Shoulder
Whats next if conservative tx doesn’t work? 3
- Shoulder arthroscopy

- Repair torn tendons
Recovery Worst case scenario is cuff repair 1. Healing phase is how long? 2. When does it start? 3. Time in full time sling and part time sling? 4. Rehab? 5. Strengthening? 6. Typically takes how long?
- 6 weeks: Healing phase
- Typically start therapy at 3 weeks
- Full time sling 3 weeks/part time 3 weeks
- 6 weeks: Rehab
- 6 weeks: Strengthening
- Typically 3-4 months…start resuming previous activities…SLOWLY
- What kind of joint is the knee?
2. There are 3 seperate compartments: What are they?
- A diarthroidal joint: a hinge joint
- 3 separate comparments
- Patellofemoral
- Medial
- Lateral
Two main types of cartilage in the knee? Describe them?
- Articular cartilage: a thin lining of resilient connective tissue that serves as padding and an ultra low friction surface
- Meniscal cartilage: serve to deepen the contact of the femur on the tibia, provide stability, distribute force
- Joint reaction force in the knee is about __ times body weight when walking
- This is absorbed by the what? 2
- 3
- menisci
- articular cartilage
4 main ligaments in the knee?
- Anterior Cruciate Ligament (ACL)
- Posterior Cruciate Ligament (PCL)

The Knee
Problems of the knee?
5

Meniscal Tear Symptoms? 5
- Focal pain, typically intermittent
- Swelling
- Nightime pain
- Pain with activity
- Catching/locking
Meniscal Tears
Tx options?
3
- Physical Therapy
- Injections
- Arthroscopic surgery
Arthroscopic surgery
- What is it?
- Better by when?
- remove/fix the tear
2. 80-90% better by 6-8 weeks
Ligament injuries ACL 1. Fix in who? 2. Age restriction? 3. CI in who?
PCL
- Fix when?
- CI?
MCL
- Tx?
- Weight bearing?
LCL
- Tx?
- Fix if what?
ACL
- Fix in active, physical individual
- NO real age restriction
- Contraindicated if significant arthritis
PCL
- Fix when symptomatic
- Contraindicated if significant arthritis
MCL
- Brace for six weeks
- Weight bearing as tolerated
LCL
- Brace
- Fix if part of a complex of lateral injuries
Cartilage injury
- When do we generally find out the level of severity?
- Variety of treatments dependent on the severity? 2
- Typically unclear of severity until the time of arthroscopy
- Variety of treatments dependent on the severity
- “smooth down”
- Microfracture
- When would we do a cartilage transplant?
- An attempt to prevent what?
- Not useful in who?
- Treatment for smaller, focal cartilage defects
- An attempt to prevent the progression to osteoarthritis
- Not useful in degenerative arthritis
Knee injuries
Meniscus tear with mild/mod arthritis
1. How common?
- Meniscus tear is the __________ problem
- Treatment based on what?
- If symptoms are improving?
- If not or worsening, then consider?

Treatment consists of ?
5

Lateral and Medial Epicondylitis
For recalcitrant cases? 2
- Consider corticosteroid injection
- Platelet rich plasma injection
Most of the time these go away. Some require surgery

- Extracted from?
- Delivered and works how?
- High concentration of functionally viable platelets and their associated growth factors
- Extracted from a small amount of patients blood: 9-18cc
