intra-articular adhesions in between quadriceps femoris and lower 1/3 of the femur. We do not need to go for proximal release. After that patellar traction is applied with 1.8 mm kirschner’s wire through to patella lengthen the contracture and adhesions of the quad-riceps femoris. After 10-14 days of traction the average knee ROM was 93°, with a mean flexion gain of 40° which suggests patellar traction lengthened the contracted quadriceps femoris.
