Hip Arthroscopy

Hip arthroscopy is a minimally invasive surgical procedure that allows orthopaedic surgeons to diagnose and treat hip joint conditions. This procedure is safe and effective in addressing a variety of hip-related issues, particularly labral tears and femoroacetabular impingement (FAI).

FAI is a well-recognized cause of hip pain in young adults. Patients with FAI have an aspherical femoral head and/or prominent socket that results in premature contact between the two during hip range of motion, leading to cartilage and labral damage, pain and early osteoarthritis. Minimally invasive surgical treatment of FAI is effective to improve hip function and reduce or eliminate symptoms.

The labrum is a ring of cartilaginous tissue that encircles the hip socket (acetabulum). It plays a crucial role in maintaining hip joint stability, distributing joint forces, and ensuring optimal joint lubrication.

Tears or damage to the labrum can result from trauma, repetitive motion, or degenerative conditions including femoroacetabular impingement or FAI. Individuals with labral tears may experience pain, catching sensations, and limited range of motion in the hip.

During hip arthroscopy, small incisions are made around the hip joint, through which a camera and surgical instruments are introduced. The damaged or torn labrum is identified, and the surgeon repairs it using sutures and anchors. This restores the labrum to its anatomical position, facilitating its normal function.

Osteoplasty, the reshaping of the femoral head and/or neck and acetabulum, is important to eliminate impinging bone. It provides excellent outcomes for most FAI patients.

  • Cam-type FAI is caused by anatomic abnormalities of the head of the femur. Osteoplasty reshapes the femoral head-neck junction to restore normal contours.
  • Pincer-type FAI is caused by an overhanging acetabular rim. Osteoplasty is performed to remove excess bone at the rim of the acetabulum in order to recreate more normal contours.

The removal of these bony prominences reduces the impinging forces on the hip joint, alleviating pain and mitigating the risk of further labral and cartilage damage.

Physiotherapy after hip arthroscopy for femoroacetabular impingement is something that many patients and physiotherapists do not have familiarity with. If you are undergoing this procedure, here are several pearls that will help you progress smoothly and achieve your rehab milestones while also minimizing the risks of any flare-ups or complications.

1. In the first 2 weeks, the main goal is to protect the hip joint and avoid irritation. In particular it’s important to avoid hip flexor tendonitis, muscular irritation and anterior capsular pain/pinching. A few tactics to do so include:

  • Assisting the operative leg by a family member or using the nonoperative limb, avoiding sitting for more than 30 minutes and lying prone for 2-3 hours a day.
  • Avoiding hip flexion more than 90 degrees, internal/external rotation more than 20 degrees, and preventing more than zero degrees prone hip extension for the first 3 weeks.
  • Riding a stationary bike with a high seat and low resistance can be started in the first week for 20 min/day.
  • Performing Isometric exercises involving quad sets, gluteal sets, and supine transverse abdominis activation on the first postoperative day e. Avoid pushing through pain.

2. Crutches should be used for protected weightbearing for 4-6 weeks

3. From weeks 2-9, the main goal is to develop a normal gait pattern (i.e. non-compensatory gait and progression)

  • In order to do this it is important to get normal hip motion, particularly in hip extension.
  • Without normal hip extension it will be difficult to get a normal gait.
  • In this phase, working on proximal/core (trunk, lumber, pelvic) motor control and stability are also very important to help develop a normal gait.
  • The most challenging part during this timeline is getting off crutches. It is important not to force the timeline. Patients should wean off crutches until they can ambulate without pain using a normal gait pattern.

4. After week 9, assuming the goals of the prior timelines have been met, the aim is to return patients to the pre-injury level

  • This part of the rehab is more individualized. If patient demands are higher, rehab will take longer.
  • Closed chain exercise progression in the form of squats, lunges and rotational movements can be initiated.
  • Treadmill walking typically beings around 3 months after surgery and sports specific/ functional training can begin.

5. After week 14, the main goal is to return to sports. Introducing exercise for power, skill endurance and agility occurs in this phase. Running is permitted around five months.

6. After six months, patients are usually cleared to go back to full activity The above phases and timelines are general guidelines.

There may be various modifications to the rehab protocol which in turn is determined by the exact operative procedure. For example, if a microfracture of the hip is also performed, than protected weightbearing with crutches is often extended to 6 week.

Furthermore, it is important to look for any flare-ups during the rehab process. If this happens, the key is to shut down activity and rest for at least 24 hours. Another red flag is to progress too quickly in the rehab timelines without achieving a normal gait pattern. This can cause muscular overactivity and subsequent pain and/or inflammation.

Pro-actively discussing triggers and aggravating factors with your physiotherapist (e.g. sitting too long, actively lifting the surgical leg too early in the postoperative period, early weight-bearing, sleeping position, etc.) will help you stay out of trouble and navigate a smooth recovery process.

Hip arthroscopy for labral repair and osteoplasty offer a minimally invasive solution to address specific hip joint pathologies. With advancements in surgical techniques, equipment, and postoperative care, this procedure has become a mainstay in orthopaedic surgery, promising favorable outcomes for patients suffering from labral tears and FAI.

Hip arthroscopic provides good outcomes and high rates of return to play. However, it is not without risk. The procedure has a steep learning curve.
