2 ABSTRACT The knee complex is one of the most often injured joints in the human body. The myriad of ligamentous attachments, along with numerous muscles crossing the joint, provide insight into the joint s complexity. This anatomic complexity is necessary to allow for the elaborate interplay between the joint s mobility and stability roles. The knee joint works in conjunction with the hip joint and ankle to support the body s weight during static erect posture. Knee traumas are frequent in adult active population specially those involved in high risk sports like ski, martial arts, soccer and others. This kind of traumatic injury hugely impedes the daily living activities. Meniscus injury is very common in knee traumatology. The meniscus can be injured in many ways and on different locations (flap tear, bucket handle tear, vertical tear, horizontal tear, complex tear), thus causing a variety of histories and different clinical findings. 1

4 ANATOMICAL DESCRIPTION The fact that the knee must fulfill major stability as well as major mobility roles is reflected in its structure and function. The knee complex is composed of two distinct articulations located within a single joint capsule: the tibiofemoral joint and the patellofemoral joint. Tibiofemoral congruence is improved by the medial and lateral menisci, forming concavities into which the femoral condyles sit. Figure 1: knee joint anatomy In addition to enhancing joint congruence, these accessory joint structures play an important role in distributing weight-bearing forces, in reducing friction between the tibia and the femur, and in serving as shock absorbers. Although compressive forces in the knee may reach one to two times body weight during gait and stair climbing and three to four times body weight during running, the menisci assume 50% to 70% of this imposed load (pg Joint Structure and Function ). The meniscus consists of semilunar shaped fibrocartilage tissue. There are two menisci, a lateral one which is somewhat more circular than the C-shaped medial meniscus. A normal lateral meniscus forms five-sixths of a circle. It has an average width of about 12 mm and a height of 4 5 mm, although the normal anatomy varies considerably with regard to dimension and shape. In adults, the C-shaped medial meniscus covers 50% of the medial tibial plateau and is connected firmly to the joint capsule by coronary, meniscotibial, and deep medial 3

5 collateral ligaments; whereas the lateral meniscus covers 70% of the lateral tibial plateau and has firm anterior and posterior attachments, while its lateral joint capsule attachment is loose because there is no attachment at the popliteal hiatus and lateral collateral ligament. Therefore, the normal lateral meniscus has more mobility than the medial meniscus, allowing an increased excursion of the lateral femoral condyle (pg Sports Injuries Prevention, Diagnosis, Treatment, and Rehabilitation ). The meniscus also serves to help distribute the forces between the two bones over a greater area (rather than point to point), helps supply nutrition to the cartilage that lines the bones (articular cartilage), and helps stabilize the knee. Figure 2: meniscus tear The meniscus is a rubbery tissue that loses its elasticity with age. Nonetheless, each individual meniscus can be torn. Meniscus tears are very common, occurring in up to one third of all sports injuries. The inner or medial meniscus is injured most often. 4

6 CASE STUDY Using my expertise as a certified physical therapist, with a bachelors and master s degree in this field and combining it with the knowledge and expertise in the pilates method I am able to work frequently with clients with musculoskeletal pathologies or injuries that are suitable to be treated in a pilates studio environment, especially after surgery and/or in the later stages of their rehabilitation program. The perfect example is Mihaela S, a client of the gym facility where I regularly teach private sessions and group classes. She used to come for pilates and yoga group sessions frequently for few years. In the winter of 2016 a ski injury to her left knee is what brought a lot of pain and discomfort to her and after investigations she was recommended for surgery. Figure 3: ligaments of the knee Her diagnosis was posterior meniscal longitudinal tear of the lateral meniscus, incomplete tear of the lateral patelofemural ligament (lateral retinacul) and lesion of the posterior-medial face of the patella due to abnormal taking. For the surgery, the doctors used laparoscopic technology for minimum damage to the surrounding tissues and a faster recovery time. After surgery Mihaela S. had no immobilization devices and she did 20 sessions of physical therapy at the hospital. 5

7 After her physical therapy sessions she contacted me for some pilates private lessons in which she wanted to continue her knee rehabilitation program but also to get the rest of her body back in shape. In our first session I did an evaluation of her knee and noted that she had pain and swelling, muscle atrophy on her left thigh especially on her VMO (vastus medialis oblique), the knee joint could not move past 120 degrees of flexion and she had restriction for movements like squats, lunges and quatrupedia position. My approach for Mihaela`s rehabilitation plan was according to the following stages: 1. Decrease pain and swelling 2. Improve knee range of motion and flexibility 3. Increase strength and recruitment of quadriceps and other lower extremity muscles 4. Correct movement patterns CONDITIONING PROGRAM USING BASI BLOCK SYSTEM Warm up: In this category my goal was to get my client ready for the session both physically but also mentally, so while getting her muscles and joints ready I also tried to get her attention to what we were going to do and away from her usual thoughts. I used 6-8 repetitions for each exercise. Chest lift on the mat Chest lift with rotation on the mat Supine spine twist Roll Up on the mat Roll Up with Roll Up Bar on the Cadillac Pelvic curl (mat) 6

8 Rolling (Roll-Like-A-Ball) Foot work: This category was very important in the overall rehabilitation program as it builds the much needed tonus in the muscles around the knee joint. Below, you have an example of the reformer foot work series however the Cadillac was also used very often for this category. I used 10 repetitions for each exercise. Parallel toes foot work series Parallel hells foot work series V position toes foot work series Open V toes foot work series Open V hells foot work series Prehensile foot work Series Calf Raise foot work Series Prances foot work Series Hip work: I put this category right after the hip work as I wanted to benefit from the lower body focus that Mihaela had gotten with the previous exercises, also from a physiological point of view I considered to be beneficial to build the stimulus to the lower limbs muscles by having these two categories one after the other. Also, trying to build tonus and volume to the lower limbs muscles, for this category I used 10 repetitions for each exercise. Frog (basic leg springs) Circles (down, up) (basic leg springs) Walking (basic leg springs) Bicycle (basic leg springs) Bicycle (single leg supine) Frog (single leg supine) Circles (down, up) (single leg supine) Hip extension (single leg supine) 7

9 Changes (single leg side series) Scissors (single leg side series) Abdominal work: Mini roll-ups Mini roll up oblique Double legs (abdominal legs in straps) Spinal articulation: Roll up bottom loaded Teaser 1 (Cadillac) Bottom lift with extensions Jack Knife (Wunda Chair) Stretches: Standing lunge hamstring stretch Bottom lift with extensions group Full body integration 1: Scooter Arm work: Circles (up, down) (arms standing series) Chest expansion (arms standing series) Butterfly arms (standing series) Full body integration 2: Up stretch 1 (up stretch series) Long stretch (up stretch series) Up stretch 2 (up stretch series) Up stretch 3 (up stretch series 8

10 Leg work: Leg press standing Terminal knee extension Fig 4 (a) and (b) Sitting knee flexion Fig 6 (a) and (b) Figure 4 (a) Figure 4 (b) Figure 6 (a) Figure 6 (b) Sitting knee flexion, single leg Fig 7 These last three exercises were presented in the Injuries and Pathologies workshop and were very beneficial for my client s needs. I used ten repetitions for each of the leg work exercises. Figure 7: sitting knee flexion, single leg 9

11 Lateral flexion/rotation: Side reach (push through series) Saw (push through series) Back extension: Prone 1 (push through series) Prone 2 (push through series) Hanging back (hanging series) CONCLUSION Pilates was a perfect match for Mihaela S. as she needed method of training that would bring quality and control into every movement. She needed a system of training that would provide balance between rehabilitating her knee including the quadriceps, hamstrings, glutes and all the other important muscles along the lower limb but in the same time build up the rest of the body and state of the mind. Going through the process of rehabilitation, pilates is a method able to provide exercises and techniques for stability, improve muscle recruitment and activation, improve the power exerted by each muscle, and also improve muscle mass to counter the atrophy noticed after surgery. In the approach to rehabilitation the injured knee the pilates method in general and the BASI way in particular was a valuable help. Using all the knowledge from the comprehensive course and also from the Injuries and pathologies workshop, I was able to bring captivating, safe and very efficient exercises and principles that made each session a definite step forward on Mihaela`s way to rehabilitation and general wellbeing. 10
