A closer look at the Robert Williams diagnosis-Dr. Morse

Recently the Boston Celtics drafted Robert Williams with the 27th pick of the 2018 NBA Draft out of Texas A&M. A 6’9” center, Williams has not had the best introduction as part of the Celtics organization. Initially he overslept causing him to miss an introductory conference call. Then he missed his flight, and had to skip his first Summer League practice with the Celtics. Unfortunately, things have not gotten much better for Williams once he started playing in the NBA summer league games. 

Williams sustained a left knee injury in the first half of the Celtics win over the 76ers, where he scored four points and grabbed a pair of rebounds before banging knees with a 76ers player. The initial diagnosis was a left knee bruise/contusion, which could’ve definitely explained his discomfort and continued time off the court. Sometimes bone bruises can be very painful, especially in the knee area, just ask NFL quarterback Sam Bradford.

Then last night, MassLive broke a story stating that Williams reportedly has an artery condition in both of his legs, a condition known as Popliteal Artery Entrapment Syndrome (PAES). Apparently NBA teams interested in Williams were aware of this condition at the time of the draft, including the Celtics, as was Texas A&M, where Williams played his college ball. The L.A. Clippers’ doctors, who performed Williams’ pre-draft physical, reportedly disseminated the results to the other organizations (a common practice) after discovering this condition. Obviously this did not deter the Celtics from drafting Williams, which should give you an idea of how significant of a concern of this condition presents.

So what is Popliteal Artery Entrapment Syndrome? As a sports medicine doctor I see all types of unique variants of the normal human anatomy, and PAES is one that I have read about but not personally seen in my practice – yet. This condition is probably misdiagnosed, as the complaints are often very vague, sometimes described as cramping, numbness, tiredness, and calf pain during exercise (this is called intermittent claudication)

In PAES, symptoms typically go away after about 3 to 5 minutes of rest, and if they do not then there are other conditions that need to be taken into consideration. PAES occurs because of an abnormal configuration of the muscles and tendons behind the knee, which when engorged with blood compress a vital blood vessel that delivers blood to the lower legs the popliteal artery. This is basically the main artery that runs through and behind the back of the knee. Compression of this artery restricts blood flow to the lower leg, resulting in poor cell nutrition and slow development of symptoms. 

So how do you get PAES? There are basically two options; either you’re born with it or you develop it. If you were born with it, this is secondary to large calf muscles (gastrocnemius or popliteus muscle). The condition can also develop over time, secondary to exercise and training, which in turn causes hypertrophy of the calf muscles, thereby compressing the popliteal artery.

 Who is at risk for PAES? This condition most commonly occurs in male athletes under the age of 30 – Williams is 20. Certain sports increase the likelihood of developing the condition, including soccer, football, rugby, and runners. Reportedly less than 3% of people who are born with the muscle variant/defect that can lead to PAES develop the symptoms, consider it a case of bad luck for Williams.

How is this condition diagnosed? This is not something your typical family medicine doctor or orthopedic surgeon will usually diagnose. While many of them will be aware of the condition, typically the patient is referred to a sports medicine specialist or vascular surgeon for a complete work-up. Evaluation begins with checking the pulses of the foot and popliteal artery, first at rest. Certain diagnostic tests can be used to diagnose the condition including an ankle brachial index (ABI) with and without exercise – this test basically measures the blood pressure in the arms and legs before and after exercise. Another options include Duplex Ultrasound, Computed Tomographic Angiography (CTA), or Magnetic Resonance Angiography (MRA). Each of these options uses a form of imaging to evaluate the arteries and sometimes even the muscle and tendons as well. 

Once diagnosed, what are the treatment options? The most common treatment is careful observation, along with modifications to lifestyle and exercise. Surgery can also be done to correct the problem, where the muscles and tendons are surgically released to alleviate the compression of the popliteal artery.

In Williams’ case, I completely expect the Boston Celtics medical staff to carefully observe him with serially monitored ABI’s of his lower extremities. If this issue continues to bother Williams, especially in the event of a situation where he has to play on back-to-back nights, surgery may be the best option. Surgery for this is typically pretty straightforward and often involves a quick hospital stay. A normal follow-up protocol includes serial ultrasounds of the repaired artery as well as lower extremity blood pressure checks at 4 weeks, 8 weeks and 1 year.

In review, new Boston Celtics draft pick Robert Williams was diagnosed with a condition called popliteal artery entrapment syndrome, which causes an aching, numb and tired pain in the calves after exercise and resolves with rest. The expectation is that Williams will be monitored closely, and his exercise schedule will be adjusted accordingly.

What to expect from the Clint Capela thumb injury-Dr. Patel

Published

on

The Houston Rocket’s center Clint Capela is expected to miss 4- 6 weeks with a reported thumb ligament injury. He is not expected to need surgery but may seek a second opinion.

Capela likely injured one of the collateral ligaments at the thumb. There is one on the inside of the thumb and one on the outside. Both of these are important for gripping activities and are commonly injured in basketball players. The MRI most likely revealed a partial ligament injury if he is not undergoing immediate surgery. These are usually protected with a cast or splint for about 4 weeks and then gradual return to activity by 6 weeks.

If Capela decides to have surgery, then this would involve fixation of the ligament with suture embedded into the bone to re-attach the ligament. For NBA players, this is usually 8 weeks to return to full play.

Regardless, he is not expected to return until after the All- Star break. This is a major hit for the Rockets who have little depth at center. Nene is expected to start, and PJ Tucker will rotate into center for their small lineup.

Challenges face the Lakers without Rondo

Hale Thornhill-Wilson

Just after the Los Angeles Lakers’ nail-biting defeat against the Sacramento Kings last night, further negative, interim news was confirmed that Rajon Rondo will miss at least a month of action with a sprained finger. Rondo suffered the injury during the Warriors game just this past Tuesday. Unfortunately, his finger sprain comes at quite the inopportune time for the veteran, as he had already generated a double-double in the game, prior to the incident. On top of having a myriad of finger issues in the past, the previous, four- time All Star has seen a major decrease in minutes while he plays second fiddle to promising second year point guard, Lonzo Ball.

Ball’s youth, promise, and unique size for a point guard is what keeps Rondo on the bench as the back-up point guard.  However, statistically speaking, Rondo has a standout assist to turnover ratio at 3:1, while Ball’s is a respectable (2.3):1. The skew in ratios is due to Lonzo’s more frenetic, rapid pace which typically correlates to more turnovers, while Rondo is the more methodical, facilitating- first point guard. Though he averages just under 2.0 points a game than Lonzo, Rondo’s percentages from the field are predominately stronger than Ball’s. It’s a prime case of efficiency vs. flashiness here.

Looking forward, this is a great opportunity for Lonzo Ball to showcase his improvement with the extended minutes Rondo has granted him. Look for Lakers to take advantage of Ball’s length and defensive prowess to establish a fast tempo. Ball’s great ability to launch outlet passes ways away and push the ball in the open court will provide a nice pace for the offense. Especially with Lebron out for a bit of time, Laker’s fans will truly see what the second year point guard is able to carry on his shoulders. Ball must keep the turnovers down and wisely chose his attacks to the bucket, so he can create for himself or his teammates.
