Shoulder Innovations makes medical implants used in shoulder replacement surgery. Its main product is the InSet shoulder system, a type of implant that surgeons place inside the bone to replace a damaged or worn-out shoulder joint. The company sells its products to hospitals and orthopedic surgeons across the United States.

The company earns money by selling its implants and related surgical instruments to hospitals on a per-procedure basis. It operates primarily in the U.S. market and, with a market cap of around $300 million, is a small player in the broader orthopedic implant industry, competing against much larger companies like Zimmer Biomet and Stryker. The company is not yet profitable, with an operating margin of roughly negative 57%, so its key challenge is scaling its sales force and surgeon adoption fast enough to reach profitability before it needs to raise additional capital.

Revenue accelerating

Shoulder Innovations grew revenue 65% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
